This is a used Corsair RM850 850 Watt Fully Modular power supply unit. It has 1 fan for cooling, a gold colour design, and comes from the brand Corsair. The unit is ATX form factor, with a maximum power output of 850W. It features modular connectors including 4+4 CPU, 24 Pin, and 6+2 Pin PCI Express. The unit measures 180mm in length, 85mm in height, and 150mm in width. I am not sure why this isn’t working but happy to try and answer any queries you might have about it. Thanks for looking
