SMUGDESK

SMUGDESK 4Pin CPU Power Y Splitter Extension Cable 20CM 18AWG

SKU CH-WJE9-9SQRE

A 20 cm 18 AWG Y-splitter turns one 4-pin CPU power connector into two for dual-port motherboards

  • Expands one CPU power port to two
  • 18AWG copper reduces voltage drop under load
  • Standard ATX P4 12V pinout fits mainstream boards
  • 20cm length keeps case wiring tidy
  • Locking terminals resist vibration during long runs

One-to-two 4Pin CPU power splitter

This SMUGDESK Y-splitter turns a single ATX P4 12V male connector into two 4Pin female ports, letting a power supply feed two motherboard CPU power sockets. It is built for DIY builders and technicians who need an extra 4Pin CPU connection without replacing the PSU. The 20cm length keeps internal routing tidy and supports airflow. Locking buckles on each connector resist vibration in long-running systems.

18AWG conductors and current headroom

Thick 18AWG tinned copper wires lower resistance so the cable delivers stable voltage even when the CPU draws heavy current. It comfortably handles typical dual 4Pin motherboard configurations within the PSU channel rating. The design runs out of headroom if the combined load exceeds what the single PSU 4Pin rail can safely supply; the supplier warns against exceeding that rated load.

ATX P4 12V pin-out constraint

The splitter follows the standard ATX 12V P4 pin assignment, so it works only with traditional 4Pin P4 CPU power interfaces. It is incompatible with 8Pin EPS CPU power ports and cannot be adapted for them. Buyers must verify their motherboard uses 4Pin CPU sockets and that the PSU 4Pin rail can cover the total current demand.

Questions about this item

Will this 18AWG splitter handle the power draw of an older motherboard that still uses a single 4Pin P4 CPU connector?

The 18AWG tinned copper conductors are rated for high-current output, reducing voltage drop and heat so the older board receives stable power through the single male plug.

How can I verify the splitter is delivering stable power to both 4Pin female ports after installation?

Check that each locking buckle clicks securely into the motherboard headers, then monitor CPU voltage readings in BIOS or hardware monitoring software for steady 12 V rails under load.

Does the package include any extra mounting hardware or do I only get the 20cm Y-cable itself?

Only the 20cm 1-to-2 Y splitter cable is supplied; no screws, ties or additional adapters are included.
