Replaced a bad power supply and now won't pass POST
I'm running this MB with an AMD Athlon 2400+. No big sound card or video load. It ran for a long time. It was probably on more than it should be. My daughter told me it just turned off while she was using it and it wouldn't turn on. I checked power connections and cycled the power and powered the unit up. It wasn't long before the room was filled with an acrid odor, so I powered it down and removed the power supply.
The unit I removed was a 450W. The new one is a 520W ARK technology P4-520W that should be compatible with my processor. It has a 20-4+ plug that I separated for my simple ATX board.
Is it common for a MoBo to fail WITH the PS? I didn't think so.
Any other Ideas?
Thanks... Curt

Power supplies are one of the most common failures for computers but as you have found they are also very easy to replace and a nominal cost.
I probably average 4 power supplies a week on my bench and always do as you did and suggest to clients to get a higher rated supply.

It is pretty rare for the PSU to take anything else out except in the case of a massive voltage overload on the input side as they copntain quite a lot of protection circiutry.
Glad to hear you got it sorted though.
Whenever I get a machine I am unsure about I do try components in a known machine one at a time.
This lets me know which (if any components may have suffered)
Quite often I still end up with just the PSU and even on occasion a fully working machine.
That last one always pleases my clients.
Youy may want to work your way through and may find you end up with a spare computer to play with or maybe sell to recover your costs for the replacement.

Reason. account termination.
A 520W will not hurt that board, now if after putting the 520W into the case and plugged in and you got no boot then you probably did kill the board.
The higher rated power supply these days is betteer for you in the long term as things to get upgraed your going to need more power to run.
So what you did was fine but if its not booting you might have a bad board as well. Power supply failures do happen but I have seen motherboard go before the power supply did due to overheats, ext ext.
I hope this was helpful to you.
