Your PSU should have atleast 2 of those 6 pin PCI-E connectors available. You don't need to cut off the extra 2 pin connector to use it. That is strictly for the bigger cards that require the 8Pin PCI-E connector. Just plug in the 2x6 pin connectors and leave the 2 pin hanging.
I understood I'm not using the attached 2 pin connectors, just the 6 pin connectors. What concerns me was the harnesses from my Coolermaster PSU has all 6 pins in each of the two 6 pin connectors vs the short stubby 6 pin connector harness that came with the EVGA card has only 5 pins on each of the two 6 pin connectors as noted in the EVGA manual. I hope this makes sense to those reading it.
So do I use the PSU 6 pin harness as is? Having all 6 pins connected won't hurt anything?
The connectors from EVGA are short and terminate into 4 pin molex connectots so I would need to use 4 additional cables to hook these up. Take a look at the pic and you'll see what I mean. I would prefer not connecting this way due to the additional harness clutter.
