I am putting together a system with
Z97 FTW
EVGA 02G-P4-2962-KR GTX 960 Superclocked
EVGA Supernova 220-GS-0850-V1 PSU
Antec P100 case
What is the supplemental PCI-E 6 pin connector used for and is it necessary because there is barely any space between that connector(it faces down and is at the bottom of the mobo, not out) and the PSU.
