i dont OC,
CPU type: Intel(R) Core(TM)2 Duo CPU E7400 @ 2.80GHz CPU Speed (GHz): 2.82 System memory (GB): 3.249 Graphics card model: NVIDIA GeForce GTX 260
Seems the power supply has died and need to replace
The one linked by hunter315 is, but it is spread out across four 12v rails at 20 amps each which will be plenty. Also Newegg just sent out a promo for this PSU to get it for $40 after Rebate with Promo Code EMCYTYV23.
This little beauty has 50amps on a single 12v line and was reviewed by hardware secrets which showed great results, 2year warranty free shipping. I have seen it as low as 49.00, also the 630watt is continuous rate with 730 peak.
It also holds up well against electrical cutoffs (lightning in florida) the holdup time is long enough not to kill system while my sons and my prior one always took a dive.
