I built my PC this weekend. I have not turned it on yet and I have a couple concerns.

1. When I was screwing the motherboard to the chassis, I initially did not use the screw standoffs because one of the diagrams didn't require it. The standoffs raise the height of the screws so the motherboard does not sit on the chassis. It leaves space under the board.

I fastened about two screws when I noticed the diagram for the other part did include standoffs in its diagram. So I undid the two screws and used standoffs all around. I'm not sure how much contact the motherboard made with the case chassis, and I'm wondering if I caused any damage when the board was temporarily screwed down without the standoffs.

2. I also notice my old power supply had a mode switch for 115V and 230V. My new power supply doesn't have a mode switch at all. How does it know what voltage to select?

Thanks,
Dave

1: You should be OK. Make sure you don't have extra standoffs under the board. Extra standoffs short out boards.

2: Modern active PFC PSUs don't have a voltage switch. Doesn't need one. As long as voltage is between 100 and 240V, it is good to go.
