I'm trying to work out how to power a threadripper multi-gpu workstation. Looks like the CPU can pull 800W and the cards 400W apiece, so that blows past the 1600W limit on the most expensive ATX PSU I can find (a Corsair one).
The options seem to be downclock/power limits or fewer GPUs. There might be something from the world of server power supplies, where form factor is fine but acoustics probably aren't. Difficult to search for too.
So how does two PSU's working together work in practice? E.g. plug one into the motherboard and the other into the PCIE cables and arrange for them both to start together somehow. I remember reading something about them disagreeing on the value of ground so one pushes current into the other. Don't want to kill the system through ignorance.
Thanks!
