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.

    Purchased below price thanks to a price match and was very satisfied. The only downside is if you have a z390 board and want to connect the optional 4 pin cpu power it does not come with that but it does have two 8 pin cpu power cables for some reason. all around great psu from a great company.
