Hello, sorry for making another thread on this, but I thought it would be a nice place to summarize the state of the 980 Ti for the Mac Pro.
I'm soon going to buy the 980 Ti for my Mac Pro 4,1 -> 5,1 hack. I would like to know which cards is recommended in different powering situations.
I'm mostly looking at eVGA's products as they are pretty competitively priced. (MVC's 980Ti is unfortunately out of question for me right now as those prices are ridiculously high in my country.)
1. If I power the card with the two mini 6-pin only, which version would work best? (if at all..)
eVGA GTX 980 Ti SC+ GAMING ACX 2.0+ (twin fans, slight overclock, backplate, quieter/more pwr than ref)
eVGA GTX 980 Ti SC GAMING ACX 2.0+ (twin fans, slight overclock, quieter/more pwr than ref)
eVGA GTX 980 Ti GAMING ACX 2.0+ (twin fans, no overclock, quieter, possibly more power draw)
eVGA GTX 980 Ti GAMING (reference card, so stock cooler, stock clock, stock power draw)
2. If I power the card with a two 6-pin -> 8-pin, as well as 2x Optical Drive SATA power -> 6-pin?
eVGA GTX 980 Ti SC+ GAMING ACX 2.0+ (twin fans, slight overclock, backplate, quieter/more pwr than ref)
eVGA GTX 980 Ti SC GAMING ACX 2.0+ (twin fans, slight overclock, quieter/more pwr than ref)
eVGA GTX 980 Ti GAMING ACX 2.0+ (twin fans, no overclock, quieter, possibly more power draw)
eVGA GTX 980 Ti GAMING (reference card, so stock cooler, stock clock, stock power draw)
I know that power draw when using only two 6-pin is right on the edge, that's why I'm considering option 2. But is option 2 able to handle the SC/SC+ versions? Let me know your inputs, even if you think that this is overall a bad idea. I just got my Mac Pro, and would love to get the very best solution without modifying PS cables. Lowest noise level, best performance and lowest power draw, where's the sweet spot?! Thanks a lot.
EDIT: According to this: http://techreport.com/review/28685/geforce-gtx-980-ti-cards-compared/5 the SC (not +) uses slightly less power than the ref at idle, and slightly more than ref at load. (But also performs better)
Can you help me choose? Should I worry about too much power draw even if we're talking about a couple of watts? Thanks again
EDIT 2: I could also go with the ACX 2.0+ version without SC? I don't knoooooowwww... Put it in the list above..
