Re: Tyan 2460/Dual Athlon MP hangs

[Philip Wyett]

Hi,

This issue has all the hallmarks of PSU problems. I had the same issue running 
dual Athlon MP's with a GeForce 4 Ti4600 until I switched the 400W PSU that 
came with the case too an Enermax 550W beast. The basic Tyan approved PSU for 
the 2460 is a M2463 (460W) unit when talking to my main vendor specifically 
because of all the problems with lockups and failures to even POST (Power On 
Self Test) etc.

Regards

Philip Wyett
