power arduino uno from pc

hi guys! i would like to pull 9v and 1A from my pc into my arduino uno, or at least whatever i can that can power an LED strip and not too much that the arduino cant handle it, is it possible to plug it into say, the 4 pin peripheral power cable?

What PC has 9v available? You could get 5v off a peripheral socket and apply it directly to the 5v pin.

5v pin on the arduino itself?

Yes.

They advise against it, but a PC power supply is surely as kosher as you need! I imagine it would keep the system cool as well.......
