Black sleeved 12VHPWR 16-pin GPU power cable 70 cm with combs

BFKK

BFKK 12VHPWR 16-pin GPU power cable 70 cm 600 W

SKU CH-QHF5-J6J1Q

Connects RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards to ATX 3.0 modular power supplies using 16 AWG tinned-copper wire rated for 600 W

  • Delivers up to 600 W through a single 12VHPWR cable
  • 16 AWG tinned copper wire ensures stable voltage transmission
  • 70 cm length with four combs keeps routing tidy
  • PCIe 5.0 12+4 pin connectors fit RTX 3090 Ti 4070 Ti 4080 4090
  • Nylon braided jacket protects wires inside the case

PCIe 5.0 12VHPWR cable for RTX 3090 Ti and 40 series

This 70 cm internal power cable carries up to 600 W between an ATX 3.0 modular supply and graphics cards such as the RTX 3090 Ti 4070 Ti 4080 4090. It replaces multiple legacy connectors with a single 16-pin 12+4 link. The cable is intended for builders moving to the newest GPU power standard. It is not for systems whose power supply lacks a native 12VHPWR output port.

16 AWG tinned copper with nylon braid and four combs

Each end terminates in a male 12VHPWR 16-pin connector built from alloy copper contacts. The 16 AWG tinned copper conductors are thicker than standard 18 AWG wire and aim to deliver stable voltage under load. A nylon-braided jacket protects the bundle while four included combs keep the sleeving aligned for a tidy routing path inside the case. The fixed 70 cm length suits typical mid-tower layouts but may restrict routing in larger enclosures.

Verify your PSU has a native 12VHPWR port before

This cable connects only between two 12VHPWR sockets; it will not work with older 12-pin RTX 3090 cards or supplies that provide only 8-pin PCIe outputs. No adapter is included. Confirm that your modular power supply lists a 12VHPWR header and that your graphics card requires the 12+4 pin input. Buyers needing to convert from 8-pin or dual 8-pin sources cannot use this product.

Questions about this item

What does the PCIe 5.0 12VHPWR interface cap in practice?

The cable is rated for up to 600 W output over the PCIe 5.0 12VHPWR connection.

What does the cable physically need to fit or mount?

It requires a modular PSU with a 16-pin 12VHPWR port and a GPU with a 12+4-pin female 12VHPWR socket.

How is it installed and what step do people get wrong?

Plug one 16-pin end into the PSU 12VHPWR port and the other into the GPU 12+4-pin socket; the common mistake is using it with a 12-pin RTX 3090 connector instead of the required 12+4-pin.
