So I have gone through 4 psu's in the last year 3 corsair 850m's and an evga 750 nova. My build Is an I7 920 (not overclocked) evga 970ftw 16gb corsair vengeance 1600mhz an crucial 256gb ssd and a Seagate 1tb hdd. Now I have had my outlets tested and they are fine my sister's computer has never had a problem even running off the same line any one have any ideas?
