Setup: Macbook Air2015 with Thunderbolt 2 Connection on OS X 10.10.4 Akitio Thunder2 Nvidia 750 Tisc (One Fan) DellDA-2 Cable: Akitio Egpu 8 Pin to 2 x PCI E 6 Pin Super Low Profile No Latch 1 x Barrel | eBay The Akitio is powered by only the barrel plug The Monitoris plugged into the GPU. The set-up is working, and the card is recognized, but my FPS in games is about the same as my HD6000 I used the Script provided by Goalque: Mac OS X discussion The card uses about 75 watts, but a few people have reported the stock PSU is powerful enough to get the card started, but not if it gets under load. I'm not sure if plugging in the DellDA-2 is any different than the PSU included with the Akitio since I'm just plugging in the barrel plug. Do I need a powered riser? Also, when I look at the Nvidia web driver, it says the 750 Ti isn't supported even though its recognized. Is this just a problem with drivers? I don't know what to do!
