it might have 1 week or 10 years life nobody can tell ,i have this PSU in a pc that is turned on 3-4 hours per day at most ,so i assume has more life than machines runing 24h,the reason i always buy corsair PSUs on all pcs i make its because live LONG...
anyway i measured the voltage on all pins to be sure ,did the mod,everything works fine .
now i can have 3x power pcie and 3x 4pin 12v motherboard pins.
