New 1200W power supply PSU Corsair RM1200x Introduction
Corsair 1200w power supply.
Pretty much brand new, I thought I would need the wattage but I'm doing fine with a 1000w psu.
I've barely touched the cables since the 1000w one has the same connectors. Everything is still in the box which is a little bit beat up.
Price is firm, I can test it for you if you want.
Thanks!
