After building my own rigs for nearly 2 decades it is no great secret that I am a HUGE fan of EVGA! Not only because of their Step up program but because of the way they stand up for their Warranties!
I purchased a PSU for my back up PC and it came with a 3 year Warranty. When I registered it with EVGA they gave me 2 extra years on the Warranty just for registering!
That's five friggen years!
I don't think I ever got more than 3 out of a PSU but then again my PCs NEVER shut down, only restart
