XPG Fusion 1600W Titanium Power Supply Review

How Much Does it Cost?

The XPG Fusion 1600W Titanium Power Supply is a monster, completely overbuilt and over-engineered for a very specific and small set of use cases that simply makes it pointless for virtually all PC gaming builds. Few things make that truer than the eye-watering price, which what little stock we can find has a price slightly above £550, making it £100 more than rival models from the likes of be quiet!, Seasonic, Corsair, and amusingly, it’s still £100 cheaper than the utterly overpriced ASUS ROG THOR 1600W.

Overview

Would it be worth buying one of these for a gaming PC? Well, yes and no, it has some advantages, such as the truly exceptional efficiency, the best power factor correction I’ve ever seen, as it was near perfect, and it runs remarkably cool as a result, so if efficiency and heat are important to you, it’s hard to argue with the results of our testing today.

The power delivery is just fantastic, with very low ripple, consistent voltages at all loads and crossload, with good transients, making this a PSU that would be very well suited to extreme overclocking, where voltage tolerances can make, or literally break your hardware.

With a pair of 12VHPWR connectors, it’s capable of running any of the latest Nvidia graphics cards, such as the RTX 4090. However, that also means you could run two of them, or have one spare for future-proofing should next-gen cards require more than one. Or if you’re running a rendering rig or workstation, you can very easily power four Nvidia RTX A6000 or AMD Radeon PRO W7900 cards and still have enough PSU juice left to run the new series of Threadripper CPUs.

I would have thought a PSU of this size would be scary to test, putting it on our load tester I half expected something to blow up, or for some coil whine, or a fan to be spinning like heck to maintain its performance. But no, it was one of the coolest, quietest and most stable PSUs I’ve ever tested, and certainly the first time I’ve ever pulled 2000W+ from one.

Should I Buy One?

The conclusion of this review could not be much easier for me, as the exceeded my expectations in every regard. It pulls more power than it’s rated for, consistently and easily, it’s cooler and quieter, more efficient and more stable than just about anything else I’ve ever tested too. Sure, it’s also the most expensive I’ve tested too, but if you need massive power with no compromise, then that’s exactly what you’re going to get.
