I'm talking about removing my current graphics card and replacing it with the 770.Asus 770 needs 300 watts alone, you'd be smart to do the math with the free SPU calculator and then bump it up 15-20%. You may want to consider a new PSU in the 850 range?
Use this handy calculator and add everything thing up, add all the fan slots up even if not being used you may later for heat? Then take what it gives and add at least 15%-25% as a PSU will degrade about 1.5-2.5% a year. For me I want extra headroom on any power supply so I recommend 650-850w and if you want later to OC and add more GPU's then start at 850-1200.
