On the ASRock site, I was just looking through an FAQ or something and found this:
Can old style power supply be used for ASRock's Intel platform Motherboards ?
Instead of using the new Intel specified 4-pin connector, ASRock MB still uses the 20-pin power connector. With this implementation, consumers who are migrating from the old computer still can choose to use their old power supply instead of going out to purchase a new one.
So as for power supply it seems good to go. However, I am planning on upgrading my current 160w power supply to something in the 400's in about a month. Would I be able to plug the new supply into this mobo?
