Black braided 0.3m cable with 16-pin male plug splitting to two 8-pin female connectors

SMUGDESK

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

SKU CH-SYMK-GXK3T

0.3 m 16AWG PCIe 5.0 12VHPWR 16-pin male to dual 8-pin female splitter delivers stable power to RTX 40 and RTX 50 graphics cards with braided sleeving for tidy cable management

  • Thick 16AWG copper handles peak GPU current with minimal voltage drop
  • PCIe 5.0 12VHPWR male splits into two 8Pin PCIe females for modular PSU
  • Braided sleeve protects wires from abrasion and aids chassis airflow
  • Short 0.3m length reduces clutter in compact ATX and MATX cases
  • Gold-plated terminals lower contact resistance for stable RTX 40 and RTX 50 power

Purpose-built GPU power adapter

This 0.3m PCIe 5.0 12VHPWR 16Pin to dual 8Pin splitter cord connects RTX 40 and RTX 50 series graphics cards to modular power supplies that only have native 8Pin PCIe outputs. It is for builders who need a short, tidy link between a 12+4 pin GPU and two standard power-supply cables in compact ATX or MATX cases. The cable does not suit GPUs with legacy 6Pin or single 8Pin power inputs.

Sustained-load behaviour

Thick 16AWG copper conductors carry high current during extended gaming or rendering sessions, limiting voltage drop and line heating that thinner wires would allow. Gold-plated terminals keep contact resistance low over many mating cycles, so power delivery stays stable when the GPU holds boost clocks for long periods. The 0.3m length removes excess slack that could add resistance.

Thermals and cable management

A dense braided sleeve protects the wires from abrasion, aids heat dissipation and keeps airflow clear around chassis fans. The short 0.98ft run prevents cable coils from blocking intake or exhaust paths, helping the case maintain a cooler internal environment. No active cooling or fan is included; the design relies on passive sleeve dissipation and tidy routing.

Questions about this item

How much heat does the 0.3 m 16AWG cable produce when the GPU runs at full load all day?

The 16AWG copper conductors are chosen to minimise voltage drop and line heating even during sustained peak-current operation, so the cable stays cool enough for continuous high-load gaming or rendering sessions.

What power-supply connectors must I already have to use this 12VHPWR 16-pin male to dual 8-pin female splitter?

Your modular power supply needs two free native 8-pin PCIe power outlets; the splitter plugs directly into them and delivers power to the graphics card's 12+4-pin socket.

Will this PCIe 5.0 12VHPWR splitter work with an older graphics card that still uses 8-pin power inputs?

No, the male connector is a 12+4-pin 12VHPWR plug made exclusively for RTX 40 and RTX 50 series cards, so it cannot mate with an 8-pin GPU power socket.
