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

Installed the PSU in a system that should draw 550~600 watts under load and noticed a few months later that some of the plastics in the unit had melted. Seemed to be something that a power coil was wrapped around. PSU is still functional but I certainly dont trust it enough to use it again. Recommend you go with EVGA instead.

item was dead on arrival, I figured it must have been my pin connections to the mother board. but when I swapped it out for my older Thermaltake PSU, my PC worked flawlessly. This PSU did not work in my older pc. Absolutely nothing, not boot up, no fan spin, no visible or audible signal from my PC nor the older PC. Buy if you want, but be informed that you may get a defective item.

I purchased this PSU as an upgrade from the factory unit in my Dell Optiplex 7010 MT. If you are looking to put one of these in this same type of PC, a word of warning: this PSU barely fits. I thought I would actually have to return it, but I was able to squeeze it in while sliding the side panel latch forward. Luckily, the latch still moves back enough to allow the side panel to stay closed, but the latch does rest against the PSU.

Solid power, good build quality (the cheap caps on my old Zalman are what took it out).

Very silent. Fan starts working under voltage load only.

Stronk power supply. Been running strong for 5 months now. Easy to install.

We used nothing but Corsair power supplies at my work. We never had any issues whatsoever. Its quiet and handles all my components with plenty power. I love that its small and just as powerful as an ATX power supply.

What I needed, perfect

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.

Little expensive but have had no problems would recommend
