There is no such thing as PCI power supply. Case power supply can supply power to your PCI-E ports by means of 4, 6 and 8 pin connectors. It's especially true for new cards where PCI-E power is required to operate.

Anyway, there are couple ways to test pins. One of them is to buy computer power supply tester. Second is cheaper is you have multimeter... You can test each pair of pins, required voltage is standardized and can be found in internet.

Are AGP and PCI the same?

No, they are completely different. PCI is a general purpose card interface, AGP is specifically for video cards. Most often you will see an older machine that has one AGP slot and several PCI slots. Both PCI and AGP are out of date, you won't see any new motherboards or computers with AGP, and PCI is in 'legacy' status, that is, PCI slots are only included on motherboards to support older cards that the owner might have. The modern slot is PCI-e (which is incompatible with the older PCI)
