Turning on an old Psu Answered

Hey there,

I got this old PSU, a Delta DPS-350EB-3 from an HP NetServer. I'm trying to make a lab power supply out of it, i just can't get it to power on.

There's a blue wire bundled with a ground that when shorted will power the psu for a second then shut it back off. 

I tried to put a load on the 5v & 12v with no success.

Anyone got an idea?

Thanks

See if you can find the HP service manual for the server.
They are free. Just do a web search.
I just browsed a manual. Looks like some server models
have power control modules and power management boards.
Perhaps It will give you a clue as to what wires need to be jumpered,
or maybe something else from the server needs to be added to your setup.

Was the power supply good in the first place or was that why it was scuttled from the old computer?

There might be a problem with some of the PSU components.
I have seen bad capacitors inside of power supplies before.
Be careful if you open up a power supply . Unplug and discharge the capacitors.
