My PSU is a bfgr550wgxpsu(http://www.tigerdirect.com/applicati...942984&site=cp) and I've had it for about 5-6 years. I was wondering how much longer its going to hold out. Considering that BFG when under and the warranty is no long valid should I get a backup psu just in case? I know this may be a stupid question but I just had to ask. I do love this psu and I wish they still made them.
