Thank you sshantt for the very kind words
You're very brave trying to cram in the EVGA FTW's considering the recent news about them catching fire
The SLI cable issue can also be solved by doing a 90 degree bend on the riser cable and then undoing it. I will be trying that on prototype 2
Might need a longer riser cable, until Li Heats super skinny risers are out, which will be plug and play in my case. The have the same standoff positions as my existing Adexelec ones.
The
FSP700-80UEPB PSU is a beast of a PSU. It has 4 x 12v rails rated at 16A each. Being as quiet as it is, even under decent load you may be able to accomplish what you're after.
Lets say you reserve 1 x 12v (16A) rail, which is 192Watts for motherboard, cpu, ram, hdd's, fans etc ...
You have 3 x 12v (16A) rail, which is 576 Watts for the GPU's. Which should be enough to even power Titan XP's, which are 250Watts each.
Those 3 rails can be split among 4 x 8 pin PCIE connectors.
Unfortunately stock standard the FSP PSU is a server grade PSU which means it has multiple 8 PIN CPU connectors and only 1 PCIe connector. These need to be changed.
I'm in talks with FSP about getting "gamer" versions of this PSU made, which will come with the correct 8 PIN PCie plugs. I do not know yet if this PSU will be included with the case, it might drive the price way too high, due to the cost of that PSU being around $180 USD itself.
The second revision is also going to support FlexATX as I'm aware some users will want to build ITX systems in this case and potentially single GPU solutions as well. So now bundling in a PSU that a large proportion of users may not want will deter interested parties.
Another possibility is to use 8pin CPU to 8pin PCIe adapters, just be mindful of the clearances as there isn't much room to hide away cabling. Everything is on show in this case so cabling must be on point.
