My PSU in my main system died yesterday. I do have a Corsair AX1200 Sitting here. The old system is a Intel D875PBZ board. Its a ATX v1.3 PSU that died. 20 Pin connector with a 4 pin connector. I know on the corsair you can remove the extra 4 off the 20 pin to make it a 20 pin. My question is that 4 pin that detatches the connector i need? I know the 4/8 pin one for current boards isnt the right one.

Any help would be great.
 
the 24-pin connector is the same as the 20-pin connector just with 4 extra pins.

These 4 extra pins serve NO other purpose, and it is NOT the same thing as a 12v 4pin connector on 20/4 powersupplies.

The 8-pin 12v cord on a 24/8 powersupply is also the same as the old 4-pin connector, simply with 4 additional pins. That is what you need to use for the 4-pin socket on your old board, likely via an adapter if the cord itself doesn't break apart into two 4-pin blocks.

Back when I upgraded from my rig with dual Prestonia (northwood equivilent) Xeons to a Q6600, I was able to re-use the older server powersupply that I had because it was also 24/8 (the older EPS12v spec which, with minor changes, basically became the new power supply spec for desktops also). The motherboard had a 24-pin ATX connector but only a 4-pin 12v connector. I had to do a bit of ghetto modding but attached my own 4-pin connector to the existing wiring for the 8-pin 12v cable. Worked fine for quite some time.
 
ok instead of buying a adapter ill just pay 10 more for a power supply to tide me over till my build is done. Thanks
 
The 8-pin EPS12V connector is a 4-pin P4 connector with an extra four pins added on. Split EPS12V connectors exist specifically so that they can be used with motherboards that only have P4 connector sockets. That's what you use.
