Vszerda

Vszerda 12VHPWR to Dual 8-Pin 16AWG 30cm internal power cable

SKU CH-1FXY-NYP1W

Connects a PCIe 5.0 graphics card to a power supply using a 12VHPWR plug and dual 8-pin connectors at 16AWG over 30cm

  • ATX 3.0 PCIe 5.0 standard enables 600W delivery
  • 12VHPWR H+ connector with 12 power pins plus 4 signal pins
  • Dual 8-pin PSU side connects to existing power supplies
  • 16AWG conductors handle high current over 30cm length
  • Compatible with RTX 3080 and 3090 TI graphics cards

Connection and standard

This Vszerda cable converts a modular power-supply output with dual 8-pin PCIe connectors into a single 12VHPWR plug that follows the ATX 3.0 and PCIe 5.0 specification. The 12+4 pin layout carries up to 600 W of power plus side-band signals required by the new connector standard. It is built with 16 AWG conductors and measures 30 cm in length.

Who it suits and who it does not

Builders installing an RTX 40-series or equivalent next-generation graphics card on a power supply that only provides traditional 8-pin PCIe outputs will find this adapter fits the requirement. Systems already equipped with a native 12VHPWR header, or those running cards that draw power exclusively through 8-pin or 6-pin connectors, have no use for this cable.

Capacity and headroom

The 16 AWG wiring and PCI-SIG 12VHPWR H+ construction support the full 600 W rating defined for the connector, giving ample headroom for high-end GPUs such as the 3080 and 3090 Ti when used with a compatible power supply. The fixed 30 cm length limits routing options in larger chassis, and the cable cannot supply power beyond the 600 W ceiling or to devices that require a different pin-out.

Questions about this item

My power supply only has 8-pin PCIe connectors — will the dual 8-pin ends of this 12VHPWR cable plug straight in?

Yes, the cable splits into two standard 8-pin PCIe plugs that fit any PSU with those ports.

I still use an RTX 3080 — can this 12VHPWR cable power it safely?

No, the 12VHPWR connector is for RTX 40-series and newer cards; the 3080 requires the traditional 8-pin or 12-pin layout.

After routing the 30 cm cable, how do I confirm the 12VHPWR link is seated and delivering power?

Push the 16-pin plug until the latch clicks, then verify the GPU powers on and shows no connector warnings in its software.
