I'm curious why you're asking. I assume iGPU refers to the integrated graphics card provided by Intel. My 2015 MBPr also has a Radeon 370X. I USED TO believe it was an impressive video card until I read the specs on the newer/larger cards that are needed to achieve a minimum of 90 FPS for VR, and to be perfectly honest, the difference on white paper is completely out of control. Completely out of control.

hmmm, very interesting. I'll make a barrel plug then. To make one, I need a 5.5mm x 2.5mm DC male. I'm going to go ahead and assume 5.5mm x 2.1mm DC male simply won't fit and/or work, though I would delighted to be told I'm wrong. I'm not sure why I thought the barrel plug was only necessary if I were not using an external desktop PSU. Thank you for your help, Dschijn!

hmmm, how do I power the akitio via 12V? figured I missed something!

UPDATE: interestingly, the same items "PCI to PCI Bridge" are not showing up on my macbook pro 2015.

thank you for replying! https://www.dropbox.com/s/m09gbaraxc8s86p/power.jpeg https://www.dropbox.com/s/s43qj1ge0wvjmyw/screendmanager.png the second link is the device manager on my mac pro (not my macbook pro) that is showing that "error 12" though I'm not sure I saw that on my macbook pro. I'll check and update this. Any ideas? Thanks for you help. -Justin

Hi everyone, I have an Akitio Thunder2 enclosure with the Radeon R9 Nano seated and an external power supply powering the R9 Nano. The gfx card's fan is spinning after I plug in the thunderbolt cable to my Macbook Pro Retina 15 inch. The external (750w) PSU is on and powering the gfx card and I have a thunderbolt cable plugged into the Macbook Pro, but neither booting into Bootcamp (windows 10) or nor El Capitan results in anything being displayed to the monitor I have connected through an HDMI cable to my gfx card. What am I missing here? My PSU is 750w so I'm pretty sure it's properly powering the gfx card. The fan is spinning on the gfx card and stops when I unplug the thunderbolt cable from the computer. I'm sure I'm missing something, can anyone help? The plan was that if this doesn't work in any way, then I was going to just eat the cost of getting a motherboard + cpu + case to build a windows machine. Oh, I should mention this is mainly to power my HTC Vive for development. Thanks!!!
