Not sure what cord I need | Antec 500W

[Shadow_Riv]

I am adding a second HD, the Samsung Spinpoint 1TB. I have the HD and the 18" Serial ATA 150/300 Cable but I'm not sure what cable I need for the PSU.

I'm thinking maybe it should be Serial ATA power adapter? It's just that when I opened the comp. none of the free cords fit the HD. :\

If it's a SATA drive then you will need a SATA power cable. You can use a Molex to SATA converter if your PSU does not have one.
