Exp gdc psu problem


Sep 23, 2016
Hello, I have recently got an exp gdc v8 for my hp Pavillion laptop and I have connected everything as said but don't why my psu is not working properly. I'm using 300w psu and it works when I checked, but when I connect all together from my pcie to exp then the psu is not running it's just numb like that not supplying power to exp gdc. I made sure all the wires are connected properly for several time but still I'm facing the same problem.

Can anyone help me!!
