Corsair RMX White Series (2018), RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply - White, 80 PLUS Gold (CP-9020188-NA)

Im only running about 380w on my home built computer so this PSU has plenty of room to add on. It was purchased as a replacement for an aged 1000w unit that finally failed. Ive benchmark stressed my system just see what the PSU fan sounds like when it kicks on; nothing. very quiet unit.

I have nothing outstanding to say since it’s a power supply, but I have no complaints either. It works perfectly, I’ve never heard the fan, and it powers my PC no problem

No issues with the unit until I attempted to hook up a brand new video card in my computer and fried it. Didnt understand why until I realized that the video card cables were not the originals that should have been supplied by Corsair in the box, but rather aftermarket cables that someone else had apparently returned inside the unit I was sent. Now too late for a return and Im stuck with a paper weight after buying a new power supply in store.

Great power supply. Very quiet w/ the zero rpm and love the fully modular design. No overheating or issues running 10900k w/ 3080. Good price too for the quality. Do wish they offered individually sleeved cables for a small additional charge instead of having to buy them separate for almost the price of the power supply. Would also like to see 1000w+ in white.

reliable power at a reasonable price

no fuss no muss, will buy brand again

Bought this Oct.24, 2020 and installed it as soon as it arrived a few days later. Today (May 24, 2021) it died on me. What a piece of junk! I will never buy a Corsair item ever again!

Used this in a recent build powering a i5-12400f and an RTX 3090. Handles both overclocking and undervolting remarkably well. Build quality is superb. PSU cables and clips are solid if a little stiff. Eco mode is terrific for when youre not straining your system and want a quiet experience. Perhaps best of all, this is known to be one of the best power supplies as ranked by independent power supply testers as a premium A-tier product. (Google: PSU Tier List)

Hoping item is still usable will update review if its still in working condition

Well built.
