Would it be possible to take a 300W ITX PSU and use it as a dedicated GPU supply?
I'm pondering this question for an ultra SFF project. I know a 150W graphics card is rated for 75W power draw off the 6 pin 12V. The PSU in question has 2 12V rails, each rated at 14 amps. Theoretically, the PSU would have ample supply. In practice however, I'm not sure it's possible.
The setup I'm thinking about would be this: ITX mobo, 160W PicoPSU for the ATX supply, and a possible ITX PSU.
My research has shown that a true dedicated GPU supply plugs into the ATX connector itself, which leads me to think that the 2 supplies are somehow "communicating" maybe? That's why I'm doubtful the stand alone can be done.
Can anybody who knows more about this topic than me check in?
