Hi, I just succesfully finished a low profile eGPU setup, I decided to share the experience I had. My goal was to make it as portable as possible but still powerful enough to drive the internal 12.5 inch 1366x768 display of my lenovo x220. The parts I used: PE4L 2.1b + EC2C with EC-060A (l x w) 64 x 47 mm Zalman GTX650 low profile max 64W (l x w x h) 150 x 55 x 35 mm Laptop AC adapter 12v 10a 120w TEKO P/3 small plastic case (l x w x h) 160 x 90 x 60 mm M2 nuts and bols Lenovo X220 with 1.37 bios (Series 6, HD3000) USB to USB cable The GTX650 low profile card is very nice for an internal eGPU setup, its very small and draws only 64W max. This means it can draw its power from the pci-e lane, which provides 75W max. No extra connectors on the videocard. Its still powerfull enough to run games at high/ultra on 1366x768. Ofcourse an atx psu is not an option for portability, so a 12V 10A 120W ac laptop adapter is used (2.5 - 5.5mm plug). The initial installation went pretty smooth, the card got detected and the nvidia drivers installed withouth problems. There was no need to change the tolud size or an dstd override. Settings used pe4l: SW1: 1, SW2: 2-3 Settings used bios: PCI express speed -> automatic, PCI express powermanagement -> off. Unfortunatly I couldn't run a benchmark or game for longer then 3 minutes without a bsod or crash. After some research it turned out the card didnt get a clean 3.3v from the pci-e lane. The fix was to run an usb - usb cable from the laptop to the pe4l for 3.3v power. No more crashes and very stable performance :-) Too bad an extra cable is needed though, portability took a small hit there. A few pics of the case and the setup: Some dremel action for the dvi and hdmi port: More dremel action to run the cable and pci-express card through: Drilled m2 holes to mount the pe4l: pe4l mounted on m2 bolts: Up and running: Need to finish the cover plate and paint the enclosure matte black: And a small video I made: Let me know what you think!
