I am currently mining on my desktop PC (specs below)
I want to add a second GPU but my power supply might not be sufficient, but i do have a second power supply Seasonic M12II 620W.
If i were to add a second GPU through a PCI-E riser, and use my second PSU on that card, would that be a bad idea?
And how should i position the 2nd GPU? Since it might not fit in my case.
Sapphire Radeon NITRO R9 390 8G with back plate
Intel Core i5-4570
ASRock H87 Pro4
WD HDD 2TB
Cooler Master CM 690 III Closed
