Hi all!
Lets say the PSU doesn't push enough amps for the graphic card, what could happen?

(eg. card needs 35 amps but the PSU supplies like...29)

The PSU would probably just shut down if it is a solid unit. If not, it could take all your components with it.

Ok you have 4 real possible outcomes here:

1: The card pulls the power it needs from the rail and really pushes the PSU but gets what it needs
2: The card tries to pull the power it needs and your PSU explodes trying to provide it
3: You PSU can't do it and shuts off
4: Your machine runs, but will shut off or crash every time you try and run a game or 3d app.
