Review: Great PSU - Bought this after I had a PSU fail on me because I heard from friends and other reviews that Corsair PSUs were super reliable. They were right. I've had 0 problems. The cables are great, never had a power issue. Would recommend to anyone looking for a PSU.
Review: I got the (2024) model, not the (2018) model, but it's ok. - You’ll most likely be getting the newer 2024 model, not the older 2018 version, so it’s worth checking other RM850x listings, you’ll find it priced more competitively there. This particular listing should be updated to avoid confusion, since the older model is no longer being produced or sold. That said, the RM850x is an excellent PSU: reliable, efficient, & quiet. It’s just not worth paying an inflated price here when you can purchase the same unit for less elsewhere.

### ⭐⭐⭐⭐⭐ Great PSU
*by D***D on June 29, 2026*

Bought this after I had a PSU fail on me because I heard from friends and other reviews that Corsair PSUs were super reliable. They were right. I've had 0 problems. The cables are great, never had a power issue. Would recommend to anyone looking for a PSU.

### ⭐⭐⭐⭐⭐ I got the (2024) model, not the (2018) model, but it's ok.
*by Z***H on November 30, 2025*

You’ll most likely be getting the newer 2024 model, not the older 2018 version, so it’s worth checking other RM850x listings, you’ll find it priced more competitively there. This particular listing should be updated to avoid confusion, since the older model is no longer being produced or sold. That said, the RM850x is an excellent PSU: reliable, efficient, & quiet. It’s just not worth paying an inflated price here when you can purchase the same unit for less elsewhere.

### ⭐⭐⭐⭐⭐ Corsair quality per usual
*by B***P on March 8, 2021*

Bought this to replace an old 650x corsair PS I had in my last build for the current rig. That power supply lasted nearly 11 years people! Sure it was older and not modular as that wasn't a thing - but 11 years? My system is centered around corsair from the cpu cooler, ram, fans, pc case, mouse pad and psu. Everything runs flawlessly, simple to install with a focus on aesthetics and the cable management is insane - especially with that 5000d case. 850x is more than I require, but this is also future proofing as I intend to be using this psu for a decade or so. Its fully modular, meaning you can only attach the wires you need, which eases the strain of the cable management chaos. I have 4 cables attached to power the cpu, gpu, sata sdd backups and of course all the rgb modules on the back panel). Great, quiet and modular psu backed by Corsairs legendary quality.
