Choosing the right PSU

by davy08 / October 7, 2009 9:08 PM PDT

I have two computers that are down for the exact same concern.
They are a eMachine & HP Desktops
They both will not boot to bio's & all the systems hardware is running fine.
This is a straight question so I figured I wouldn't need to give the full specs of my systems.
My question is:
Can I use just about any PSU to see if the problem might be with the PSU for first testing them?
I thought of going ahead & purchasing the PSU's that go in the computers but if I don't need the same PSU's that go in them I could use some of the PSU's I have in my collections.
I have numourous ones but are differant wattage & differant sizes.
If they don't fit I could put the mobo's on the table out of the cases's & just use them that way to bench test.
That way I wouldn't have to spend more money on a new PSU & have more lying around collecting dust.
Both computers have come down to having a bad mobo but just want to make sure it's not a PSU issue on both.
I have used some of my PSU's to test both & the computers to power up the systems the same way.
Just don't post to bio's screen at boot.
No Video out put just go into safe mode on both computers.
Used differant moitors.
All fans are spinning.
The eMachine HDD lite stays lit all the time when booted up.
The power button on the eMachine glows green all the time.
The HP has no HDD lite that I can see but the PSU lite in the rear stays lit as normal & the front power button lite glows blue all the time as normal.
Tried numourous testing prodedures on both with no avail.
That quick answer for the right PSU's would be sufficient.

Forgot tho mention
Both the machines will not present any beep codes.
They do not have mobo lites on the boards.
They both have 4 cpu pins & 24 pin mobo power connectors.
I knew that would make a differance.

If the existing PSU is ATX....then any generic ATX PSU

should work and there are numerous sites that offer replacement PSUs for BIG BOX PCs by model number.

And if it is just a generic ATX PSU, your choices of good PSUs from all sources are endless.
