I wouldn't think twice about it if it was an A class PSU. EVGA has 10 year warranty on some of theirs. My guess is they would be fine for many more years. High grade units from Corsair, Super Flower, Seasonic and others would not bother me. Low end old units would not cut it for my builds. These are my opinions. I look to jonnyguru for anything I'm on the fence about.
