20 Pin vs 24 Pin Power Supply

I have an Antec power supply with a 20 pin connector for the main power to the motherboard. I noticed that the newer motherboards require a 24 pin power supply connection.

Will the older power supply work with a newer motherboard (with an adapter of some sort)? There is a great deal on a mobo/CPU combo at Fry's today that I was thinking about, but having to purchase another supply would kill any savings.

I wanted to put THIS motherboard in my older Antec Sonata case (with its Antec power supply).

Am I heading for trouble with this? Is there any reason for not doing this?

Been a while since I dealt with any hardware (as if it wasn't obvious ;) ).

Thanks for any advice!

I have a 24-pin mATX motherboard (Asus P5L-VM 1394) running on a Antec 300w 20-pin PSU. You don't need an adapter -- just plug the 20pin into the 24pin. Just make sure you plug in the 4-pin (2x2) 12V connector, and you should be fine.
