Hi so i chose to buy a r9 390 for my computer but im not sure if my PSU will handle it, currently my system is:
Graphics: AMD Radeon HD 6800
CPU: AMD FX 8320 eight core 3.50GHz
RAM: 8GB
but i bought the r9 390 and im not sure if my 650W will do it

OCZ stuff is usually decent, but still we need to know the model.
