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 power supply to replace an old aging OCZ 550w PSU that was starting to die and give system instability. The product is very well packaged and the pouch to store the wire is neat. Quality is also very good. It is good to know that this PSU is based on a CWT design. It is also rated as Tier A+ by Linus Tech Tips PSU Tier list.

very nice

Worth the money. Used one on a high speed PC. Plenty of juice for all the equipment I used.

Power supply shuts off. Worked perfected for a few months then my pc just shuts down randomly. Power cord is connected directly into wall outlet, all my cables are connected, and everyone else works fine. Just the power supply is broken. I can restart the pc again (by pulling out the power cord and replugging it) and it works fine for a while, then its shuts downs randomly. Ongoing cycle of annoyance.

I used this product to replace the PSU in my Dell Studio pc. It fit, but not perfect. Also, the fan is very noisy but it works.

I purchased the RM750 after I got a more powerful GPU for my first build. Up until then, I had been using a 600-Watt EVGA non-modular PSU (which was great and had enough power output, but didnt have two PCIe 6+2 connections). Going to a fully modular PSU was quite convenient since I didnt have a load of unused cables hardwired into the old PSU just gunking up the space under the case. The installation was easy enough, and this PSU has more than enough connections for most applications. The thing has been working flawlessly since, and is ridiculously quiet.

Had to RMA the first psu as it was DOA, but Corsairs customer service was great and they sent me a working replacement within a week. Thankyou Corsair.

This isnt Corsairs fault and I love the RM850x psu. I ordered one from this seller and received a Thermal Take 700w 80 plus inside of the RM850x box.

I heard this series of power supply is just great quality unlike the non-x series. So I bought this power supply to power my I9-10850K and 3060ti build. Its overkill for the build but I didnt want to skimp on a power supply. So far 7 months in, the computer is still holding up and the power supply is very quiet. Its worth the price. The only downside I will give the power supply is the cables it comes with. Theyll do for a build but theyre pretty stiff and can make installing and routing cables difficult.

May be inexpensive to purchase but will cost more in the long run when it fails. It failed in my sons pc and took out his graphics card. Amazon refunded for supply but did nothing for the 800 dollar graphics card it ruined. DO NOT BUY!!
