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.

    I love Corsair peripherals, but I never considered their psu’s. Top tier quality in terms of capacitors and rails. Great for mid - high end gaming builds. I personally use an i7-8700k and a 2080 Super and I have plenty of room for overclocking. This isn’t for you if you’re going for a budget build, there are much cheaper options with nearly similar performance.
