i've read people have used a 75w pcie only powered graphics card and it works but im not only curious about the actual wattage being used by computer stock.. im also curious as to if this adapter by corsair https://www.corsair.com/us/en/Categories/Products/Accessories-|-Parts/PC-Components/Power-Supplies/ATX12VO-Adapter-Cable/p/CP-8920272 would allow me to use a normal atx12v psu with this motherboard? if that's wrong what use is this adapter for? sorry guys if this seems simple im very new to computers. thanks in advance for any help!
