Corsair RMx Series RM1000X Power Supply Review

A Closer Look

The initial impressions of the Corsair RM1000x are certainly good with its solid weighty feel and sleek black aesthetics. It should be noted that when compared to other power supplies, this design does look slightly longer than usual, but even so, this shouldn’t prove any issue with case compatibility.

The fan section of the exterior presents itself well with a nice central location. In addition, the pattern of the vents are, while a little unusual, certainly eye-catching (in a pleasant way) which definitely adds to the overall look of this power supply.

The Corsair logo can be found to the center and with it’s lightly embossed effect, adds rather than detracts to the overall ethos of the design.

There is, of course, branding to other areas of the power supply. Again though, this is well done with it being clear, concise, well-sized, and overall in keeping with the visuals.

The base of the PSU has a label containing all of the detailed specifications regarding how the power is distributed across the various voltage rails. In something I definitely approve of, unlike a lot of alternative products, Corsair has kept this rather small with it being just less than half the width of the exterior case.

In a continuation of the triangle vent pattern seen to the fan section, the exhaust area again presents itself well with a decent amount of the area left open for good air flow. Admittedly, it’s a little disappointing that these vents did not extend to a larger area, but overall, it certainly looks good.

As a fully-modular power supply, the input bank is well organized which each section labelled to denote its usage. Yes, certain cables can only go in certain ports anyway, but with this design, even the novice should find this easy enough to figure out!

Cabling

The cabling comes within a black woven protective sheaving which makes it both strong and surprisingly flexible. Although the cable length isn’t overly generous, unless you have a particularly complex chassis, you shouldn’t have any problems getting all your components hooked up in a neat and tidy manner.

In addition, similar to the power input bank, all of the cables are labelled to denote their specific usage.

Internals – A Look Inside!

Starting with the fan, a closer look reveals this to be a Corsair own NR140ML design. As a 140mm fan, this is certainly a little larger than what we usually encounter within a PSU, but this is generally a good thing. Larger fans can, after all, move more air with less rotational speed (generally) required.

It’s always difficulty to ascertain whether the utilization of anti-vibration paste is a good thing or bad thing in a fan design. Given that one of the key features of this power supplies design is a low-operational noise output, however, we presume that this has been added specifically to help aid that function.

There’s certainly a lot going on inside the Corsair RM1000x’s PCB, but that’s not unusual given that this is a relatively high-wattage output design. On the plus side, all of the components looks well spaced and in particular the heat sinks which are well situated directly below the cooling fan.

A closer look at the capacitors confirm that these are indeed Japanese with them coming from the highly-reputable manufacturer ‘Nippon Chemi-con’. Rated to 105C, this is exactly what you want to see in any good power supply design!

Overall Thoughts!

Overall, the Corsair RM1000x looks fantastic both inside and out. Looks, however, are only one aspect of consideration in this review. It is, of course, also exceptionally important to know that this power supply can meet the pretty lofty targets set out within its specifications and features. Let us, therefore, get this fitted to our test bench and see what happens!
