Molex to Floppy Power Adapter

This cable converts a 5.25 inch Molex connector to a 3.5 inch floppy drive 4 pin female connector. It is intended for users who need to power a legacy 3.5 inch floppy disk drive from a standard LP4 power supply lead. The package includes two adapter cables and a self-adhesive tape strip for securing the wiring inside a chassis. The product is supplied new and ready for installation.

18 AWG Copper Conductors

Each adapter uses 1007 standard tin-coated copper wire rated at 18 AWG gauge. The short 7.5 inch length including connectors minimises voltage drop and cable clutter in tight drive bays. Passive construction means no active cooling or fan noise is introduced to the system. Power draw is determined entirely by the connected floppy drive and the host power supply capacity.

Sustained Legacy Drive Operation

Under continuous use the adapter simply passes whatever current the 3.5 inch floppy drive requires through the 18 AWG copper conductors. The tin coating on the wires resists oxidation over long periods of intermittent or constant operation. No thermal throttling or performance curve applies because the device contains no active components. Reliability depends on the quality of the host Molex connection and the drive's own power specifications.

Questions about this item

How do I connect the 5.25" LP4 Molex end to my power supply and the 3.5" floppy 4-pin end to the drive without reversing them?

Plug the larger LP4 Molex connector (Connector A) firmly into a free Molex lead from the PSU; the smaller 4-pin female floppy connector (Connector B) keys onto the drive's header — the notch on the floppy plug faces the cut-out on the drive socket.

Will the 18 AWG tin-coated copper wires or the self-adhesive tape need replacement after a few years of use?

The 1007-18AWG copper conductors are rated for continuous use and do not degrade under normal floppy-drive loads; the included self-adhesive tape is for one-time cable routing and does not require periodic replacement.

What is the maximum continuous current the 18 AWG wire can handle before voltage drop becomes an issue on the 7.5-inch run?

At 19 cm length the 18 AWG copper leads add negligible resistance, so the practical limit is the floppy drive's own draw — well within the wire's safe capacity for standard 3.5" FDD operation.
