First, Thank you very much Nando4 for all your work. I've been reading a lot on eGPU since i bought my X220 in january and never thanked you for your time and work.
Been messing with my GTX 660 ti recently. I was planning to go on holiday with my setup as usual (Seasonic 520 M12II, PE4L 2.1b and good old GTX 660ti), but i encountered a problem with my PSU, it was making scratch noise and the laptop would crash on gaming, meaning the PSU was dead.
So I decided to try and make something out my old Xbox 360 203w PSU. After some quick soldering, i'm pretty satisfied with the result :
Test went smoothly and everything is working fine so far. I did a quick benchmark with my Lenovo X220, on 3D Mark 11 :
specs :
Core i7 2640m
Memory : 8gb Corsair Vengeance PC15000 CAS 10
SSD OCZ Nocti mSata 120gb
Gainward Geforce GTX 660 ti (base model)
Now, i want to make an enclosure with easy mounting for the graphic card, because i swap it between my main computer and my laptop, don't have enough money to buy another one.
