You could try it...

I think it may partially work, but the changed pins may not work.

I believe, starting in 1989 , dell made non standard power supplies that would toast a conventional board. or a std power supply would toast a dell mb.

some one commented that simply swapping wires was not enough.

there is supposed to be a $15.00 adapter/converter cable.

when a dell of that era is updated/repaired both have to be replaced with industry-standard parts.

some folks make dell ( warped style) compatible power supplies.

easy way: get an old atx mb and add a jumper/switch for connecting to the mb and starting it. what is a PII 233 atx mb worth?
also get a digital voltmeter.

search on google and you will find the complete info.

Thanks for the replies

Are H.P. Standard ATX power supplies ?

My uncle has an H.P.

he shut his computer off one day , and that was that it would not
Power up at all .

I'm guessing he had a virus: , wipe his bios ... Cmos .. softpowerswitch

But spending 10 bucks to see if it was the power supply would be
worth the effort .

A virus wouldn't likely cause it not to power up at all. You should see/hear some activity (LED's flashing, hard drive humming, something visual on the monitor). If there's no activity of any kind, more likely a fried P/S.

Information about CIH virus:

A more dangerous and deadly virus called "CIH" has spread rapidly and remains dormant in many computers. This virus will wake up or get activated on 26th of April and it will damage the motherboard and the hard disk. The damage caused could be extreme and expensive.

The computer motherboards manufactured in the last few years store their BIOS on a flash ROM chip which are rewritable. The CIH virus directly attacks the code stored in the flash ROM chip and makes the computer unbootable.

In certain motherboard the BIOS chip are replaceable and solution is possible by inserting a new chip. However in most of the cases the BIOS chip is soldered to the motherboard and there is no solution except to replace the motherboard which could be expensive. If the Flash BIOS is write-protected by jumper set then the CIH virus will delete all the data stored on hard disk, which puts every computer at risk irrespective of the BIOS layout.

At present there are 15 known versions of CIH virus which destroys the motherboard and hard disk. The first and second version will drop its payload on 26th April. The third version strikes on 26th June and the fourth version on the 26th of every month. These four variants are frequently reported in the wild.
