Molex-to-Fan Power Splitter
This 12 V adapter converts a single four-pin Molex connector into four three-pin or four-pin fan headers. The 27 cm black-sleeved cable uses 22 AWG wiring and is intended for desktop power supplies that lack enough native fan plugs. It draws power directly from the PSU so every attached fan runs at full voltage. No PWM signalling is passed through the splitter.
Builders Needing Extra Fan Ports
Suits anyone adding multiple case or radiator fans to a supply with spare Molex leads but insufficient three-pin or four-pin headers. Not for users who require motherboard-controlled fan curves, because the cable does not forward PWM speed signals. Buyers wanting voltage regulation or software fan profiles should look at a powered hub or a motherboard splitter instead.
Simple Plug-In Installation
Push the Molex end into any free peripheral connector on the power supply, then attach up to four fans to the three-pin or four-pin sockets. The keyed plugs prevent reversed insertion. The only common issue is expecting automatic speed control; the fans will spin at 12 V continuously unless the motherboard or a separate controller regulates them.

Questions about this item
Will this 12V splitter work with my existing power supply that only has a 4-pin Molex connector?
Yes, the cable connects a single 4-pin Molex output from your PSU to four 3-pin or 4-pin fan headers, so you can power multiple fans from one connector.
Can I connect older 3-pin fans to the 4-pin ports on this 27cm cable?
The four output ports accept both 3-pin and 4-pin fan plugs, so your older 3-pin fans will fit and receive power without any adapter.
How do I confirm the 22AWG wires are delivering power correctly after I plug in the fans?
When the system is on, each connected fan should spin immediately; if a fan stays still, reseat its plug into the splitter port to ensure a firm connection.
