First I'd like to say thank you @Tech Inferno Fan. You're amazing! I think I'll get the GTX 670 and run it with an xbox 360 PSU. I like win 7. My rig has been running rock stable with it. If all goes well, I'll post a small guide.

Hi, My setup x220 i7-2620 8gb RAM Bios 1.39 Win 7 Pro 64-bit PE4L-EC060A (SW1=1, SW2=2-3) 2.1b 16v 70w 4a DC PSU usb-to-usb Evga 750ti Lights D1 and D3 are on and are green and yellow respectively on PE4L. The fan runs at medium speed when I power it up with the adapter and USB and slows down when I plug with expresscard in. It also speeds up really fast for a second after I shutdown the laptop immediately before my laptop turns off. I'm currently stuck on code 12. - Tried to take one of my 4gb RAM out but it still would not work and I do not have another RAM to go below 4gb. - Tried running gpu after sleep and at Windows loadup by F8 method. - Tried DSDT override (via angerthosenear's method - http://forum.techinferno.com/diy-e-gpu-projects/3539-guide-dsdt-override-simultaneous-igpu-dgpu-egpu.html) but I had the blue screen. - Tried uninstalling all video drivers and reinstalling them (Nvidia 347.88 and Intel lastest drivers, win64_152823.exe) I've read of other people with similar setups that did not have problems. http://forum.techinferno.com/diy-e-gpu-projects/7162-%5Bperformance%5D-x16-2-0-desktop-vs-x1-2-0-egpu-gtx770-r9-270x.html http://forum.techinferno.com/implementation-guides/4532-12-lenovo-x220-gtx650%404gbps-c-ec2-pe4l-2-1b-win7-%5Bremko78%5D.html http://forum.techinferno.com/provisional-guides/3208-12-lenovo-x220t-gtx650ti%404gbps-c-ec2-pe4l-2-1b-win7-%5Brhx123%5D.html This is what I see on GPU-Z Any help would be appreciated

From http://forum.techinferno.com/diy-e-gpu-projects/7442-egpu-lenovo-x220t-pe4h-mpcie-pm3n-gtx-750ti.html#post101937 Hey @Riri-Fifi, I have a similar laptop (x220 i7) and I was wondering if you managed to get your setup working? I plan to purchase a 750ti. I want to use an Xbox PSU (like http://forum.techinferno.com/provisional-guides/3208-12-lenovo-x220t-gtx650ti%404gbps-c-ec2-pe4l-2-1b-win7-%5Brhx123%5D.html) to build a eGPU but I wanted to know if you were able to make it work with a normal power source.

I'm a semi-noob planning to build an egpu rig on my lenovo x220 i7 to bring it back to life. Do you have to run a PSU (I'm guessing an ATX) for the GTX 750 TI or can you use an external 12v AC power adapter right onto the PE4L-EC060A board? I want to build an enclosure for the gpu as small as possible
