4-Way Molex IDE 1 to 4 3Pin Fan Splitter Cable, 4Pin Molex D Plug to 3Pin Cooling Fan Y Splitter Power Cable 12V for PC PSU

This Molex IDE to 4 x 3Pin fan splitter cable is a practical power expansion accessory for desktop computer DIY builders. It adopts a 1-to-4 split design, which uses a single 4Pin Molex D connector from your power supply to supply power to up to four 3Pin cooling fans simultaneously.

Many motherboards only provide limited fan headers. If you want to install multiple chassis fans, radiator auxiliary fans or ventilation fans, this splitter helps you draw steady 12V power directly from the PSU without occupying motherboard fan interfaces.

Manufactured with high-conductivity copper wire and multi-insulated cable material, the splitter guarantees stable power delivery. Reinforced connectors maintain tight connection to prevent intermittent power loss caused by loose plugs during long-term operation.

Easy plug-and-play installation with no drivers or complicated setup required. Just connect the Molex plug to your power supply, then attach your 3Pin cooling fans to the branch terminals.

Important Note: This cable only provides 12V power supply. It cannot transmit fan speed signal and does not support PWM speed control. All connected fans will run at constant speed. Please calculate the total current of all fans to avoid overloading the Molex power line. Perfect for PC assembly, chassis airflow upgrades, server cooling and computer hardware modification projects.
