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.

    Gives me a lot of wiggle room to upgrade in future. Modularity of it is amazing and even comes with a little bag to put spare cords in.

    High stand desktop psu. The cable is quite steady but hard to twist. I think model cables or model extension cable will be much better.

    Using it with Asus Strix 3090 and custom water cooling. No issues at all. PSU is more than enough for a GTX 3090.

    It's a Corsair PSU - so you know it works, it has lots of aftermarket cables for graphics cards, and it's reliable. Buy it.

    Great power supply if you get it at the right price, came with all the cables I needed and I appreciated the extra zip ties, etc., that come in the box for cable management. Overbought on the power supply so I wouldn't have to replace it as I upgraded other components.
