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

I am using this power supply in a network storage unit where I house copies of data, pics, and security camera video. The power supply appears to be of good quality and works well. The fan is very quiet. The unit is modular and came with all the cables I needed for my installation. It seems to run cool and is not causing any heating issues in my PC case.

In the package the 4 screws that come with it to secure the PSU with the case are missing.

the modular cables are nice, i bought this on sale at the time for $70 i think and i am very impressed with the quality and over all silence of the PSU even compared to a CX corsair PSU that i replaced ( it was the second loudest thing in my system, aside from a hard drive ) how ever now i have this PSU and SSDs and a totally silent PC

I got this to replace a failed power supply, and am exceptionally pleased with it. While my old power supply had modular SATAPCI-E power supplement cords, the mainboard ATX connectors were hard-wired; This Corsair offering uses modular connectors for the mainboard as well, making routing, connecting, and keeping tidy the cables even better. Does what you expect of it (powers your rig), looks spiffy, modular design means less superfluous cables stuffed in odd nooks, and improved ease of installation in tight cases. Literally could not think of any design improvements, and while the last remaining concern is longevity, which takes time to assess, as this is a Corsair product I have a track record from which to draw expectations (which are that itll outlive the mainboard it serves).

good

Got it all set up and it worked well for the first 2 days and then died on me an hour and a half into turning on my pc. Tried multiple things to see what was wrong and fix it but would just click and even spark. I know my friend has the same exact psu and has never experienced this problem so this is quite upsetting recieving this faulty unit.

i7 CPU, 6800XT, et al, no problems

Whenever I wiggled the AC cord the power supply would shut down. Traced it down to a weak internal space connector. The AC movement was moving the back plate, which in turn was wiggling the internal connectors. Talk about poor quality.

Got this as part of a new build. Its the first power supply that has come with cables exactly as needed by the rest of the system. Its modular so initial unpacking was a surprise till I figured it out.

Was perfect for my pc
