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.

    After upgrading from CM series to RM series, I will not go back. RM is more pricey but the noise and energy conversion is worth it in the long run. I highly recommend.

    For anyone building a PC with a gaming video card and CPU I'd recommend this PSU. I had an EVGA 750w psu but it couldn't handle the loads which were under 450watts.

    PSUs have been hard to come by lately -- so finding my favorite PSU brand's 850w RMx was a rare find. Best Buy pulling through!

    People thought I was crazy to buy a power supply of this magnitude last year. Fast forward a year, those same peeps are crying as their puny power sources can't handle the force of the the new RTX 3000 series graphics cards. Don't ever question me again internet noobs.

    This thing comes with a ton of cabling if you need it, or you can pick and choose what you need to hook up. Will be buying another one soon for a new build
