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 bought this to replace an old Corsair PSU. It worked beautifully for three months. Today, at the 3 month mark, I turned on my computer, was able to use it for 20 minutes, then it shut off and wont turn back on. No power problems anywhere else in my house. Ive enjoyed Corsair products for about 8 years, but this is unacceptable. Go to a different brand for your PSU.

Great choice for my do it all AMD Ryzen 3600 x570 build. I run ZFS on Linux to all sizes of HD, SSD and now M2. Steam for games on an Nvidia 1660. Boot options for Win10, Fedora and Ubuntu, plus libvert and docker containers from Linux. This system is in my bedroom and far quieter than the older Dell it replaced. All fans hardly ever run, not sure if the power supply can has run more than the few seconds it does every reboot. The power supply can probably less than a minute runtime total after three months of powered on idle and active use.

I don’t like to wait for product come to me then is not working

Power supply works great when it turns on. If I shut down the pc wont turn back on until i jiggle power cord and unplug it a few times. Tried different power cords, different surge protectors and directly in the wall. Same results. Disappointed and now i have to find a new power supply.

It works great

I have a ton of fans so idk if it’s the PSU but overall it’s very good for my pc

Really quiet! I had picked up a seasonic focus gold previously and had some electrical whine that wasnt solved by a new unit. This corsair came on sale so I got this for the same price. Overall Im very happy.

Hace tiempo necesitaba una fuente para mi PC ya que estaba usando una fuente genérica y está nueva fuente va de maravilla

Overall a great PSU. I gave it 3 stars for Easy to Install and Ill explain. Full Modular PSUs should be able to just unplug one PSU, swap in a new PSU, and plug in. With out the need to swap out all the power cables. However this is not a truth. The headers will match, meaning they will plug into where they are supposed to plug into. But, the wiring will not always match. So lets say on your current PSU for cable A. The number 1 wire on your current power supply is negative. But on your new power supply the number 1 wire could be positive. This can cause your components to either not turn on at all or in worse case scenarios fry outright. If youre new to using or swapping out a fully modular PSU for a new fully modular PSU you will need to remove all the power cables and use the cables that come with the new unit.

Great for extra power as needed.
