I bought a powersupply from amazon warehouse since they were doing a 15% off sale and it was missing a few cords, so i returned it and up graded to a better 1200w platinum model because it was labeled as pristine-repackaged, however it was actually missing a second cpu cable! and now im trying to put together my Duel Xeon computer and im missing the second cpu cable. I was testing a few of the cables and the VGA labeled cable appears to fit the second cpu using the vga cord and the vga labeled slot (pcie) on the power supply, is it possible to use this cable as a temporary solution until i get the replacement order? 

I would NOT suggest using the PCIe VGA cable for your CPU. I would suggest to register the PSU here http://www.evga.com/support/register.asp then email EVGA at support@evga.com and request a replacement cable.

Aparently i cant post links to amazon. This was the product i bought
 
EVGA SuperNOVA 1200 P2, 80+ PLATINUM 1200W, Fully Modular, EVGA ECO Mode, 10 Year Warranty, Includes FREE Power On Self Tester, Power Supply 220-P2-1200-X1

Those cables 8 pin PCIe and 8 pin EPS (CPU) are NOT interchangeable. See pics below for differences. Although most power supply manufactures will recommend you buy it from them unless EVGA is doing something different (and I doubt it) the pin outs for 12v and ground are standard so as long as you bought another 8 Pin EPS for the CPU with the same gauge wire and rated at the same amps it should work. That said it's still recommended to use the cable that actually goes with the PSU to avoid instability in power as there are some cheap @ss cables out there that are low quality. 
 
The 8 pin PCIe has a different pin assignment so see below.
