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.
Review: Corsair quality per usual - 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.

### ⭐⭐⭐⭐⭐ Great budget power supply
*by P***Z on May 19, 2022*

GENERAL INFORMATION As with all Corsair products, this power supply turned out to be a wonderful buy from a name brand - especially if you can snag it when it's on sale for just $90. PROS - Very limited noise level - almost completely silent - Doesn't crash/fail like cheap alternatives - Looks great in all-black PC builds, if visible - Built in cables are well designed - the SATA cables, for example, have multiple connectors on one cable to allow for insanely easy chaining. - Labeled cables. Sometimes, non-labeled cables can be hard to find where to place in your PC. These ones are clearly labeled: PCIE, CPU, SATA, etc. CONS - The price. It's a really nice price when on sale, but when not on sale, you can find some cheaper alternatives from non name brand companies. However, as this is a power supply, you should NOT cheap out on it. CONCLUSION I think this power supply nailed the job. It's a great supply for my computer with a 3070ti and 5800x. Really proud of this one.
