external gpu lenovo c540

[TheWelshScot]

hi im looking to use an external gpu for my lenovo aio c540,  there is a open slot for the mini pcie on the board but that cable goes to hdmi and as far as im aware there isnt a hdmi input on this computer, is there a workaround for this that someone can help me with?

There's 3 kind of "beast" eGPU adapters, wich should you use depends on the ports aviable in your AIO.

As I can see in the pictures you have 2 NGFF m.2 ports, probably 1 for the wifi and the other for the m.2 NVME/SSD drive.

You plug the connector that is in the last picture in any of the NGFF slots, the HDMI side connect to the main body of the "beast".

The motherboard have too a 4x PCI-E port, don't know what it is for, but **MAYBE** you can use some USB 1x PCI-E riser cable like in the mining rigs to add the eGPU instead of the "beast" eGPU, you maybe want to try this first as these USB risers are dirt cheap now,.

Remember in both methods you'll need a 450w PSU to feed the GPU and drill a hole to get the cable out of the AIO chassis.

Another thing to be aware is that the "biggest" GPU recomended for the i3-3240 is the GTX 1050 (NOT the ti model), otherwise you will have CPU bottleneck, but looking prices maybe is more cost effective to buy a used RX 570 than a GTX 1050, just be aware that the RX 570 never gona run at 100% with your i3

Hope you post your results, because I saw these kind of eGPU on laptops, but never in AIOs.
