Hello guys my built is intel core i7 4790k 4 ghz,Asus maximus vii hero,Asus gtx 970 strix,wd caviar black 1tb,samsung 256 gb ssd,corsair h100i liquid cooling,4 led fans corsair sp and af series,fan controller sentry 3, samsung cd reader.I might upgrade it with second gtx970 in 2-3 years and I want to buy a very good psu that will be sufficient for that built and never need to use more than 75-80% of the wattage it offers.I plan to overclock...im thinking of corsair ax760 w 80 plus platinum,I would like you to tell me if this is enough and suggest me any other psu that would provide quality and the needed wattage in my built.thanks alot
