A technician is rebuilding a desktop PC that still uses an older PATA hard drive and a DVD-RW drive. Which 4-pin power connector from the power supply should be plugged into each of these devices to provide +12 V and +5 V?
The 4-pin peripheral ("Molex") connector supplies +12 V on the yellow wire and +5 V on the red wire, with two black grounds. It was the standard power plug for PATA hard drives, optical drives, and some case fans. A 15-pin SATA power connector is used on SATA devices, the small 4-pin Berg connector powers floppy drives, and the 24-pin ATX connector powers the motherboard-none of these are appropriate for PATA or IDE optical drives.
