PISKEKAT 16 Pin to 2x8 Pin GPU Power Cable 13 Inch Black

SKU CH-CK54-C998D

A 13-inch PCIe 5.0 12VHPWR extension cable converts a 16-pin GPU connector to dual 8-pin PSU plugs, supporting up to 450 W for RTX 4070-series cards

  • Product typeServer
  • Designed for RTX 4070 series GPUs with 16-pin connector
  • Dual 8-pin female connectors deliver up to 450 W peak power
  • 16 AWG tinned copper wire ensures stable voltage transmission
  • High-density braided sleeve provides flexible routing in tight spaces
  • Alloy copper terminals resist heat and maintain secure connection

16-Pin GPU Power Cable for RTX 4070 Series

This 16-pin extension cable connects a GeForce RTX 4070, 4070 Ti or 4070 Super graphics card to a power supply that provides two 8-pin PCIe connectors. It is built with 16 AWG tinned copper conductors and alloy terminals for stable current delivery up to 450 W peak. The 13-inch length suits compact server or workstation builds.

Practical Limits of the PCIe 5.0 12VHPWR Interface

The cable supports 400 W to 450 W continuous output with a 450 W peak rating, matching the power envelope of the listed RTX 4070 series cards. Its 16 AWG wires and tinned terminals reduce resistance and heat at the connector. The flexible braided sleeve eases routing but the fixed 13-inch length cannot be shortened or extended without replacing the cable.

Check Your PSU and GPU Compatibility Before Ordering

Verify that your power supply offers two native 8-pin PCIe ports; adapters or daisy-chained connectors are not recommended for this power level. Confirm the graphics card uses the 16-pin 12VHPWR connector found on the RTX 4070, 4070 Ti and 4070 Super models. Measure the routing path inside your chassis to ensure the 13-inch cable reaches without strain.
