Im not that great at typing and dislextic like a drunk toad so bare with me and my bad grammar.
But i want to spit a few things about old psu's and psu's under strain. (psu = power supply unit)
That psu is past its Good date for a record time.
PSU's degrade over time, and requirements go up.. together they will make a psu fail at some point. the thing is how. if it fails badly it can take your whole system with it. (ive lost a 64 x2 6000+ this way)
realy depends what protections its packing. surge, thermal, short etc etc
i wouldnt cut costs on a PSU, Good psu is im
