3ghz Power Consumption?

I figure this is a good place to get some input, so throw me your thoughts/knowledge, if you can.

I work in a company that is purchasing 3ghz Intel processors to upgrade our systems. I was putting in Antec TruePower 380's in there also, but we ran out. Our new shipment included cases with PowerMax 400w PSU's and we also got some of those by themselves (the PSU's).

Well, after deploying my first 3 systems, one of them started rebooting spontaneously, and so I disbled XP's reboot feature to try and get a better idea of the situation. It faithfully bluescreened an hour later and before I could get down there, it cut off. When I went to restart it, it wouldn't do anything at all. Upon testing it, the PSU was bad.

I was wondering right about then if we were going to have a problem with these PSU's, and so I decided to run my own little test. I loaded 3dMark on my PC (the new cases were nifty so I had to get one, and therefore had one such PSU), and ran it. It passed the video fine, and was on the second part of the CPU test when **POOF** it cut out. Once again, the PSU was dead.

My question is, do 3ghz processors have a special need above of the rest? Or is it strictly the cheap power supplies doing this?

I looked for info on this all day the other day and couldn't come up with any solid info.

Thanks for anything you guys can give me...

It's a problem of cheap power supplies. They are rated at peak instantenous load and probably have no overload protection.

If you need to keep the budget in check get the $36 Fortron 350W power supplies from <A HREF="http://www.newegg.com" target="_new">http://www.newegg.com</A>. They are the OEM supplier for Sparkle Power and Acer Power (under the Aopen brand), and have the best quality of any PC power supply manufacturer.

Congradulations!

You have just discovered like so many others that 400W doesnt equal 400W.

If you look at the current ratings on the sticker on the side of the PSU you will probably see that the 400W 'cheapass' PSU can do alot less than the 380 antec!

Once i saw that a 300W quality PSU put out more juice than a 350W generic. Its that bad.
Plus low quality PSU's also have a habit of dying quicker and easier.

Go get yourself some quality power supplies.
