Lost on Wiring.

[tampac66]

I have a Antec520W Power supply, and im not sure what i need to wire except for the main power connector to the mother board.

Also, how do i get power and data from my optical drive and hard drive? Were they supposed to come with cords because mine came with only the drive.

Your PSU should have these types of connectors,

In addition to the 24 pin connector, your MB will need either the 8-pin EPS 12V or the 4-pin ATX 12V connector as well.

Your HDD and optical drive, depending on the type, (SATA or IDE), will use either the Serial ATA connector or the Molex connector.

PCI Express connector is for a GPU which your GPU may or may not need

Q2: "Were they supposed to come with cords because mine came with only the drive?"

A: Yes, you need a cable to transfer your data between the MB and the optical drive & Hard drive.
If they didn't come with a cable most motherboards will contain the cords you require in the box. You just need to determine if the HDD and OD are Sata or IDE.

for reference.

If it's the ribbon cable, you need to use a 4-pin molex connector. If it's SATA you use the SATA power connector.
