Im trying to find out what the pinout of this Power Connector is.
Its kind of ATX, it has the same length with a gap.
Anyone know more about this connector? What is the standard used for this?
I dont have any connector cables for it..

The server has also a Power board between the PSU and the Mainboard.

Best guess is that power board splits the PSU odd pinout to the boards odd pinout.

i ordered me 2 cables from other Proliant server models. 1 x 10pin and one 12pin.
When they are 1:1, fit in the plug and dont have a twist they should work.
Im still missing the cable from the PSU to the Powerboard. Pretty sure a ATX PSU can deliver the same volatages.
