Server power supply how to works on PC ?

hi@all

A few days ago was an old HP pro liant 740 server recycled and any parts i´ve rescued.
One power supply and one fan.
The power supply was a very strong version (1100W)
I do not point where and what must be connected with to can be pursued.
The connectors was an strip of pins (see pic)
Any ideas ?

Does your PC have a power supply and if so what do you expect to gain by putting in the 1100 watt one?

I still have old SCSI parts ,old SCSI controller and an old server Board with 4 processors on it.
10 hard disks on base SCSI, want to be also supplied with Power.
For test purposes I have 2 old AMD/ATI graphics cards (PCI-X) each about 300 watts of using
With 12 volts there are 600 watts already 50A only.
It would be a waste if I to me a new net part would have to shop, because I already one have with the achievement I need.

THe mating cable adapter would likely cost as much as a 450W brick. $50
If you are going to hardwire something, use a DMM to measure the outputs.

Some Cables for PC Adapters are exist. The problem was how connect ?
whitch pin use for what ?

This is something easily determined with a normal PC PSU and a DMM on server PSU for output voltages and 0V return
