It is extremely small, enables the use of cheap and portable DC power supplies and contains the elusive ability to daisy-chain Thunderbolt devices, with the eGPU itself being the first device in the chain. So this is the highest power graphics card that I can run with my laptop based on my CPU with the least bottlenecking possible?

Things like CS:GO and Minecraft wont have any problems, more demanding titles will likely stutter heavily or may not run at all. Before I tell you the results, it’s worth noting that if you use an nVidia GPU series GTX 400 or newer, you can actually power the internal screen of your laptop with it. These blue light filtering glasses reduce the amount of blue light entering your eyes from computer or phone screens to avoid eye fatigue.With the laptop disconnected, idle power drawn from AC/Mains was ~2W because the PSU fan continued to run even with no load. The use of NV graphics card users please drive control panel in PhysX in the graphics settings to the GPU operation can significantly improve performance. you can still let the internal monitor on for secondary screen, but for games only use the external one. If you use your notebook display, please make sure it comes with In tel (R) H D graphics and connected above GTS450 as NVIDIA graphics. If you see a blank screen on your laptop screen as well as your external monitor, it’s possible that your BIOS is locked from the manufacturer.

Oddly the PSU specs state there are two separate 12V rails, but there is only one rail and it can drive up to 27 amps which is more than enough for the Thunderbolt card, charging a laptop, and a ~200-watt class GPU like a GTX 1080. I did some benchmarking of my Laptop Studio with RX570 egpu daisy-chained *after* the Lenovo TB4 dock. The drivers for the HD 7770 are very up to date (one of the reasons I went with AMD rather than nVidia).Boltoway, can you please share more pictures, as I couldn’t see where is the pci slot to mount gpu on this module? I just like to get comfortable at a proper desk with an ergonomic keyboard, mouse, and all my stuff which stays put. But this does not make a difference when using the EXP GDC or the adapter because it's still passing it through an x1 which the slot on my laptop. With the GPU running at peak load with a mild overclock and 120% power target and no laptop charging, I saw the power meter at AC/Mains peak at ~270 watts.
