[Solved] PSU for eGPU and other things (Aorus RX580)
I'm rebuilding my portable DIT case and would like to use one power supply for all the stuff I have in my case. The goals are: reducing the noise level, and freeing up some space in the case taken by power bricks. Right now I'm using separate power bricks for the 4 different devices I have (ethernet router with poe, caldigit ts3, hdd dock, HD-SDI I/O), and a separate AC feed for the eGPU. My idea for an upgrade is ~600W ATX power supply powering everything in my case. All the other devices will be fed from 12V line of the PSU with some step-up/down converters, I have it more or less figured out so it's not an issue here.
The issue is:
I do not always use the eGPU, and sometimes I cannot spare a thunderbolt port just to keep it on. Can I just bypass the on/off control of the eGPU's motherboard and just provide the power to eGPU at all time without having a thunderbolt plugged into that? Or is there a smarter solution, like a power supply that would take 12V DC as an input? (so I will then have a PSU for everything and a 12V one for just the eGPU?)
