System specs

PC: Lenovo B540 23" All-In-One 1080p
CPU: Intel Core i5-3350P, RAM 6Gb DDR3-1600
dGPU: NVIDIA GeForce GT 650M
OS: Windows 10 Home edition 

eGPU hardware (cheap!):

  • US$6 PCE164P-N03 miniPCI-e  eGPU adapter + noname 1m USB cable (5$)
  • eGPU: Zotac GeForce GTX 560 Ti 448 Cores (50$)
  • FPS ATX 600w power unit (40$)
  • cardboard storage box (5$)

Hardware pictures

The idea was to build eGPU 'here and now' from anything that suits. So 




Installation steps

1. The trickiest step: connect USB 3.0 cable to mPCI-e 2.0 port. Lenovo AIO has 2 free ports. Take out USB cable through the vent holes and you're almost there)
2. Connect power supply to the riser card and eGPU. GTX 560 Ti has 2 6-pin power connectors, and it loves Watts! (210W)
3. If you don't have power button , simply connect green and black wires on the 20-pin motherboard connector.
4. Connect eGPU HDMI cable to the Lenovo HDMI-in. You're ready to go.

Starting and configuring

1. Turn on eGPU power.
2. Turn on PC.
3. Follow the Error 43 issue solution, in general steps are:
3.1. Boot up in safe mode, remove all GPU drivers with DDU.
3.2. Boot up without driver checking. 
3.3. Install old driver (368), install newest driver.
3.4 Boot up in normal mode.

Unresolved issues

1. I can't make it work on Lenovo's screen without HDMI-in.
2. Severe FPS drops after constant GFX changing in games. I think it's a lack of memory and mPCIe bandwidth problem.



650M gave 10000 points, 560 Ti gave almost 30000 on the same test.


Well, I used to play Battlefield 3 and 4.
650M managed to provide me with stable 50-60 fps on minimum graphics in 720p.
560 Ti made possible same fps in 1080p with medium-to-high graphics.

I think I've got best results for such a low budget (106$).

Small update:
Recently upgraded to GTX 1070 mini itx: and got 46000 points in same test. Sorry, can't attach screenshot.
BTW got critial issues with system interruptions on latest NVidia drivers, so latest stable version for GTX560 and 1070 remained 390.77.

Hey There,

Thanks for the write up, I will be attempting to do the same to my Lenovo AIO 510 this weekend, replacing the 940mx with a GTX 750ti

Quick one, did you have to disable anything in the bios or Windows beforehand?

Thanks in advance,

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

thnx for feedback! I was surprised by facing Error 43 problem for 5x series. But nothing special, typical solution for this worked out just fine. BTW guys have developed one mouseclick script for that. Will test this soon with upgrading to 1070 😉
