SMUGDESK 4Pack PCIe 6Pin Female to Dual 8Pin (6+2) Male Power Extension Cables

SKU CH-83P9-FW91K

Converts each 6-pin PCIe port into two 8-pin (6+2) connectors for multi-GPU power supply setups

  • Converts a single 6-pin port into two 8-pin (6+2) connectors for multi-GPU power
  • Works with standard modular and non-modular ATX power supplies and mainstream graphics cards
  • Four-cable pack suits mining rigs, multi-GPU gaming builds and large PC upgrades
  • Reinforced connectors and heavy-gauge wiring provide secure, stable power delivery
  • Extension design improves cable routing flexibility for cleaner case builds

Multi-GPU Power Expansion

This four-pack of PCIe 6-pin female to dual 8-pin (6+2) male extension cables converts a single power supply port into two graphics-card connectors. It is designed for builders assembling multi-GPU gaming rigs, workstations or cryptocurrency mining systems that require additional power outputs. Each cable adds flexible reach for cleaner internal routing.

Sustained Load Reliability

Heavy-gauge wiring and reinforced connectors maintain stable voltage delivery across both 6+2 pin branches during continuous operation. The design supports the steady current draw typical of mining workloads and extended gaming sessions without overheating or voltage sag. Secure terminal crimps resist loosening from vibration or thermal cycling.

Straightforward Installation

Plug the 6-pin female end into the modular PSU cable and attach each 6+2 pin male end to the graphics card; the split occurs at the cable so no extra adapters are needed. Builders must verify their power supply can handle the combined wattage of both GPUs on a single rail. The 6+2 pin format fits both 6-pin and 8-pin GPU sockets.

Questions about this item

How much additional heat or power loss should I expect when running these 6-pin-to-dual-8-pin cables continuously in a mining rig?

The cables use heavy-gauge wiring and reinforced connectors to minimise resistance, so heat and voltage drop stay low even under sustained multi-GPU loads.

What must my power supply already provide for these four cables to work?

You need four available 6-pin PCIe ports on a standard modular or non-modular ATX power supply.

Will the 6+2 pin male ends fit an older graphics card that only takes a 6-pin connector?

Yes, the 6+2 design splits so the 6-pin portion plugs directly into legacy 6-pin GPU sockets while the extra 2 pins hang clear.
