Adapting Corsair CX600M to dual EPS

I've recently been working on a home multi-purpose server and just picked up a great deal on ebay for the motheboard, cpu, and ram. However, now I have to figure out how to power it. The motherboard (Supermicro X7DWN+) requires a 4(2x2) pin connecter and an 8 (2x4)pin connector (EPS/12V, I think) in addition to the 24(2x12) pin atx connector. I have a Corsair CX600M, which I really hope to use for this, but it only has one 2x2+2 ESP connector (note, powering the 24pin isn't a problem).

I have read about a couple solutions to this problem online, but have no idea which one would work best. The cpu fans will not turn on if I only power the 4pin, only the 8pin, or the 4pin and half the 8pin (though I am not completely sure its not posting because I don't have a VGA cable on hand), so I assume I need to adapt another one of the power sources to fill the remaining pins. I have thought of adapting the 4pin molex accessory cable to 4pin esp/atx, or perhaps adapting one of the PCI-e 2x6+2 connectors.

Any suggestions or help would be greatly appreciated. Thanks in advance!

Thanks for the quick reply! I can actually get that supply for quite a bit cheaper (still from a very reliable source) so it seems rather perfect. Now a follow up question: for only $10 more, I could get the 750W version of the PSU. The CPU's are dual Xeon E5420's and I *might* add a midline graphics card sometime in the future (like GTX950ish max). Do you think the extra power is worth getting?
