SKU CH-KX70-6JKEJ

A 17 cm male-to-female 12VHPWR extension cable compliant with ATX 3.0 and PCIe 5.0 for RTX 3080 and 3090 Ti graphics cards

  • ATX 3.0 and PCIe 5.0 compliant for safe GPU power delivery
  • Male-to-female 12VHPWR extension adds routing flexibility inside the chassis
  • Compact 17 cm length keeps cable management tidy in small-form-factor builds
  • 16-pin 12+4 connector fits RTX 3080 and 3090 high-power graphics cards
  • Heavy-duty wiring maintains stable current under sustained gaming loads

12VHPWR Extension for RTX 3080 and 3090

This male-to-female cable extends the 12VHPWR connection on graphics cards such as the RTX 3080 and 3090. It follows the ATX 3.0 and PCIe 5.0 specifications for 16-pin 12+4P power delivery. The 17 cm length is intended for compact chassis where the stock cable falls short. Builders needing a longer reach for full-size towers will need a different cable.

ATX 3.0 compliant connectors with 17 cm routing

Heavy-duty wiring and secure 12+4P plugs maintain stable current under sustained load. The short 17 cm span keeps excess wire out of the airflow path, aiding tidy routing in small-form-factor builds. The male-to-female layout plugs directly into the existing PSU cable without adapters. Installers who require right-angle or 90-degree plugs for tight side-panel clearance are not served by this design.

Standardised pinout enables direct GPU connection

The cable uses the official 12VHPWR pin arrangement, so the graphics card detects the link without extra configuration or software. No driver, firmware or utility is bundled because the hardware handshake is handled by the connector itself. Users expecting RGB lighting, sleeved extensions or a modular daisy-chain kit will not find those features here.
