i realize this isnt the place for this but i thought one of you guys may know the answer and save me finding a forum somewhere to ask.. maybe i need to call a psu mfgr?
if i find i need to run a dedicated power supply just for the GPU cards, how does startup/shutdown work? what gets powered on first? mobo then gpus? then mobo off then gpus? or should i have them on a common switch to turn both on / off at once? can the 2 motherboard/psu 'sense' contacts that automate the power on/off be paralleled for both psus to hook to the same 2 contacts?
