Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (Low Noise, Zero RPM Fan Mode, 105°C Capacitors, Fully Modular Cables, Compact Size) Black

Bought this POS because it was highly recommended and Corsair has a good reputation as a brand for a top of the line PC build (x570 mobo, ryzen 9, etc). The first one died the day after installing it, after my computer went into sleep mode and something must have tripped electronically because it went dead instead. Replaced it, second one seemed to be working fine for a week, then the lights flickered for a minute and the thing completely died again. Both times, it was on a name-brand surge protector and was the only device that had an issue. I had another of these PSUs on hand for a duplicate build, but Im returning it and this DOA one. The 8-year-old Rosewill PSU plugged into an almost decade-old build thats been running 24/7 next to this brand new build 4x the price had no problems through these little flickers, despite being on an off-brand surge protector. One could have been a fluke, but two in a row going completely dead over the tiniest fluctuation in power says its a build problem. Im not rolling the dice with another and letting it fry my motherboard this time.

If I could rate less than a single star, for this product I would. Please, I’m warning you right now, you will be disappointed ordering this as I am now. It’s frustrating to have put up a whole PC just to have your power supply be completely dead. After running tests, we’ve come to the definite conclusion that this product was garbage. The box had rips and was sticky and in very poor condition while receiving it. When we opened it, two screws came out from inside it and while installing it, it would not even run at all. Completely dead! So if you are thinking of buying this, DON’T! Waste of money, waste of time. Never been so disappointed. Built many PCs and never had this problem. Never trusting them again. As I said already, do not buy!

quiet until under HEAVY stress with rest of the system. can get loud then but its doing exactly what its designed to do so im very happy

Love the fact that it carries 3 PCie cables

Absurd value, amazing performance, ridiculous warranty. More in-depth reviews by johnnyguru and others go in to the details pretty well, but the conclusion is straightforward; this is the power supply you should buy, period.

One Of the Fans in the computer burned up and took my Corsair power supply with it. Were was The Protection.

A Friend ordered this product for me. After 30 days we discovered our issue was low voltage output from this unit. The warranty process has taken an additional 30 days to receive a replacement. Their shipping department is absolutely slow... like taking the slow boat to, and back from, China!

Christmas gift for my 17 year old grandson for rebuild of gaming computer. He was very happy

Pros:

The stupid thing did not work
