Hi,
I have an HP Pavilion XE763 that a friend gave me that won't power on.
My first instinct is to check the PSU, but the ATX connector is weird.
One pin has no wire, another pin has two wires, and there is a three
wire connector marked as "FAN-C" that plugs in to what looks like a fan
header on the mobo.
Does anyone have the pinouts for this power supply, or know if a
standard ATX PSU can be made to work, if only for long enough to see if
the HP PSU is dead?
Thanks
Terry

standard ATX pinout.

Based on the pinout Pen provided, it is standard ATX.
It is not uncommon for an OEM PSU to simply omit a wire or
two for voltages a modern system does use anymore (like -5V
or -12V). Having two wires on one pin is typically done to
remote-sense the voltage and that is done on any good power
supply.
The 3 wire fan connector is optional, usually does not
"need" to be connected at all for proper operation of the
system.
Check it just as you would any other standard ATX PSU.
If it has the same external casing dimensions as ATX PSU,
yes you can use a (different) stadard ATX PSU. This is
going by the link Pen provided and considering the details
you supplied. If it is not using the standard ATX 20 pin
motherboard (plastic) connector then supply more details
about it.
Turning such a PSU on is done by shorting the PS-On, pin 14
(usually a green wire) to ground while a load (like an old
hard drive) is connected. At that point the fan should spin
and voltage readings can be taken with a multimeter.

It has a small casing, so a standard size PSU won't fit. The ATX MOBO
connector is a standard 20 pin tho. I've tried jumping the PS-On to
Ground, but nothing happened.
I'll be digging out a working PSU to test the system this weekend.
Thanks for the reply
