I'm building my first PC and I'm running into an issuw with no video output to the monitor. I know the monitor is good - I just unplugged it from my old PC.
I have a ASRock FM2A55M-DGS motherboard and a Corsair CX430M power supply. I do not have anything connected to the ATX 12V power connector (4-pin ATX12V1). The manual says to connect an ATX 12V power supply to this connector, but when searching the ASRock website it seemed to indicate that all that power that is needed is supplied from the ATX Power Connector (24-pin ATXPWR1).
There were no connectors that came with the power supply that would connect to the ATX 12V power connector.
So, my question is... do I need to get some connector for the ATX 12V power connector to make the video work? If not, what else could be causing this?
