I've recently bought a new DVD Drive and i need to get these cables. I think the first is a Serial ATA or something, dunno what the 2nd one is, an adaptor of some kind?

The second is a molex to S-ATA power conversion cable. You wont need the second one unless your power supply only has molex adapters on it.

The first one is in fact a S-ATA cable to connect it you your motherboard.

First cable is the SATA cable that connects your drive to the motherboard, second one is for connecting to the power supply blocks.
