2nd question) now, lets say your motherboard has an 8 pin CPU power connector, but your PSU has a 4 pin CPU power connector. will you still be able to use your computer?

 if you post your psu model# someone might be able to help you.... otherwise you gonna get ... "i think so" all day.. secondly i havent bought a psu yet that didnt have a online resource site to help with these questions.

google .. its your friend.  

Yes and yes.

IIRC, 8 pin EPS 12V connectors can fit into a 4 pin ATX socket. You may have to google around for the exact answer, but I think (note: think) that all you have to do is plug in half of the EPS heads (left or right half of the connector).

Secondly, you can buy some adapters that enable you to turn your PSU into an EPS 12V compliant PSU (4 pin to 8 pin).
