i am wondering if i should upgrade my psu its been powering my system build witch consists of an i5 3570k @4.1ghz,16gb corsair ddr3 memory.z77 sabertooth motherbord, 3 harddrives and cooler master HAF-X..i cant exactly remeber when i got it.lol but i think it was just about 5 years ago. its a corsair hx1000. and last year i upgraded a bit in the gpu and display department from going from a single 7970 and a bog standerd 1080p TV to sli 980tis and a samsung 48inch 4k tv. im not reaaly sure how to fully test if the psu is dieing. but since iv had it for so long..im wondering if it would be in my best interest to upgrade it and i was thininking to go with this
