Vszerda 8-Port PWM Fan Hub Power Splitter Adapter, Dual Molex, 40cm Cable

SKU CH-DPN1-NGDJZ

Expands a single PWM header to eight fans, powered by dual Molex with 40 cm cable and self-adhesive mount

  • Expands one PWM header to eight fans
  • Dual Molex power supports 12 V 2 A per channel
  • PWM speed control for 4-pin fans
  • 3-pin fans run at full speed automatically
  • 40 cm PWM cable and self-adhesive mount included

8-Port PWM Fan Hub for High-Density Builds

This internal power cable expands a single motherboard PWM header into eight fan connections. It targets enthusiasts who run multiple chassis or CPU coolers and need centralised speed control. The hub draws 12V power directly from the PSU through dual Molex connectors, removing the current load from the motherboard header. Builders with crowded fan layouts gain a single control point without exceeding header limits.

Dual Molex Power and 40cm Signal Cable

The adapter requires two free Molex 4-pin leads from the power supply to deliver up to 2A per port across all eight channels. A 40cm PWM cable links the hub to the motherboard, carrying the control signal and one RPM sense line. Because only the red-marked header passes a tachometer signal, that port must host a PWM fan for speed regulation to function. Four-pin fans obey the PWM curve; three-pin fans run at full voltage continuously.

Self-Adhesive Mounting and Per-Port Capacitance

A self-stick pad lets installers secure the PCB to a flat surface inside the chassis, keeping cables tidy and the board hidden. Each of the eight outputs includes a dedicated capacitor to smooth voltage spikes and protect connected fans. The bundle contains no software or additional controllers; operation is purely hardware-based through the motherboard fan header. Builders who need independent speed profiles per fan or more than eight ports will require a separate controller solution.

Questions about this item

What is the maximum combined current the hub can supply to all eight fans?

The hub supports up to eight 12 V fans drawing 2 A each, powered from dual Molex connectors.

How much heat or noise does the hub itself add when running all day?

The PCB includes a capacitor on every fan output for stable power delivery, but the hub itself has no moving parts and generates negligible heat or noise.

Which motherboard header and power connectors must already be present for this hub to function?

One 4-pin PWM fan header for the red CPU-fan port and two free Molex 4-pin connectors from the PSU are required.
