HP Vectra VL 6 Power Supply Wiring

Hello all,

I have an old HP Vectra VL 6 computer whose Power supply failed.
The power supply connector is very similar to HP vectra VL5 (http://pinouts.ru/Power/hp_vectravl5_power_pinout.shtml) but has a 14th wire (colored grey), placed before pin 1 (as also mentionned by other users in reports section).
Also there is another 4 pin molex connector for 3.3V.

Does anyone knows what is the function of this pin ?
I tried to map a standard ATX power supply instead of the original PSU (based on 12/13 pin version found here) but it does not work.  :-\

Any help would be appreciated !
