⚡ Power your rig with sleek simplicity — no PSU Molex needed!
This 12-inch black sleeved adapter cable converts a 3-pin fan header into a 12V 4-pin Molex power source, enabling direct power to water cooling pumps and other 12V peripherals from modern high-output motherboard fan headers. Designed for clean builds and efficient power delivery, it eliminates the need for traditional PSU Molex connections while ensuring safe, RoHS-compliant operation.

Works as advertised!
Works as advertised. Molex to 3-pin. You don't have fan speed control since it's 3-pin just like it says.

Adequate power 👌🏼
This worked great! I connected it to a Noctua silencer cable and then to my video card exhaust fan. Plenty of power to my fan without issue.

No issues
Working as expected.

Works as designed
Does what it's supposed to. Only bought this for my in-laws older system that has standard molex fans on the CPU heat sink

Perfect cable to fix fan

Meh.. it works
Gets the job done but cheaply made. The shrink tubing on the fan header side came off the first time I tried to connect it to the motherboard. I was able to slide it back on there and just avoid messing with it. Poor quality control when manufactured. It still works so I'll keep it.

Exactly what I needed
I ordered this adapter for a computer I'm building, and it's exactly as described and works great.

Not 4 pin
It only connects 2 pins on motherboard to 2 pins on molex.
