Hello guys,
I am a complete newbie when it comes to all the eGPU stuff, just had a few hours of studying builds and thinking how to do things. I have a spare MSI R9 390 8G card and was hoping to make it eGPU, to be able to play something in my spare time on my T580. At the moment it is really difficult due to thermal throttling of GPU, CPU. While I managed to undervolt CPU and it works quite well now, I am still not getting any good numbers with dGPU - GeForce 150MX.
So, I've been thinking of disconnecting wifi card inside, using a dongle instead and connecting the mini pci-e EXP GDC.

Now, the card needs quite a lot of power, over 400W when it peaks so I wanted to get atx power supply of 450W.

The question that raised in my head is that I found in EXP GDCs description something like this Power support: 8P interface: 220W max. DC interface: 150W max. Does that mean it will not support a power supply of 400W? If it still would, would hat be everything I need? I am trying to do that low cost mode, hence avoiding TB3 enclosures which cost alot of money imo. I would be really glad if someone could say few words of opinion on that setup.

Thank you
