Split power and extend reach

This Y-splitter turns one 4-pin Molex connector into two female ports, letting you power an extra drive or fan from a single supply lead. The same cable also works as a straight extension when only one device needs the extra length.

Practical limits of Molex

The 18 AWG copper conductors carry the current the connector is rated for, but voltage drop grows with every added inch and every extra device on the chain. Keep the total run short and avoid stacking multiple splitters on the same rail.

8 inch cable headroom

At 8 inches the cable reaches across a typical mid-tower chassis without slack, yet it runs out in full-tower builds or when routing behind a motherboard tray. Builders needing longer runs or more than two branches will need a different solution.

Questions about this item

How many devices can I run from one Molex connector using the MLX-Y splitter?

The Y-splitter turns a single 4-pin Molex male connector into two female connectors so you can power two drives or fans from the same supply lead.

What does the 18 AWG copper wire mean for power delivery inside my case?

18 AWG copper handles the typical currents drawn by hard drives optical drives and case fans without measurable voltage drop over the short 20 cm length.

Will the 4-pin Molex interface on this cable work with my modern power supply?

Yes the standard 4-pin Molex pinout is unchanged so the splitter plugs directly into any supply that still provides Molex leads.
