As long as your power supply also has the 4 pin 12VATX power connector that should plug on the socket at right portion of motherboard in above photo, your set up should work. You might only encounter a problem once you plug in a discrete video card that draws power mainly through the motherboard.

Answer 2

Assuming you don't have a power-sucking video card, you should be fine. You'll need to tell us the watts of your current power supply, but I suspect it will be more than enough.

Btw, check if your power supply has a 4-pin input that could be used with the 20-pin. 20+4 = 24 :) If the motherboard says it needs it, you'd better have it.

Answer 3

Your power needs with that setup are quite modest. Any decent 300-350 watt power supply should run your system fine. If the system boots ok with the 20 pin connector, then you should be fine.
