Black 18AWG ATX 12V 4-pin CPU power Y-splitter cable, 20cm long with locking connectors

SMUGDESK

SMUGDESK ATX 12V 4Pin CPU Power Y Splitter 18AWG 20cm

SKU CH-WE3A-88386

Splits one 12V 4-pin CPU power connector into two female ports using 18AWG wire and 20cm length for stable motherboard power expansion

  • Converts one 4Pin CPU port into two female connectors
  • 18AWG copper wire delivers stable 12V power under load
  • 20cm length enables tidy internal routing and airflow
  • Locking connectors resist vibration-induced disconnection during operation
  • Expands CPU power for DIY builds and hardware upgrades

ATX 12V 4Pin CPU Power Splitter

This ATX 4Pin P4 CPU power Y-splitter cable converts a single 4Pin female port into dual female interfaces for desktop internal power expansion. It solves the problem of insufficient CPU power ports on power supplies for DIY PC assembly and hardware upgrades. The 20cm length offers flexible wiring space inside the computer chassis. Suitable for mainstream desktop ATX motherboards with 4Pin P4 power interfaces.

18AWG Copper Wire and Locking Connectors

Adopted 18AWG high-quality copper wire delivers stable 12V power supply with excellent electrical conductivity to reduce voltage drop under load. Precision molded locking connectors provide a firm connection to avoid power disconnection caused by chassis vibration. These features ensure stable power output for motherboard components and help maintain good airflow inside the PC case.

Standard 4Pin P4 Interface Limitation

This cable is only compatible with standard 4Pin P4 CPU power interfaces and not 8Pin EPS connectors. Buyers needing to power 8Pin EPS motherboard sockets cannot use this adapter. Do not exceed the rated current load of the cable and confirm your power supply output specification before installation to ensure safe operation.

Questions about this item

Will the 18AWG wire need replacement after long-term use?

The 18AWG copper wire is built for stable 12V delivery; inspect connectors periodically for wear from chassis vibration, but the cable itself has no scheduled replacement interval.

What limit appears first when the splitter runs two devices continuously?

The combined current draw must stay within the 18AWG cable's rated capacity and the power supply's 12V output spec; exceeding either causes voltage drop or shutdown.

How much heat does the 20cm splitter generate inside a closed case all day?

With 18AWG conductors the resistive loss is minimal at normal CPU loads, so the cable adds negligible heat and does not disrupt internal airflow.
