Now when im looking for the power supply is there anything specific I am looking for other than that I need at least 750W to run my computer w graphic card?
Do all power supplies come with the same kind and number of "pins"?
Any suggestions on type of power supply I should get?

you dont need 750w to run a q6600 and a 9800gtx. a good quality 400 or 500w is plenty. here are some psu that will run your system fine. no need to waste soo much money.

IMO the best deal today is:

CORSAIR CMPSU-650TX $59.99 after rebate

Corsair is good for their rebates, unlike some others.

Agree with most of the suggestions here (except the ludicrous 700w-900w suggestions)

Any "Decent branded" PSU in the area of 500-600 will be plenty for the system.

Corsair, Antec, PCP&C, Seasonic
