Customer Ratings & Reviews

Very quiet, works well so far. Includes all your cables. Wish the cables were designed a little better to look cleaner but they work fine

No issues. You pretty much get what’s described when it comes to a PSU. Good bang for your buck, has more power than most PCs will ever need.

Works really well does what it says is good quality. Not much more to say about a osu but is fully modular and comes with bag for cables

this power supply will handle almost anything you throw at it, if you only want a performance computer then this power supply will suffice, it will not help when you want a top of the line computer and also want to water cool it since that requires at least 200 more watts. anything else if fine for it

Solid build quality, runs quiet at full load, comes with 2 x EPS & 6 x PCIe connectors ready for the next Gen Hardware.

Currently I just bought this power supply, it is great, its way of working in silence, it is very comfortable, I recommend it.

So far so good. Might need to update to a more powerful PSU as I keep adding more stuff but it's still holding up quite well.

Great PSU! Easy and simple to install, as well as very straightforward cables. Using this to power a 5900x and an EVGA XC3 Ultra RTX 3080.

Great PS, has way more than enough to fuel my mid-high end RPG gaming build. Corsair is reliable and the box is simplisticly stylized. Great choice.

I got this for my new computer build. I like how it's modular so that my rig looks clean inside. No problem powering a RTX 3080 with it!

Built my first PC with this and it is doing great. enough power for a Ryzen 9 a ton of rgb and RTX 3070 ti.

This is the power supply i use for every build and it has never failed me, it is simply to put together and gives you tons of cables to work with

Upgraded from a Corsair 650 watt 80 plus bronze which had a loud fan. The RM850x is very quiet. No problems running a core i7 8700k and a RTX 2080ti.

Perfect with my 3070ti and has plenty of headroom for upgrades in future. Corsair psu’s are a can’t miss especially this one.

Best PSU for Corsair. Returned my CX 750M and got this instead. Much more reliable for non overclockers and for the die hard overclockers.

I've had no issues with this power supply. It is working great. Seems well made. Supplied cables were excellent. I would definitely recommend.

Corsair makes some of the best power supply on the market and this 850 watt will handle all your needs and BestBuy has the best price.

Never had any issues, modular and enough headroom for a 3080 once I can upgrade. Could be smaller but that’s just the nature of an 850W.

Awesome power supply. Tons of power and runs real cool and quiet. Not the cheapest nor the most expensive power supply but was well worth the money.

Fully modular cables, so you only connect the cables your system needs. Fan size-5.3 inch. iCUE Compatibility-No. Modern Standby Compatible-No.
