My current psu is a Corsair VS650, 650watts. Im planning to upgrade to a Powercolor PCS+ r9 390. It says on their website the minimum wattafe for this card is 750watts. Some websites like overclockers.net show that an OCed powercolor 390 at load took around 400 watts. Also on outervision.com psu wattage calculator, i did my full build, and the recommnded psu wattage was 580.
Im a little confused, any thoughts? Any response is greatly appreciated.
