LP4 to SP4 Power Adapter

The EN-Labs MOLEX-LP4-SP4 is a 15 cm internal power cable that converts a large 4-pin Molex LP4 male connector into a small 4-pin SP4 female connector. It uses copper conductors to carry 5 V and 12 V power. The short length keeps cable routing tidy inside compact chassis.

Floppy Drive and Legacy Adapter Power

This adapter suits builders adding floppy drives or SP4-equipped expansion cards to a power supply that only offers LP4 plugs. It is not for systems that lack a free LP4 connector or for devices that require a different pin arrangement or voltage layout.

15 cm Cable Length

The fixed 15 cm length determines how far the SP4 device can sit from the LP4 source. Measure the internal routing path before purchase to confirm the reach is sufficient for your build.

Questions about this item

What comes in the box and do I need any extra cables or tools to connect a floppy drive?

The package contains the 15 cm adapter with a Molex LP4 male plug on one end and an SP4 female socket on the other. No extra cables or tools are required; plug it directly into an existing LP4 power lead.

Which version should I pick if my power supply only has large 4-pin Molex connectors?

This single model converts a large 4-pin LP4 connector to the small 4-pin SP4 format used by floppy drives and some adapters, so it is the correct choice for that situation.

What does the 5 V / 12 V rating mean when the cable is installed in a PC?

The four copper wires carry both 5 V and 12 V rails from the power supply through the LP4 plug to the SP4 socket, delivering the voltages a floppy drive or SP4 device expects.
