Short .3m braided splitter cable with 12+4 pin male plug and dual 8-pin female connectors

SMUGDESK

SMUGDESK 0.3M 16AWG PCIe 5.0 12VHPWR 12+4 Pin Male to Dual 8Pin Female Braided Power Splitter Cord

SKU CH-KAB2-BVPKG

A 0.3 m PCIe 5.0 12VHPWR 12+4 pin male to dual 8-pin female braided splitter cable for RTX 40 and RTX 50 series GPUs

  • Thick 16AWG copper core reduces voltage drop and heat under full GPU load
  • PCIe 5.0 12VHPWR 16Pin plug fits RTX 40 and RTX 50 series cards
  • One-to-two splitter adapts new 12VHPWR port to dual 8Pin PCIE for older PSUs
  • Full braided sleeve protects wires from abrasion and improves case airflow
  • Short 0.3m length keeps wiring tidy without blocking fans or heatsinks

Power Splitter for RTX 40 and 50 Series

This 0.3 m cable converts a single 12VHPWR 12+4 pin male connector into two 8-pin PCIe female ports. It lets you power RTX 40 and RTX 50 series graphics cards from an older modular PSU that only has dual 8-pin GPU outputs. The short length keeps internal wiring tidy and away from fans or heatsinks.

16 AWG Wire and PCIe 5.0 Standard

Heavy 16 AWG oxygen-free copper conductors reduce voltage drop and heat during sustained full-load operation. The plug follows the PCIe 5.0 12VHPWR 16-pin specification for a secure fit on compatible GPUs. Total cable reach is 0.98 ft, so the PSU must be close enough for both 8-pin connectors to reach without strain.

Check PSU Connectors and Clearance

Verify your power supply provides two separate 8-pin PCIe GPU cables, not a single daisy-chained lead, to handle the current safely. Confirm the 0.3 m length spans the gap between your PSU cable ends and the card’s 12VHPWR socket without pulling tight. Ensure the braided sleeve can route cleanly behind the motherboard tray or along the case channel.

Questions about this item

Is the 0.3 m length right for a compact build with a dual 8-pin PSU?

The short 0.3 m braided cable keeps routing tidy, avoids blocking fans or heatsinks, and reaches dual 8-pin PSU ports in most compact cases.

What does the 16AWG rating mean for an RTX 40 or 50 series card under full load?

16AWG oxygen-free copper reduces resistance and heat during peak power draw, lowering the risk of connector melting or wire softening on high-wattage GPUs.

Does the PCIe 5.0 12VHPWR 12+4 pin male plug work with my existing dual 8-pin PSU cables?

The splitter converts the 16-pin 12VHPWR connector to two standard 8-pin PCIe female ports, letting you power new RTX cards from an older modular PSU.
