Depends on the 650W. There are very good and very poor 650W units. You'll need to be a lot more specific.

What plug head?

 

[simonyeeklang]

Plug head = power supply 3 pin header from the wall plug.
BTW the power supply is 8 years old

And the power supply is?

Get a new psu 650-1000W that card will burn your old psu so fast as it is old under load. I burned mine with Sapphire Pulse RX Vega 56 and psu was 5 years old Corsair 750W not the highest end, but middle grade psu. Card should work fine with 650W, but old is old. At least try to get one ready for it.
