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

Very impressed with my PSU from Corsair. Its sleek, powerful and fully modular. Comes with everything I needed and more. 10/10.

Power supply worked for a short time but then started giving me issues. Needing to press the PC on switch many times to get it to turn on, then randomly turning off making click/relay sounds. I know it is the power supply because today I swapped it out for a new EVGA one. Works perfect with the new one.

Corsair RMX Series, RM850x,GOOD

I build alot of computers and Ive never has an issue with corsair psus. I prefer evga by a long shot. the cables are better and unit to me feels better. only reason I gave 4 stars instead of 5 is the cables. unit works great

Great power supply!

What you want in a power supply. Its quiet, fully modular, and so silly LEDs. It even comes with a little bag to store all the unused cables.

Works great however sometimes there are coil whine

Was good for a few days. Product installed fine and was performing quite well until last night. During routine use the computer did a hard boot and would fail to boot, almost as if the power supply was cycling. Disconnected all accessories and booted with just the CPU and Mobo. It would boot, but doing a voltage test would constantly drop below 12V to as low as 10 before Id shut it off....really disappointed. Waiting for an RMA and will install my old 750 to test, but based on reviews, there seem to be some bad PSUs out there.

Works Great

I just couldnt install it into my 4000d airflow
