SKU CH-ARPS-3P88S

Connects RTX 4000 series or RTX 3090Ti 16-pin GPU to three 8-pin PSU cables, 300 mm sleeved with combs for clean routing

  • Product type12VHPWR PCI-e 5.0 16Pin (12+4) to Triple 8-Pin GPU
  • Delivers 600W to RTX 4000 series GPUs via 16-pin connector
  • Triple 8-pin design fits PSUs up to 1300W without adapters
  • 300mm length with included combs enables tidy cable routing
  • 16AWG wires wrapped in triple-layer sleeving resist heat and wear
  • Premium black sleeving improves airflow and gives a clean build aesthetic

Compatibility & Connector Type

This extension cable connects a 12VHPWR 16-pin (12+4) GPU socket to three standard 8-pin PCIe power plugs. It is built for RTX 4000 series cards and the RTX 3090Ti that use the native 16-pin connector. The 300 mm length suits typical mid-tower layouts.

Power Supply Requirements

Verify that your power supply provides three separate 8-pin PCIe outputs or cables rated for the combined load. The assembly uses 16 AWG conductors specified for 600 W delivery and is validated for supplies up to 1300 W. Ensure each 8-pin run comes from an independent rail or cable where possible.

Sustained Load Behaviour

The triple-layer sleeved 16 AWG wires maintain stable voltage under continuous 600 W draw without the voltage drop seen on thinner extensions. Included cable combs keep the three leads spaced for consistent airflow during long gaming or compute sessions.

Questions about this item

What comes in the box and do I need to buy any extra cable combs?

The package includes one 16-pin to triple 8-pin GPU power extension cable measuring 300mm and three 12-pin cable combs, so no additional combs are required.

Which graphics cards is this 12VHPWR extension designed for?

It is built for RTX 4070, 4080, 4090 and 3090Ti models that use the 16-pin (12+4) power connector.

What does the 600W rating mean when the cable is installed in my system?

The 16AWG wires and triple-layer sleeving are rated to deliver up to 600W to the GPU, matching the PCIe 5.0 12VHPWR specification for supported RTX 4000 series cards.
