Corsair RMx Shift RM850x 850W fully-modular ATX power supply (80+ gold)

I'm selling a brand new Corsair RMx Shift RM850x 850W fully-modular ATX power supply.

It's 80 Plus Gold certified, fully modular cables for cleaner builds, and designed for quiet operation with efficient power delivery. Comes in original box with all accessories and documentation.
