White sleeved 16-pin to three 8-pin PCIe 5.0 extension cable with clear combs

Vszerda

Vszerda 16pin to 3x 8pin PCIe 5.0 Extension Cable 30cm White

SKU CH-CF37-MWEV6

A PCIe 5.0 12VHPWR extension cable with 16AWG tinned copper wire splits one 16-pin connector into three 8-pin connectors for RTX 3090Ti, 4070, 4080, 4090 GPUs.

  • 16AWG tinned copper wire delivers stable 600W power output
  • 12VHPWR 12+4 male to three 8-pin female connectors fits RTX 4090 4080 4070 Ti
  • 30cm sleeved extension adds length while keeping voltage transmission reliable
  • Four acrylic cable combs included for a neat and tidy build
  • PCIe 5.0 specification supports RTX 3090 Ti 4090 4080 4070 Ti graphics cards

Compatibility and purpose

This PCIe 5.0 extension cable connects a 12+4 pin male GPU connector to three 8 pin (6+2) female PSU connectors. It is designed for RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards that use the 12V-2x6 standard. The cable will not fit the 12 pin connector found on the RTX 3080 or 3090.

Sustained-load behaviour

Sixteen AWG tinned copper conductors carry up to 600 W continuously, providing stable voltage delivery during prolonged gaming or rendering sessions. The tinned coating resists oxidation so resistance does not increase over time. Four acrylic cable combs keep the 30 cm run organised and airflow clear inside the case.

Deciding specification

The cable terminates in a 12+4 pin male plug that mates only with GPUs built for the 12V-2x6 interface. If your graphics card uses the older 12 pin connector, this extension cannot be used.

Questions about this item

Does the 16AWG tinned copper wire run cooler than thinner cable when the GPU pulls 600W all day?

The 16AWG tinned copper conductors reduce resistance compared with thinner wire, so less energy becomes heat during sustained 600W loads.

My power supply only has 8pin (6+2) PCIe outputs — will that work with this cable?

Yes, the cable splits one 12V-2x6 male plug into three 8pin (6+2) female connectors that plug directly into standard PSU PCIe cables.

Can I keep my older RTX 3080 and just swap the power cable to this one?

No, the RTX 3080 uses a 12pin connector while this extension is built for 12+4pin GPUs such as the RTX 3090Ti, 4070 Ti, 4080 or 4090.
