Mining rig dual server PSU's functionality info needed !!!

[jiri.lhotsky]

Hey guys, I’m building my first 12 GPU rig with the use of two server PSU’s. 1st PSU powering the motherboard & CPU (through a 260 watt PICO) and 6 GPU’s, 2nd PSU powering another 6 GPU’s. I need to ask the more experienced of you about one crucial thing - the proper procedure of turning on and off the rig aka the PSU’s powering the GPU’s. To my knowledge, the second PSU powering ONLY the GPU’s can be powered on (manually) BEFORE the first PSU (with the connected motherboard). And it needs needs to be powered off (manually) AFTER the first PSU. In other words, the GPU’s on the second PSU needs to be powered all the time while the system is running and it DOES NOT HARM neither the GPU’s nor the motherboard if the 6 GPU’s are powered from trhe second PSU while the rest of the system (motherboard etc.) is shut off. Can you please confirm or comment? Many thanks!
