Noooo! I missed it! Ahg. Out of stock already.
Use a server PSU. There are 2400w platinum ones that are like $160.
The Problem with server PSU is that you can only use it for GPU and not for the risers. unless there is a way ?
Use 6-pin risers and Pico with server PSU, no ATX is needed. MB runs 14 GPU with the use of m.2 adapter right out of the box with nvOC, too bad it's not available on Newegg now.
