So I'm going to be working on my first build in a few weeks, but I'm a little lost on the power supply.
Heres my part list: http://pcpartpicker.com/user/ItsSoWonderful/saved/PnY2FT
I have 1 970 in there now, but Im actually planning to add a second one for sli a couple of months down the road, and I plan on overclocking the system, so how many watts do I actually need? I tried researching but I keep on getting different answers. Some say that 650 watts is fine but others say that I need at least 750 and then the online wattage calculators say I need like 500. So what do I actually need? Suggestions would be really appreciated.
