White 16-pin to dual 8-pin GPU power cable with braided sleeve and clear combs

BFKK

BFKK 12VHPWR 16-pin to dual 8-pin GPU power cable 14 inch white

SKU CH-MW7N-W3BK7

A 14-inch white extension cable converts a 12VHPWR 16-pin GPU connector to dual 8-pin PSU plugs for up to 450 W

  • ColorWhite
  • PCIe 5.0 16-pin supports RTX 4070 / 4070 Ti / 4070 Super
  • Dual 8-pin connectors deliver up to 450 W peak power
  • 16 AWG tinned copper wire ensures stable voltage transmission
  • 14-inch length plus four acrylic clips keep builds tidy
  • Flexible nylon-braided sleeve avoids sharp bends and overheating

Purpose and compatibility

This BFKK cable adapts a native 12VHPWR 16-pin graphics-card connector to two standard 8-pin PCIe power plugs. It is built for RTX 4070, 4070 Ti, 4070 Super, 5070, 5080 and 5090 cards that already use the 16-pin interface. Builders whose GPU retains dual 8-pin sockets cannot use this adapter.

Power delivery limits

The assembly is rated for continuous output between 400 W and 450 W with a peak of 450 W over the 16 AWG tinned-copper conductors. PCIe 5.0 signalling is supported, but any card or power supply demanding more than 450 W through this connector exceeds the cable’s specified capacity.

Build and cable management

Alloy copper terminals and a high-density nylon braid reduce heat at the plug and improve flexibility compared with stiff factory cables. Four transparent acrylic comb clips are included to align the 14-inch runs cleanly inside compact cases. The fixed length leaves no slack for routing behind large motherboard trays or distant PSU bays.

Highlights

  • PCIe 5.0 16-pin supports RTX 4070 / 4070 Ti / 4070 Super
  • Dual 8-pin connectors deliver up to 450 W peak power
  • 16 AWG tinned copper wire ensures stable voltage transmission
  • 14-inch length plus four acrylic clips keep builds tidy
  • Flexible nylon-braided sleeve avoids sharp bends and overheating

Questions about this item

Should I pick the 14-inch white version or another length for my RTX 4070 build?

This cable is offered in a single 14-inch white configuration, so there is no alternative length or colour to choose from.

What does the 450 W peak rating mean when the cable is installed in my system?

The 450 W peak rating indicates the maximum power the dual 8-pin to 16-pin assembly can deliver to an RTX 4070-class GPU without overheating the connectors.

Does the PCIe 5.0 12VHPWR interface limit the power I can draw through the dual 8-pin plugs?

The 12VHPWR connector is rated for the 400 W to 450 W range this cable supports, so the interface does not cap the output below that level.
