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.
