A short black cable with a 4-pin Molex plug splitting into four 3-pin connectors, two white and two black

Vszerda

Vszerda 4-pin Molex to 2×5 V & 2×12 V 3-pin fan power cable 12.5 cm

SKU CH-HW8N-AM9CC

Splits one 4-pin Molex connector into two 5 V and two 12 V 3-pin fan headers, 12.5 cm long

  • Converts one Molex connector into four 3-pin fan headers for expanded cooling options
  • Delivers two 5 V and two 12 V outputs to match fan speed requirements
  • Colour-coded white and black plugs simplify correct voltage selection
  • 5 cm length fits tidy internal routing in compact cases
  • Lightweight 10 g design adds minimal strain to motherboard headers

Power-adapter cable for case fans

This 12.5 cm cable converts a single 4-pin Molex connector into two 5 V and two 12 V three-pin outputs. It is built for PC builders who need to run multiple 3-pin fans from one Molex header.

Replaces limited 3-pin headers

When a motherboard or fan controller lacks enough 3-pin sockets, this adapter adds four connections without occupying extra board headers. The jump is worthwhile whenever the existing 3-pin ports are exhausted but a Molex plug is free.

Steady voltage delivery under load

Each output maintains its rated 5 V or 12 V line continuously, so fan speeds stay consistent during prolonged operation. The short 12.5 cm run keeps resistance low, preventing voltage drop that could otherwise slow fans over time.

Questions about this item

How much clearance do I need for the 12.5 cm cable and its four 3-pin connectors?

The cable is 12.5 cm long and splits into two white 12 V and two black 5 V 3-pin plugs, so allow enough room for the split and each connector to seat without tension.

Which Molex pin do I use to get 5 V versus 12 V for my fans?

Plug the single 4-pin Molex male into a standard peripheral power lead; the cable internally routes 5 V to the two black 3-pin plugs and 12 V to the two white 3-pin plugs.

Will the 3-pin plugs wear out and need replacing?

The 3-pin connectors are rated for normal internal use; if a plug becomes loose or a wire frays, replace the whole 10 g adapter cable.
