Hello,
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?
Any info would be great, thanks!

i have just purchased the same motherboard and have the same question. i put in a new power supply and plug it in and nothing happens. do you have to have that auxiliary connector connected.
Hi all,
I am stuck up with the same issue, after buying a expensive powersupply from ebay i found that i does not contain 5 pin aux, There is a 4 pin power in the power supply.
I spoke to intel they said its a standby power connection for the PCI express card and they recommend me to get a full compatible chassis which has a power supply with 5 pin aux. That is $400 and the same price of my motherboard.
I have an vague idea that if i cut my 5 pin connector from my old power supply and connect it to the new one cutting the 4 pin connecter, the 5 pin connector has only 4 wires attached and middle one is empty.
I spoke to intel about this and he was like laughing and told me to do at my own risk, if anyone can pls figure out if this is possible.

It's an old power signal connection for Intel server motherboards.
Intel server motherboards used to require 3 power connections - a large main power connection, a smaller cpu power connection, and the P14 auxiliary power signal connection.
Power supplies with the P14 power signal connection are still available from online vendors.
lobstrosity - Here are links to your server power supply:
Jusmacn - An adapter cable is an excellent idea but the P14 connector is a 5 pin connector, not a 6 pin connector. Take a look at the photos the OP posted.
