They recommend 500W because 1. it needs to power CPU/Mobo too, and 2. because people buy shitty PSUs that are rated higher than what they can actually perform. That card will maximally draw 300W alone, but probably even less than that.

The thundertek input is only made for 30-40w? Not sure if it would handle a bigger power brick... The safest bet is probably going with some other PSU, especially if you want to use a graphics card that require more than 75w. Maybe it's possible to run a GTX 750 in the enclosure with no modifications, it shouldn't draw that much power, but anything bigger than that, you surely need a bigger PSU.

So to understand this correctly, if you use Windows 8.1, you don't need any egpu setup software?

I was under the impression that there was no problems with errors such as 12/43, TOLUD, UEFI/MBR mode, PCI Reset Delay from reading this guide: http://forum.techinferno.com/diy-e-gpu-projects/6723-%5Bguide%5D-14-asus-g46vw-gtx780ti%4010gbps-tb1-thundertek-win8-1-a.html It is however quite short on details.

Sorry for not making this clear. I was talking about the problems you brought up such as error 12/43, TOLUD, UEFI/MBR mode, PCI Reset Delay and performance.

Didn't this guy basically have no trouble with any of this? http://forum.techinferno.com/diy-e-gpu-projects/6723-%5Bguide%5D-14-asus-g46vw-gtx780ti%4010gbps-tb1-thundertek-win8-1-a.html Sorry for perhaps being clueless, but I'm quite new with eGPUs, but am considering getting a thundertek.

Unfortunately I am not sure how to figure out where such a point would be on the board. But a picture of it got posted here, maybe some of the unused connectors can be used for this? http://forum.techinferno.com/attachments/diy-e-gpu-projects/11586d1399813091-thunderboltadapter1.jpg

Could you give some more details on how to make this work? If you read the instructions from the Thundertek, it says it powers on itself when it is attached to a thunderbolt port. Could this be used to power on the ATX PSU?
