Black sleeved 16-pin male to three 8-pin female PCIe 5.0 extension cable 30 cm with clear combs

Vszerda

Vszerda 16-pin to 3×8-pin PCIe 5.0 12VHPWR extension cable 30 cm 16AWG 600 W

SKU CH-MZY0-S6X64

Extends a 12VHPWR connection to three 8-pin PCIe plugs using 16AWG tinned copper wire rated for 600 W over 30 cm

  • Delivers up to 600 W through 16 AWG tinned copper conductors
  • Extends 12V-2x6 GPU power with 30 cm sleeved cable and 3× 8-pin connectors
  • Compatible with RTX 3090 Ti 4070 Ti 4080 4090 5070 5070 Ti 5080
  • Includes four transparent cable combs for tidy routing
  • 12VHPWR PCIe 5.0 male-to-female adapter for stable voltage transmission

Compatible GPU Power Extension

The Vszerda 16-pin to 3×8-pin cable extends a native 12V-2x6 connection for RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards. It bridges the PSU’s existing 8-pin leads to the GPU’s 12+4 socket without replacing the factory harness. Builders who need a longer reach for clean routing will find the 30 cm length useful. This adapter does not fit the 12-pin connector found on RTX 3080 or 3090 models.

Build Quality And Daily Use

Sixteen AWG tinned copper conductors carry up to 600 W while resisting oxidation over time. The sleeved jacket and four included acrylic combs keep the three 6+2 branches aligned for tidy cable management. A keyed 12+4 male plug seats securely into the GPU, and each 8-pin female end accepts standard PSU cables. The design adds no active components, so signal integrity relies on the existing power delivery chain.

Deciding Specification

The cable is rated for 600 W total output across the three 8-pin connectors. If the graphics card draws more than this figure under load, the extension becomes the limiting factor. Verify the GPU’s maximum board power before installation.

Questions about this item

Does the PCIe 5.0 12VHPWR interface on this cable limit power delivery to 600 W?

The cable is rated for up to 600 W, so the 12VHPWR connector will not deliver more than that in practice.

What clearance is needed for the 16-pin male connector and three 8-pin female ends?

The 30 cm length and included acrylic combs let you route the 16-pin plug and three 6+2-pin sockets in tight GPU bays.

How do I install the extension without melting the 12VHPWR plug?

Seat the 16-pin male fully into the GPU until it clicks, then attach each 8-pin female to the PSU cables; the common mistake is leaving the 12VHPWR latch unlatched.
