Strange Situation

[Fed]

I hate to say this but usually no post screen points to a faulty PSU.
Do you have any friends who will let you raid their computer for a PSU trial?

I don't know if you read the entire thread or not but I already concluded it was a Power Supply problem and bought a new unit.  The computer worked for less than 2 days and went dead again.

Does not neccessarily mean it is still not a PSU problem...

Yes I did read it.
The other alternative is to strip it down to the minimum and run it on the bench.
You may have got a dud PSU.

Been done.

You may have got a dud PSU.

It's inconceivable that both PSU's have the same problem.  Is it possible 300W isn't enough to run my PC?

Edit: By inconceivable I mean I hope that's not true, lol.

It's not inconcievable... i went thru a run of 4 bad PSU's lasting from a day to 3 weeks...all high end all from the same vendor. It does happen...

Thanks for that URL.

It says my minimum is 270, so that rules out a shortage problem.  Now, I guess all I can do is try for a third PSU?  Any suggestions if that fails aswell?

[patio]

You need to keep in mind how they rate PSU's...a 300W PSU is rated at max output under a sustained load...not an accurate way to do things but it is what it is.

I normally calculate a PSU for a third less than it's rating..IE a 300W unit to me is worth about 220W at best.

If your system tested out at 270W i would suggest a 400W.

Just my 2 cents.

Finally, something I didn't know.  Thank you very much.
