CyberPowerPC Hyper Liquid Infinity PC Review

When thinking about buying a PC, you have two choices. The first is to build it yourself, and the second is to buy a pre-built from a system integrator like CyberPowerPC or similar outlets. Typically speaking, buying from a system integrator can give you huge benefits. You don’t have to deal with the manual work of building, you get a warranty, and often the value behind buying a pre-built offers significant upsides as system integrators generally have stronger buying power for components. This can result in savings being passed on to you, the consumer, or allow for a better-quality build than what you'd put together yourself with the same budget. Another major benefit is customisation. Using a configurator on the system integrator’s website, you can adjust the finer details like fans, lighting, and the all-important main specifications of your build. These are things you can do if you build yourself too, but the Hyper Liquid Infinity system we have today takes it a step further. With this system, you get a fully custom loop cooling solution. Not only does this give the PC a stunning visual appeal, but it also means your system runs cooler and quieter during those long gaming or work sessions. Before we dive into the review of the system we have in front of us, it's worth mentioning that CyberPower has revamped their configurator. Whether you're a die-hard Intel fan or a dedicated AMD enthusiast, there's something for everyone, from entry-level to high-end systems. The configurator allows full control over the base parts, cooling components, coolant colour, and even the level of overclocking, which ranges from no overclock to Pro OC (10%), Extreme OC (20%), and Ultimate OC (30%). Each of these options comes at an additional cost, so you can truly tailor the system to your specific needs and budget. Now let’s talk about the system we have here. Buckle up, because CyberPower has sent us one of the most extreme systems in their line-up. I’ll warn you upfront, this won’t be a budget-friendly option at £4999.20, but when you see what’s included and the overall quality of the build, you’ll understand why. The Hyper Liquid Infinity system is a powerhouse, designed to tear through AAA titles and handle 4K gaming with ease. This is a system built for enthusiasts who want nothing but the best. Specifications CPU - Intel Core i9 14900KS Motherboard - MSI MEG Z790 ACE Memory - Kingston FURY Renegade 32GB DDR5 6400MHz Storage - WD Black SN850X 2TB GPU - MSI GeForce RTX 4090 Suprim Case - Lian Li 011 Dynamic Evo XL Black PSU - Corsair RM1000e 1000W 80+ Gold ATX 3.0 Modular PSU OS - Windows 11 Home 64-bit CyberPowerPC Hyper Liquid Dual Loop - Black Thermal Grizzly Premium Thermal Paste EK CryoFuel Solid Azure Blue EK CryoFuel Solid Scarlet Red Corsair Premium Individually Sleeved PSU Cables Pro Kit Black With these specs, it’s clear this system is engineered to handle the most demanding tasks with ease. The combination of the Intel Core i9 14900KS and MSI GeForce RTX 4090 Suprim means that 4K gaming and high-intensity tasks like content creation or rendering will be no problem. The 32GB of DDR5 memory and 2TB of ultra-fast NVMe storage round out this powerhouse of a system, making it both a gaming beast and a productivity monster. Value So being honest, that’s a lot of system, but for the money, you’d expect nothing less. When CyberPower were looking to send this spec out for review, and the fact that we hadn’t worked with each other for a while, they wanted to make sure that it was something special, and the fact that it arrived on a pallet by a specialist courier company, things were already off to a good start, as this is the type of service you could expect as a customer who buys this type of heavy duty system, and I’m not joking when I say that, this thing is no light in the slightest. One of the major perks of buying from CyberPower is their Desktop Standard Warranty: 5 years' labour, 2 years' parts, and 12 months of collect and return, along with lifetime technical support. If you want more coverage, you can pay extra for a 2-year collect and return warranty, or even opt for a 3-year parts and collect and return warranty for added peace of mind. Now that you’ve got a good look at the specs and the service, in the next sections, we’ll break down each individual part of the build in detail, from the CPU and GPU to the cooling system, and how they performed during testing, including benchmarks, thermals, and more. Stay tuned for in-depth coverage of what the Hyper Liquid Infinity brings to the table in real-world scenarios, including gaming at 4K, intensive workloads, and the overall user experience. Packaging When buying a system, especially one as big and as heavy as this, you’d expect it to arrive protected and this is no exception with the main system arriving in the Lian Li 011 Dynamic Evo XL case box along with another smaller box too. Inside the system is packed within the foam that comes with the case. Normally I'd expect some form of expanding foam, but as the system came on a pallet and weighs a considerable amount, it wouldn't have benefited from any internal packaging anyway. Inside the smaller box, we found the MSI ACE motherboard box which is full of extras such as spare power supply cables, the WiFi antenna, kettle lead, CPU socket cover and other miscellaneous parts making it perfect if you ever want to upgrade or change your system components at a later date. Exterior In terms of first impressions, it’s a stunner with large glass panels on the front and the side and with fish-tank style cases becoming more popular than ever, it’s a great choice to show off a system of this nature. Speaking of the case, going for the Lian Li 011 Dynamic Evo XL is a true testament to showcasing the build in the best way possible. We all know that the 011 Dynamic series is one of the most popular ranges of cases on the market, and by using the Evo XL, we have more space for some of the largest components on the market that also generally run on the hotter end of the scale, like the 14900KS and RTX 4090. The case also allows for larger cooling capabilities because with hot hardware, you’re going to need more than ample thermal dissipation which is where a whole host of EK watercooling components come into place. The case included 4 USB Type-A ports as well as a single Type-C port, and 3.5mm audio jack at the bottom so plenty of connectivity options for peripherals, external storage and other USB based devices too. When configuring the build, you do have the option for laser engraving, of which there’s a select amount of logos and graphics to choose from, or you have the option for a custom message with a choice of three fonts, or you can send in your own image to have that put on instead. There’s also a CyberPower logo on the front of the case, next to the long vertical RGB strip that’s standard on the Lian Li 011 Dynamic Evo XL case and coupled with the build is a small remote for adjusting the RGB inside to your liking, which we’ll go through a little later on because it’s a real showstopper and is a way to further personalise the build to your needs and desires. Interior The inside really is what draws you in, because in terms of the styling, CyberPower have clearly thought out the design and location for the custom loop watercooling hardware and tried to utilise the space extremely well so that there’s mass amounts of airflow while also keeping a keen eye on the aesthetics. Nothing looks out of place and the components flow into each other well. Couple this in with 2 individual loops, one for the CPU and one for the GPU, they also sent us this build with 2 different colours, with blue for the CPU loop and red for the GPU, though if I was being picky, I would have gone with green to match in with the choice of NVIDIA graphics card, but again, this is something you could configure yourself on the CyberPower website. Not content on going lacklustre in terms of keeping temperatures down, they’ve utilised the watercooling in an extremely good way, plumping for a motherboard monoblock opposed to just a standard, and smaller CPU block. This should aid in not only keeping the 14900KS cool, but the surrounding VRMs too along with looking pretty spectacular at the same time. The motherboard in the system is the MSI Z790 ACE which is a premium, high-end board with a robust VRM solution that will provide more than enough power to our CPU while also giving us lightning fast features and connectivity and a unique colour scheme of black and gold with some added lighting on the dragon logo on the VRM heatsink that sits by the rear I/O and the ACE logo that covers the utmost M.2 heatsink and this pulses in and out with a yellow-gold effect that ties in really well. For the CPU, you have choices, but again, CyberPower wanted to show off the best of the best and for Z790, that means we have a 14900KS, of which we can’t show you as it’s covered by the monoblock, but with 24 cores, split between 8 performance cores (with hyperthreading) and 16 E-Cores giving us a total of 32 threads that can boost up to 6.2GHz, it’s no slouch, whether you’re gaming, streaming or even content creating. The only gripe with this CPU is that it does run hot thanks to its maximum turbo power of 253W but under a full custom loop, that’s going to fully negate that issue, leading to longer sustained levels of boost when you need it most. For the memory, there’s that extra added touch of RGB, which as we all believe, makes any system better and adds at least 10% more performance (I joke of course) but the Kingston FURY Renegade 32GB DDR5 6400MHz kit definitely ties in well and is fast enough to keep up with modern demands in terms of the system as a whole. I could argue that 6400MHz is quick but there’s faster memory out there, but CyberPower only give you the option for up to 6400MHz, though in their defence, unless you’re a hardcore overclocker, anything above 6400MHz enters the land of diminishing returns as you’ll be paying a lot more money, for not much extra performance so I do see it from multiple angles. For storage, which is found under that top M.2 heatsink, which of course, features a quick release connector, is a WD Black SN850X 2TB drive, so plenty of room for the latest games, especially as some games are now pushing over 150GB, though there’s plenty of room for more drives as the ACE board features a single Gen5 drive (of which it is populated by the WD Black SSD) as well as 4 further Gen4 slots, though if you’re rocking older hardware, there’s also 6 SATA ports, so no problem with storage options, and again, you can configure all of this when buying the system or add them in at a later date, though you will be restricted by the GPU and watercooling components in trying to get to the other M.2 slots. So the big one if you’re looking at buying a hardcore all-out gaming system, of course comes down to the graphics card, and for this, we have the MSI GeForce RTX 4090 Suprim with EK waterblock strapped to it. I’ve long been a fan of the Suprim version of cards, and while it’s a shame to have that shiny, bulky looking air cooler removed, because it’s typically regarded as one of the best looking cards on the planet, the hardware is still underneath the block, you just can’t see it, but again, much like the CPU, having a GPU waterblock mounted to it, means that we’re going to see sustained levels of boosting for a prolonged amount of time, especially as the Suprim range of cards come with a pretty healthy overclock as standard. So with big components comes big power requirements and the Corsair RM1000e 1000W 80+ Gold ATX 3.0 fully modular PSU comes into play. Being ATX 3.0 means that we have no issue with transient spikes and 1000W gives us more than enough power to cater for the components inside the system. CyberPower have also utilised Corsair’s premium individually sleeved pro cable kit in black to add another element of customisation to the build, and when configuring, you do get the choice of black, white or blue to make the whole build a little more unique. So how about the cooling? Well when it comes down to the watercooling and there’s a lot to go through, because CPU monoblock and GPU waterblock to one side, when building a custom loop build, you have a lot of choices in terms of radiators, reservoirs, pumps, combos, tubing and fittings. For the radiators, there’s two EK Quantum Surface P360M X-Flow’s, with one at the top and one at the bottom, so again, having a split loop design means that we have a dedicated 360mm for the top loop, for the CPU, and another at the bottom for the GPU. Reservoir wise, we have 2 FLT 120 pump/reservoir combos, one handling the flow of the coolant for the CPU loop, while the other caters for the GPU loop with again, different colours per run. CyberPower have also used EK Quantum Torque fittings in black, though I do feel they may have missed a trick as these fittings allow you to use coloured collars to add an extra level of customisation to the build, and from looking at the configurator, it doesn’t seem like this is an option, though it it were, of course, that would come at an extra cost anyway. In terms of the tubing, CyberPower have done a great job of bending the 16mm tubing accurately and by keeping the visuals on point with no unnecessary twists or turns and in terms of the angles, it’s pretty close to what I’d do myself. They’ve also included a flow meter on each of the loops so you can double check that your system is working correctly, because if you’re buying a system like this, it’s likely that you’re not in the know when it comes to watercooling, so having that visual aid most definitely helps, not to mention that flow meters do look pretty cool too, if you can excuse the pun. The last component to talk about comes down to the fans, and keeping the parts consistent, CyberPower have opted to use the EK 120 D-RGB black fans. These are 120mm fans and there’s a total of 10 fans pre-installed in glorious ARGB, though again, colours can be changed through the included remote. There’s 3 fans on each radiator, 2 in the rear, as the Evo XL supports it, and 2 on the side behind each FLT120 pump/reservoir. Due to the amount of fans, there should be no issue with keeping things running at a lower fan speed, while still keeping our components cool at the same time by striking that balance of noise and cooling capabilities. Lighting Now I mentioned that this system has a lot of RGB and has the ability to change things up with a press of a button, so without going through every colour of the rainbow in detail, instead, find our gallery of various colour themes that you could opt for, though remember that during the configuration process, you have full access over the colour of the coolant used in the custom loops, and while you can drain the coolant, flush it out and refill it with different colours, I’d typically say that if you know how to do that, you’d probably be building the system yourself anyway. What I’m trying to get at is that if you’re wanting a specific colour for your lights, just be sure that it matches with what you’re going for colour scheme wise with your coolant, though sometimes clear coolant or white are the easiest options because they go with everything, though of course, this is a personal choice specific to you as the user. Build Quality Now when buying a pre-built or custom build machine for a system integrator, you’d expect the build quality to be right up there, because otherwise, what are you paying for? For me, I’m not overly fussed, as long as the “business side” is looking good, and I think we’ve established that a lot of thought and care has gone into this system, so no complaints from me, other than the lack of coloured collars on the EK fittings, though interestingly, we did find a couple that had silver ones, so maybe a bit of an oversight, but it’s not exactly a deal breaker. It is worth looking at the cable side though, because while it’s not a huge deal to me personally, it can impede on airflow and having things clean and tidy can actually increase performance. Not by a huge amount of course, but every little helps, and when you’re spending thousands on a system, you want to make sure that love and care has gone into every element of it. It’s here where we found good use of zip ties and velcro cable ties to clamp the cables together, and considering how much RGB and how many fans are in this system, there’s a lot of cables, but this is partly helped by the huge amount of space that the case has allowing cable management to be quite simple. It’s also in the rear where we find a Gamemax ARGB controller, which ties in with the remote control. There are some cables, like the ones from the flow meters which maybe could have been tucked away better, but with small, thin cables like this, trying to manipulate them, without catching them on the fans can be quite difficult, especially with a system that is being transported from CyberPower to your home. Synthetic Performance So first things first. With any pre-built system, we want to make sure that everything is working as it should in terms of the clock speed, which as our screenshot confirms, it is boosting to 6.2GHz, along with the memory and making sure that it's running at its rated XMP speed of 6400MHz, and rated timings for that speed too. In terms of the memory, the best way to see the throughput is using AIDA64 which being an Intel based system, gives us oodles of speed across the read, write and copy tests, as well as low latency at 67.8ns. The Blender benchmark is a little on the low side, where we typically rely on the "classroom" result, but this could be for a variety of reasons including temperatures making the system thermal throttle but overall, it's within the range that we'd expect anyway. Cinebench gives us a single score that is right on the money at 136 points, while the multi-core score is slightly low at 2091 points. We'd typically expect to see a little over 2100 points, but this would be such a small percentage jump in terms of performance that it's still within margin of error. CrystalDiskMark is a good way to show performance of an NVME drive, like the WD Black SN850X that's installed in this system. Looking at the rated speeds of 7300MB/s read and 6600MB/s write, considering this drive is the boot drive, and is running Windows from it, I'm perfectly happy with the results that we obtained. The read speed is lower, but that's expected as the drive is in use for Windows, but the write speed is bang on the money. For 3DMark Time Spy, our scores align perfectly with what you'd expect and are consistent with what high-end systems featuring these components generally produce in this benchmark. To analyse a bit more into the Core i9 14900KS and its performance, we ran the 3DMark CPU Profile benchmark test, and this test confirms that our 14900KS is running as expected across various threaded workloads from single threaded, all the way up to max threads and demonstrate strong performance across the board. In the 3DMark RTX test, a system with an RTX 4090 would typically expect to see performance between 135 to 145 FPS so at 140.47 FPS, we're perfectly within that range, sitting somewhere in the middle. In PCMark 10, we had a score of 10183, which again sits perfectly within the range that's expected of a system with an i9 14900KS and RTX 4090 with scores typically being between 9,500 and 11,000. Gaming Performance When it comes to gaming, this system has a lot of power at its disposal and with games becoming more intensive than they've ever been, having the combination of a Core i9 14900KS and RTX 4090, puts it at the forefront of raw unadulterated performance. If that's not enough, especially with games being released with Ray Tracing baked into the engine or game itself, thanks to the Ada Lovelace architecture, you don't have technologies at your disposal, including DLSS and Frame Generation to increase the framerate in games without sacrificing too much in terms of visual fidelity and overall quality. The need for DLSS is quite clear when you look at the likes of Cyberpunk with Ray Tracing enabled at 41 FPS and Hogwarts Legacy, again with Ray Tracing enabled at 44 frames per second. Beyond that, every game that we tested managed to hit or surpass 60 FPS, and this is on max settings, leading to a smooth and overall pleasant gameplay experience. Some games went even further with Baldur's Gate 3, Dying Light 2, F1 23, Horizon Forbidden West, Spider-Man, with and without Ray Tracing, Ratchet & Clank, Shadow Of The Tomb Raider, and Starfield which all managed to hit at least 100 fames per second while maintaining the very best visual quality. Power & Temperatures Power & Temperatures are always going to be a stickler when you're using the most power hungry and quite literally, hottest products on the market. The Core i9 14900KS is a CPU that's notoriously been canned for its power usage and overall thermals, but with the assistance of the dual custom loop cooling solution, things were kept pretty under control. In terms of power consumption, we measured the CPU and GPU max power during each game run, and that's displayed in the following chart. Combined, you're looking at upwards of 600W of power being used concurrently between both the CPU and GPU, but going into this, we never expected power to be low, as we're utilising the very best components on the market right now and that comes at a cost of power consumption. Temperature wise, I was pleasantly surprised by what results we saw across both the CPU and GPU. In terms of the GPU, the highest temperature we saw was 52 degrees in Warhammer 40,000: Darktide with Ray Tracing enabled, but for the most part, games were hovering closer between 42 to 51 degrees. For the CPU, the lowest temperature we saw was 70 degrees in Dying Light 2, with the highest temperature being 86 degrees in Horizon Forbidden West, though most of our results were around the mid 70 degrees mark. Final Thoughts When looking at a system of this calibre, it's essential to appreciate not just the hardware itself, but also the attention to detail in every facet of the build. CyberPowerPC has truly gone above and beyond with the Hyper Liquid Infinity system, catering to enthusiasts who crave both raw power and stunning aesthetics. The blend of high-end components such as the Intel Core i9-14900KS and MSI GeForce RTX 4090 Suprim ensures that no matter what you're throwing at it—be it intense gaming sessions, content creation, or demanding workloads—this machine is ready to deliver top-tier performance. Where the Hyper Liquid Infinity really shines, though, is in its custom watercooling solution. This isn’t your run-of-the-mill liquid cooling setup; CyberPower has outfitted this system with two custom loops, separating the cooling for the CPU and GPU. The careful execution of the loop design, paired with high-quality EK watercooling components, ensures that this system doesn’t just perform well but does so quietly and efficiently. Whether you're cranking out a marathon gaming session or pushing your processor to the limit with rendering tasks, you can rest assured knowing that thermals are under control, allowing for sustained performance without the usual ramp-up in fan noise. The Lian Li 011 Dynamic Evo XL case is an excellent choice for housing such powerful components, not only for its expansive interior but for the way it showcases the build through its glass panels. Every aspect of the interior is designed to maximize airflow while making the most of the RGB lighting and custom tubing work. This isn't just a PC; it's a statement piece—one that you'll proudly display on your desk rather than tuck away out of sight. Then there's the meticulous care CyberPower puts into the overall presentation of the system. From the moment it arrives—delivered on a pallet by a specialist courier—there’s an unmistakable sense that this is a premium product. The packaging, including the additional box of spare parts and accessories, ensures that you have everything you need should you ever want to make upgrades or changes down the line. This attention to detail in customer experience is something that sets CyberPower apart from many other system integrators. From a configurability standpoint, the options are nearly limitless. You can adjust everything from the fans, lighting, and coolant colour, to even the level of overclocking—allowing for an incredible amount of personalization. CyberPower’s revamped configurator makes this process easy, giving you the tools to craft a machine that not only meets your performance needs but reflects your personal style. The ability to opt for laser engraving and even upload your own custom image adds another level of uniqueness, making the system feel truly yours. But, let’s not forget, this is no budget system. While we don’t have the exact price at hand just yet, it’s safe to say this kind of custom build won’t be for the faint-hearted when it comes to cost. The premium components, custom watercooling, and bespoke design features naturally come at a premium price point. However, for what you’re getting—a machine that’s built to handle anything you throw at it and look amazing while doing so—it’s an investment that may well justify itself if you’re looking for the ultimate in gaming and workstation performance. There’s also the peace of mind factor when you buy from a system integrator like CyberPower. The warranty, the pre-built assurance that everything is tested and works flawlessly out of the box, and the post-sale support all combine to provide a stress-free experience compared to the DIY route. Building a custom loop PC yourself isn’t for everyone; it’s time-consuming, can be costly if mistakes are made, and requires a certain level of expertise to execute well. With CyberPower, you’re not just paying for the hardware—you’re paying for peace of mind, and the craftsmanship that comes with a professionally built system. Speaking of peace of mind, the Hyper Liquid Infinity comes with a Desktop Standard Warranty: 5 Years' Labour, 2 Years' Parts, 12 Months' Collect and Return, plus Life-Time Technical Support. If you prefer even more coverage, there are options to upgrade: for an additional cost, you can opt for 2 years of Collect and Return, or even 3 years' parts and 3 years' Collect and Return, giving you greater flexibility based on your needs. If I had to nit-pick, there are a few minor areas where improvements could be made. The absence of coloured collars on the EK Quantum Torque fittings, for instance, feels like a small missed opportunity for extra customization. While the silver fittings still look fantastic, having an option to choose different colours would elevate the visual appeal even more, especially given the high level of customization that’s already available across the rest of the build. Additionally, while the system's sheer size and weight contribute to its robust nature, it's something to be aware of when considering where to place it and how often you’ll want to move it around. However, these are relatively small critiques in the grand scheme of things. The Hyper Liquid Infinity isn’t just a PC—it’s a masterpiece of modern computing. It’s clear that CyberPower has taken great care in designing and building a system that not only meets the needs of the most demanding users but does so with style and flair. If you're in the market for a high-end system, and you're willing to invest in the best components and watercooling solutions available, then this is a serious contender. When pricing comes into play, it will likely cement itself as a luxury item for those who want nothing but the best. But in return, you get a system that looks as incredible as it performs, with every detail carefully considered. It’s been a while since we worked with CyberPower, but I’m glad we’re working together again, and I’m glad that nothing has changed since our last foray, because they still build absolutely amazing machines that anyone would be proud to own and if is this is a sign of what’s to offer across the range, then I’m excited to look at more system in the near future. Should I Buy One? At £4999.20, the CyberPowerPC Hyper Liquid Infinity sits firmly in the realm of high-end luxury systems, and it’s not a decision to be made lightly. However, if you’re in the market for a powerhouse PC that excels in both performance and aesthetics, this system is hard to beat. With its Intel Core i9-14900KS, MSI GeForce RTX 4090 Suprim, and custom dual-loop watercooling, you're getting a machine that can handle the most demanding tasks with ease—whether it's for gaming, content creation, or high-performance workloads. The attention to detail in the build, from the immaculate tubing to the sleek Lian Li 011 Dynamic Evo XL case, makes this system as much a showpiece as it is a tool. While the price is steep, it reflects the premium components and expert craftsmanship that have gone into every facet of the build. For those who want the best of the best, without the hassle of building and maintaining a custom loop system themselves, the Hyper Liquid Infinity is a worthy investment. If your budget allows and you value both top-tier performance and standout aesthetics, then this system could be the ultimate addition to your setup.
