I have just inherited a dual xeon system that is a few years old. I have purchased a new case, power supply and other items for it, but have run into a problem.
On the old power supply (Delta Electronics DPS-600MB A) and mother board (Intel SE7525GP2) there is a connection that I can't find any info on.
It is listed in my mother board user guide as an "Auxilliary Power Connector", and it has 5 pins. The connector from the old PSU is labeled P14 and has 4 wires going into it (white, yellow, empty, black, orange).
My new power supply (corsair tx650) does not have this connection, so my question is: do I need this? If I power up the system without it will it do any harm? What is it and what does it do?
If it is necessary, is there some sort of adapter available?
