By "5" side pc drive," he might just mean optical drives that fit into a
5" bay. I'll hazard an answer.
The standard connector for ATAPI optical drives (and PATA hard drives)
is the 4-pin "molex" connector. That's in reality a really imprecise
name, but here's what it looks like:

That connector serves two DC voltages, 5 and 12 VDC. The standard 3.25"
floppy drive power connector is the same pinout, but in a narrower
connector, but that should be fairly obvious from a brief examination of
a power supply.
