12VHPWR GPU Power Cable

This BUCIER cable is a PCIe 5.0 12VHPWR internal power cable designed to deliver up to 600W to compatible graphics cards. It features a 16-pin connector with 12 power pins and 4 signal pins, built to the PCI-SIG specification for ATX 3.0 power supplies. The 16AWG pure copper core and nylon-braided sleeve provide stable voltage and a compact fit inside the case.

For builders upgrading to ATX 3.0 GPUs

The cable suits systems using a native 12VHPWR power supply output to run cards such as the RTX 3090 Ti, 4070 Ti, 4080 and 4090 without adapter clutter. It is not for power supplies that only offer 8-pin PCIe outputs, nor for graphics cards that retain the traditional 8-pin or 12-pin connectors instead of the 16-pin 12VHPWR socket.

600W power rating per PCI-SIG spec

The decisive figure is the 600W capacity validated against the PCI-SIG limit of 9.2A per terminal for a total of 55.2A on the 12V line. If your graphics card draws more than 600W or your power supply lacks a native 12VHPWR port, this cable will not meet the requirement.

Questions about this item

Does the 16AWG copper core and nylon braid on this 12VHPWR cable run cooler than the stock adapter at 600W?

The 16AWG pure-copper core and high-temperature insulation are rated for the full 600W, so heat stays within PCI-SIG limits even under sustained load.

My PSU has native 12VHPWR ports — can I plug this male-to-male cable straight in?

Yes, the cable is a male-to-male design made for ATX 3.0 power supplies with native 12VHPWR outputs.

Will the 12+4 pin connector on this cable fit the 12VHPWR socket on my older RTX 3090 Ti?

The connector follows the PCI-SIG 12VHPWR spec, so it mates with the 12+4 pin socket on the RTX 3090 Ti and newer cards.
