Customers are saying

Customers are pleased with the RMx Series 850W power supply's ample power, modular design, and quiet operation. Many appreciate the high-quality components and easy installation. While some users reported an audible coil whine, the majority found the unit to run cool and efficiently. The positive feedback on quality and ease of use outweighs the relatively few negative comments.

    Functional so far. However, I wouldn't recommend buying this right now, since the price is too high.

    The first one I got only lasted 15 to 20 minutes then died. Not sure what happened. Took it back and replaced and it’s been working great ever since.

    Good enough. Great price without going overboard. Part time mining with this paired with a STRIX 3090. No issues at all

    No problem yet. Only purchased because my old psu didn't control the fan and it was the loudest component in my system.

    Very solid build. Fan curve is nice but fan is smaller than last gen. Less cables than last gen as well.

    This is a very stable power supply but I could have used a 1000w as my system could use more power for overclocking

    It is a very good power supply which came with all the connectors that I needed. I find it a bit too pricy.

    Nice price and Best Buy matched a well known online competitor. They seem to be upping their game by catering more to PC builders.
