I expect to purchase this motherboard, but am unsure about whether I can

plan to overclock the board or use it for gaming. The cards are likely
to be a modest audio and wifi card, and there will be one or two SATA
hard disks. The audio card is because the onboard audio chip is reported
to be flakey with the Linux OS.


Thank you for your very interesting and informative reply. I did the
best I could to estimate power requirements and came up with 350W. I
suppose 450 Watt power supply could handle it, although it would leave
little breathing room. I suppose one should have a power supply
significantly larger, but since I have a new 450W supply in hand, I'd
like to try using it.

What happens when demand is a bit too much for a power supply? Would
rail voltages begin to drop, or will the supply shut itself down before
that occurs?

You might see some droop if it's on the edge.

If you don't have a monster video card, I doubt it's 350W.

Were you using this one ?
