s5520sc 5 pin auxiliary power signal connector

I have an Intel s5520sc dual xeon MB that has a 5 pin auxiliary power signal connector that is required to be hooked up for the board to boot. I have a Corsair AX750 that has all the required connectors execept that one. Any one else have this problem and possible solution? Apparently it monitors the power supply, and won't boot without it. Do any other power supply have the dual 8 pin cpu connectors and this auxiliary power signal connector?

 

Here is the pinout of the connector from intel (the power supply on their chassis)

 

Pin Signal Color

1 SMB_CLK_FP_PWR_R Orange

2 SMB_DAT_FP_PWR_R Black

3 SMB_ALRT_3_ESB_R Red

4 3.3 V SENSE- Yellow

5 3.3 V SENSE+ Green

the PSU(s) that goes with that board is proprietary to the chassis. you cannot use any Corsair PSUs with that. its the wrong spec. Corsair uses atx 2.x but that board requires a non atx spec PSU. Intel forces you to buy one from them unfortunatly.
