GPU 12VHPWR Extension Cable

This BFKK sleeved extension converts a single 16‑pin 12VHPWR PCIe 5.0 male connector into three standard PCIe 8‑pin plugs. It is built for RTX 40‑series cards such as the 4070 Ti, 4080 and 3090 Ti that draw up to 600 W through the new connector.

Check PSU connectors and wattage

Verify that your power supply provides three native PCIe 8‑pin outputs and is rated at 1000 W or higher as suggested for the target graphics cards. This cable is an extension only and must not be plugged directly into the PSU. It is not compatible with the 12‑pin connector found on RTX 30‑series Founders Edition models.

16 AWG tinned copper with pre‑installed combs

The 16 AWG tinned‑copper conductors and alloy‑copper terminals support the full 600 W rating without voltage drop. White and black sleeving and factory‑fitted cable combs keep the three branches tidy inside the case, reducing clutter and improving airflow around the GPU power zone.

Questions about this item

Does the 12VHPWR PCIe 5.0 male to 3x PCIe 8-pin extension come with cable combs or must they be purchased separately?

The extension includes pre-installed cable combs so no separate purchase is needed for cable management.

Should I choose a different version for an RTX 3090 versus an RTX 4080 when using this 16-pin 12VHPWR extension?

This cable is designed for RTX 40 series cards such as the 4070 Ti and 4080; it is not suitable for the 12-pin RTX 30 series connector.

What does the 600 W rating on the 16 AWG tinned copper extension mean when powering an RTX 4080 in a real build?

The 16 AWG tinned copper conductors and alloy copper terminals support up to 600 W, matching the 12VHPWR specification for stable high-load delivery to the GPU.
