xxkbxx Posted June 27, 2006 Report Share Posted June 27, 2006 Power supply overload? What is the brand/wattage? Quote Link to post Share on other sites
electrontau Posted June 28, 2006 Author Report Share Posted June 28, 2006 Power supply overload? What is the brand/wattage?As stated in my original thread, the power supply is Antec NeoHE 430W.With no drives (just CPU, mouse, keyboard, memory, and video card) it will not POST. I replaced the mobo and cpu with identical ones and still it won't POST. Quote Link to post Share on other sites
Sir_Siddy Posted June 28, 2006 Report Share Posted June 28, 2006 (edited) It could just be faultly. My old 500 watt PSU powerd powered parts of my system but couldnt do the entire thing but my new 500 Watt PSU does it just fine. A rail might be damaged or failing. PSU's are weird things sometimes...See if you can borrow sombody's or maybe buy one and then return it if you are still having problems.
