I have a power supply that has worked perfect now for about 8 years it a Seasonic X series 750watt gold I have 2 other ones bought about same time in other systems also with no issues so I love them.. I'm going to build a new AMD system reusing memory and HSF but wonder about the powers supply. Should I or would you consider "NOT"reusing it or due to age and possibly not supporting some of the newer power schemes...if their are any. I have a Evga 650 G2 setting here new in box (bought last year price was too cheap to pass up) Thanks!
