Ben looking at the 20 pin connector when facing the latch side is face up
the third connection from the right is missing a wire just like the older
HP proprietary power supply connectors...

With that in mind I thought this was the older HP proprietary wiring
style, I will try a 300 watt Antec power supply replacement I have
tested...

This computer now basicly a re-housed HP 540n is going to a wheelchair
bound B+ Junior high student waiting for a replacement computer, her old
cobbled-together (pent11) finally died...

I had AntiX the small SimplyMepis Linux distro running well for her, and
she will get a newer system this afternoon with the same operating system
if all goes well...

Thanks for your well timed assistance again...
