Nobody answered my question.
With these 4k PSU setups, its really nice to support so many GPUS, but it looks like you would have to disconnect a large number of cables to take a rig out of service. I'm thinking about building a custom setup with 2 Mother boards, 16GPUs, and one FINKSY 2880 PSU all in one custom case. This way the connection to that case is just power and network.

I did answer your question, did you miss it? Pasting it here just for reference.

@yun999 -- I'm curious about how you use the 4k PSU bundles with open rigs. It seems one PSU would power 4 or more rigs (at 6 cards each). So when you have to take one rig down, what do you do? Disconnect the 9 power cables going to the cards and risers? Or are you rigs set up so you do maintenance in place? I have to move mine to replace a card. Right now the ATX PSU goes with it, so to do maintenance all I have to do is disconnect the 120v AC and the network cable... and its a unit.

I am liking the 4k PSU bundle, just not sure how to deal with it. Or maybe I should build a massive open rig with multiple motherboards and GPUs and treat it all as one unit. LOL!.

While the 4k PSU delivers most of the power for the system (namely, all the cards) each system still needs a mini PSU (basically just a low capacity regular PSU like 450W) which is what you use to turn on/off each system.
The alternative, and what everyone is switching to, is a nanoPSU which powers off of the 4K PSU and has a small on/off switch.

Anyways, no harm in building a custom setup, don't forget to share pics here. Best of Luck.
