HP EX475 Power supply connector

I have an HP EX475 mediasmart server which has just blown its second power supply. The PSUs always fail when MY UPS kicks in (I know this now!!) Whilst I look around for a replacement from another manufacturer I thought I'd use another PSU to get the server running again. I found a redundant PC PSU with an 20 pin ATX connector (it even had P1 stamped on it the same) I was just about to plug this in when something made me check the wiring. The old PSU and this PC one seem to be wired differently. I have buzzed things through and they do indeed seem to be different. The PC PSU complies with the ATX standard that I can find all over the net. The blown HP supply is different. How can this be? Surely a standard is a standard - it makes me concerned about getting a replacement that is wired correctly.

Any body else got any experience or advice?

I am really quite annoyed at HP over this.

It is a SERVER and needs to be available so it's stupid that it won't run on an ordinary UPS.

OK, so you build a server than won't run on a UPS and you don't tell anybody. We all have to find out by blowing up power supplies.

Then when the inevitable happens you can't even do a stop gap by using another power supply because for some crazy reason you have non standard wiring for the power supply connector.

Talk about making things easy - it's a catalogue of disasters.
