So I recently decided to try using an eGPU on my laptop just for fun but I've run into a strange problem. (I built my own setup out of parts I had)
My Gigabyte RX580 (which is on the supported cards list) powers down the minute I plug in a thunderbolt cable, or any USB cable for that matter. All lights and fans totally power down. As far as hardware I'm using a generic pcie eGPU card from ebay or something, (I don't know because it came attached to my card when I bought it) my RX580 8gb, a 2018 version of the HP OMEN 15T, (dc0010nr) an old PSU from the 80's or 90's running at 300 Watts, (Which I thought would be more than enough) and an Amazon basics thunderbolt cable which I just bought.
Also the RX580 drivers won't install along side my GTX1050ti drivers and seem to delete themselves off my machine after a little while, but leave the program name and shortcut.
Some things I've tried are different cables, different PSUs and I know all the power cables are plugged in correctly to the GPU and eGPU card.
I pulled the GPU from a working machine for testing to deiced whether I wanted to buy one for my laptop or not.
Any thoughts and suggestions would be greatly appreciated!
