I have no idea what I'm talking about? Please go do some research you ignorant ass. A 970 pulls about 145w while the 4790s pulls about 120w, now you have 265w not including everything else, so lets round that up to 350w not only is it already at 80% load but with a z97 mobo I assume he wants to overclock and you always want to keep a psu at 50%-80% load. Pull your head out of your ass.
