Awesome best pay I could’ve got for the price 6767

Runs my high end pc with no issues and its 50 series ready

I recommend this PSU to anyone that is looking for a nice budget build. For a good Quality power supply for this price it's nice definitely helped me out with my budget build im working on.

My last Corsair RM1200 lasted me from April 2015 until May 2025. So naturally I went with the same brand. Solid PSUs.

Good emergency replacement PSU. My Father in laws PSU messed up, hard to replace it fast. Couldn't beat the price and availability.

Good value for the money; it supports my 5080 just fine.

had to return because i got a defective one. I generally have good experience with corsair products outside of this instance.

Great quality psu for my pc. Can’t go wrong with 850w

Great Power supply. It runs my 9800x3d and 5070 ti with not issues.

Great PSU however I wish I had gone for the non -e variant this is still a fantastic psu but I know the X has better components and could help the unit last longer.

10/10, works as intended, My power supply shorted and this worked perfect as a replacement

These are straight up junk. I bought 1 and 7 days later it started crashing with a burning smell coming from it. I exchanged it and within 10 days the same thing happened to the new one. By then I'm past my 14 day warranty and out of a lot of money. I ended up getting an $80 psu on amazon and its holding up much better than these

The power supply itself is good, it's the thin cheap cables they come with now. Used to be, the cables were bundled together in a well wraped casing, now they are just a buch of thin wires capped at the ends and make cable management a pain.

Good PSU except you can not buy replacements for the all white cables that come with it from Corsair. They only offer them with black connectors/plugs.

Honestly I’m not happy with how Corsair has been building there products lately the unit right out of the box didn’t work not my first rodeo with this. troubleshooting the problem led me right back to this psu and honestly it could have been just the 1 and million but I can’t say I like this one now the 750 I’ve had no problems with and still use in another build but it is the older version of there rm line now I will say the cables from Corsair are amazing quality

The cabbles are nearly impossible to remove from mobo once they are installed. Atx3.0 connectors are not very friendly.

Warranty should of covered this why have warrantycrazy

the unit was not functioning. tested from different system dead.

Headed back to Best Buy to return my 2nd power supply this week. Corsair has no customer service or technical support. I would has been fine if they had someone to help troubleshoot the unit. My only option is to return it. Both power supplies would turn off 1 sec after connecting PS-ON and ground with nothing else connected.
