Can someone clarify the response to the OP's question about having one PSU for the motherboard and the Server PSU dedicated to PCIE adapters for the cards?
I read the reply where someone said they turn on the server pSU 1 second before the main power, but I was wondering if there were opinions on this. I have read other people online say not to do that, but they didn't display a reason why/how it is dangerous.
Thanks
I have a 6 GPU rig with the mobo supplied by an ATX PSU and the PCIe power connectors on each card supplied by an HP server PSU. I leave the server PSU on all the time without issue. The only real requirement is that GPU power be present at the same time
or before the mobo is turned on.
