Ruth's sister 4 Pin Molex IDE Male to 4P ATA Female Power Cable 200mm

SKU CH-HEDD-4PWZZ

Converts a standard Molex connector to a floppy-drive power plug, adding a 200 mm reach for legacy drives or CF-card adapters

  • Connects legacy floppy drives to modern PSUs via 4-pin Molex to 4P ATA adapter
  • 200mm length fits compact builds and tight drive bays without cable strain
  • Powers CF-card storage replacements for DOS and Win98 systems lacking native small 4P connectors
  • Supplies auxiliary power to high-draw add-in cards such as graphics or 1394 controllers
  • Single-cable solution replaces missing small 4P ports on current power supplies

Legacy drive power adapter

This 200 mm cable converts a standard 4-pin Molex connector from a power supply into a 4-pin ATA female plug used by floppy drives and compact-flash adapters. It targets builders maintaining vintage DOS or Windows 98 systems, soft-router appliances, or industrial hardware that still relies on legacy power interfaces. The short length keeps cable routing tidy inside compact chassis.

Connector gender and pinout

The male Molex end plugs into any existing PSU peripheral lead while the female 4P ATA end mates with the small floppy-style power header on the target device. No active electronics are present so the adapter simply passes 5 V and 12 V rails through unchanged. Polarity follows the industry-standard Molex-to-floppy pin mapping.

Build integration notes

One Molex connector on the PSU is consumed to provide a single legacy power tap, freeing the motherboard’s sole floppy header for other uses or eliminating the need for a second floppy lead. The 200 mm reach suits typical ATX or micro-ATX layouts without excess slack. Systems requiring multiple floppy-style devices will need additional adapters or a PSU with native floppy connectors.

Questions about this item

What does the 200mm length mean once the cable is routed inside a case?

The 200mm run connects a standard Molex output from the PSU to a small 4P floppy-style connector, giving enough slack for a typical ATX chassis without excess cable clutter.

Which interface standard does the 4P ATA female end follow, and what does that limit in practice?

The small 4P female end matches the legacy floppy-drive power pinout, so it can only supply the 5 V and 12 V rails that older floppy drives, CF-card adapters or certain expansion cards expect.

What clearance or mounting points does the cable need to fit?

It requires a free standard 4-pin Molex socket on the power supply and a matching 4-pin floppy-style header on the target device; no brackets or screws are involved.
