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

After installing, wouldnt power on, dead on arrival. Amazon wouldnt replace it but gave me a refund, Im ordering another one but if its doa too ill try contacting corsair.

First and foremost, I just bought mine from Best Buy since they were in stock there and priced the same. Mine has been working amazingly. No issues, no problem. In fact, it was quite the upgrade from my Thermaltake 650w Smart Power (I bought that on Amazon). That PSU still works but it’s an eco PSU and terrible for gaming loads.

I know i am writing a late review. However, I couldn’t do so as i was busy with some work and then health issues so i couldn’t assemble my device. I bought the product assuming it to be a reliable product. However, it didn’t even start the first time. I thought I was doing something wrong. Then I took out my old cooler master smps to check and it worked just fine. It was then I realised that the new smps is not working.

For me this product pays for itself with the completely hassle free install. Yep!

Fully modular. Gold rating. It is a bit heavy, but overall quite pleased. It is powering up my Ryzen 3700 with RX 2070 super with no problems.

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.

Excellente alimentation. Seul bémol : une partie du câble 24 pin est tellement gros quil passe à peine au travers des passes-fils de mon boitier. Passez le fil de la carte mère vers lalimentation est pas linverse : ça aide.

I purchased this powersupply new from amazon warehouse.... it doesnt work, the PSU when plugged in doesnt even turn on...

I dont know if its the cables or the psu itself, but it never worked. I should have tested to see if it worked but instead I waited for the new graphics card. Now its past return and I am sad. Screw you corsair

DOA, quality control has gone.
