I purchased the above mobo with an Athlon II x2 250 3GhZ processor (don't laugh) to upgrade my old system. Unfortunately I can't get it to work, it does not POST, no power to USB or PS2 and no display (have tried on board ATI Readon 3000 and a PCI card. The power light does come on and the CPU fan turns.
Have tried all the usual troubleshooting techniques. Just power + panel, no ram outside case etc.
I've read that power may be an issue, and my PSU (400W) does seem underpowered, producing only 12A at +12V. The spec required are 15A at +12V.
i just wanted to check whether it's worth upgrading the PSU before I send the mobo back, or whether the symptoms described wouldn't be caused by an underpowered PSU?
Also, I was wondering if it's possible to supply too much power? I'm looking at a 500W PSU replacement, that claims to produce 30A at +12V. Would this be an issue if the 12V rail only required 15A?
