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.

    Great power supply that has been running without issue. The only reason I didn't give it five stars was because I felt that it was a tad to expensive.

    Very quite, beefy, high quality and high wattage for a pretty good price. Although the GF1 is cheaper which is why I'm rating this 4 stars.
