Short braided splitter cable with 16-pin male and dual 8-pin female connectors

SMUGDESK

SMUGDESK 0.3M 16AWG PCIe 5.0 12VHPWR 16Pin to Dual 8Pin Power Splitter Cord

SKU CH-K532-0M5VY

Connects RTX 40 and RTX 50 GPUs to dual 8-pin PSU cables using 16AWG wire in a .3 m sleeved assembly

  • 16AWG thick wire cuts voltage drop and heat under full GPU load
  • PCIe 5.0 12VHPWR 16-pin male fits RTX 40 and RTX 50 series cards
  • One 16-pin male splits to two 8-pin PCIe female ports for power-source expansion
  • Full braided sleeve protects wires from abrasion and improves internal airflow
  • Short 0.3 m length keeps chassis wiring tidy and avoids airflow blockage

Purpose-built GPU power adapter

This 0.3 metre 16AWG splitter converts a PCIe 5.0 12VHPWR 16Pin male connector into two 8Pin PCIe female ports. It targets builders running RTX 40 or RTX 50 series graphics cards on power supplies that only offer dual 8Pin GPU outputs. The short length keeps internal routing clean and avoids airflow obstruction.

Sustained-load behaviour

Heavy-gauge 16AWG oxygen-free copper conductors reduce resistance and voltage drop when the GPU draws peak power during extended gaming, rendering or AI workloads. The braided sleeving protects wires from friction heat and prevents insulation softening or connector melting that thinner cables can suffer under continuous high-current operation.

Pre-installation checks

Verify that your power supply provides two independent 8Pin PCIe cables rated for the graphics card’s total power draw. Confirm the 12VHPWR 16Pin male plug on this adapter matches the GPU’s native socket exactly. Ensure the 0.3 metre reach suits your component layout without putting tension on either connector.

Questions about this item

Does the 16AWG wire stay cool when the RTX 40 or 50 GPU runs at full load all day?

The 16AWG oxygen-free copper core lowers resistance and voltage drop, reducing heat build-up during sustained peak power draw.

What power supply connectors must I already have to use this 12VHPWR splitter?

Your modular PSU needs two free 8-pin PCIe output ports to plug into the splitter's female ends.

Will the short .3 m length fit cleanly alongside my existing PSU cables in a tight case?

At .3 m the cord avoids slack that blocks airflow, letting it sit neatly beside older cable runs without tangling.
