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: Fantastic PSU for any build! - Corsair isn't what I'd call an old school PSU vendor, but damn have they ever proven they're here to stay. My favourite PSUs back in the day were OCZ and PC Power & Cooling. They were my go-to vendors but sadly neither exists anymore the way they used to. Since then I've been using Corsair PSUs and I couldn't be happier with their performance. I have a Corsair HX850 as my original modular PSU, so when I went to build my new PC I picked up this RM850x model. It's fully modular, it's whisper quiet, it isn't too long, and it has all of the connections you could want. But what sets this unit apart is that it comes with TWO CPU connectors! So you can hook it up to a motherboard with an 8pin and 4pin connector for the CPU. If you're doing any serious overclocking with an i9 or Ryzen 3900+ this is absolutely the PSU for you. The only thing I don't like is how the connectors have this extremely stiff wrap near the actual plug ends. While you can still do a clean cable build in a case, these stupid stiff wraps will prevent you from being able to twist or curl the cables so that they aren't sticking straight to the side for a couple inches before going back to being a regular cable. Why they chose these stupid wraps I'll never be able to guess, but they unfortunately exist. If you're using the stock cables this unit is a 9/10, with the point loss for those ridiculous stiff wraps. But if you're going to use cable extensions or aftermarket cables then this unit is easily a full 10/10.

### ⭐ Avoid GREZ LLC.
*by C***S on 10 June 2022*

The product is fine, but do not purchase from this item from GREZ LLC, they will charge you more than double the average price and their returns service is the worst I've ever experienced.
