Corsair Gaming PSU RM850x V2

Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. Built with all Japanese 105 capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. And, the fully modular DC cables make builds and upgrades easy, with clean, great-looking results. Gold certification ensures high efficiency operation for less excess heat and lower operating costs. Installation is faster, since you can mount the power supply in the case first, and then attach only the cables you need.
