Customer Ratings & Reviews

Corsair RM series one of the most reliable power supply out there. Was very supprised to find that best buy had it instock and at the same price as MC.

Needed a power supply upgrade for my 3080 TI and this is just what I needed. Easy installation, clean power. Couldn't be happier.

If you are a power builder such as myself this is the go to for clean power to your machine. The configuration makes it extremely easy to install or configure for your needs.

this is the heart of any pc build.. even the best processor is nothing without proper power. this psu stablized my oc. power isnt an issue with 3600x and rtx2070 super.

Replaced a 650W Corsair with this RM 850 to power a 3090 FE and GTX 770. No issues so far and exactly what I needed. Modular cables are a nice touch.

I purchased this to replace a 600 that had gone bad. It was reasonably priced and easy to install. Just plug in and go. No issue whatsoever.

Tried two other PSUs from major brands and it is the best PSU. Very very quiet and perform nicely for my new RTX 3080. All Corsair products are top notch.

With a big video card this 2080ti is the way to go. Powers multiple 4K monitors with ease. The 11gb of internal storage lets you render like a monster.

Amazing for the only one that Best Buy had. Fully modular power supply and it gives me more than enough needed with many connections to various connectors.

I bought this as an upgrade from my old power supply. I've had no issues with it and I love that it is modular. Definitely recommend for those who have a hefty gaming rig.

No one raves about their power supply. But this model is great for a demanding PC. High quality and modular connectors are very nice. It is a bit pricey.

Used this power supply in a recent build, worked perfectly. Modular design means I only used the cables I needed, and airflow is good inside the case.

The modular design is a must for custom PC builders with all the energy efficient PC stuff now a days this PC is pretty much all you need to run anything.

This is my 3rd Corsair PSU's. Three seperate builds and they are reliable and always work. Easy to find custom cables for too because they are a very popular brand.

This is a very good product I wouldn’t buy the 750 watt series from Corsair. This one worked the other one didnt Instructions could be a little more clearer

Nice modular unit, with plenty cables and length to connect everything. I haven't test the power output efficiency but have no problem running 3 gpus

Nice fan for the price. Works great in my pc. Drives my 2070 super with no problem. If your going to do dual graphics cards then I’d recommend a higher power supply.

Absolutely great. So far so good, no heating issues. Got it for my EVGA 3080 ftw3 as 3x8pin connectors are a must imo. I did not want to daisy chain even though the general consensus is that daisy chaining one connector is fine. My first 3080 came DOE and since it was EVGA I got an rma the next week. After waiting for months to get one, I did not want to take any chance despite having a 660w platinum plus psu as I only had 2 pcie connectors for it and I’d rather have extra headroom than try to undercut the 750w suggested minimum for a 3x8pin gpu.

Excellent quality and worth the extra money. Ran into no problems with setup and all work with Corsair PSU's has resulted in a successful first boot.

I saw another reviewer say this fixed coil whine coming from an EVGA G5 which I was also having a problem with. This fixed my problem thank goodness!
