BUCIER

BUCIER 16-Pin 12VHPWR GPU Cable White

SKU CH-2P8W-JYJGX

White 16-pin 12VHPWR cable delivers 600 W via 16 AWG copper and nylon braid for RTX 4090, 4080, 4070 Ti and 3090 Ti

  • ColorWhite
  • PCIe 5.0 12VHPWR standard powers RTX 3090 Ti, 4070 Ti, 4080 and 4090
  • 16 AWG pure copper core delivers stable voltage for 600 W loads
  • Three-layer nylon-braided construction saves case space and clears side panels
  • Each terminal rated 9.2 A for 55.2 A total 12 V current capacity
  • Male-to-male modular design replaces bulky 12+4 to 4×8 pin adapters

Direct GPU Power Cable

This BUCIER 16-pin 12VHPWR cable connects an ATX 3.0 power supply directly to compatible graphics cards. The white sleeved design uses 16AWG pure copper conductors for stable voltage delivery up to 600W. A single cable replaces multi-connector bundles and reduces clutter inside the case. The 12+4 pin layout follows the PCI-SIG specification for PCIe 5.0 power delivery.

Builders Using ATX 3.0 PSUs

The male-to male modular connector fits power supplies with a native 12VHPWR port and cards such as the RTX 3090 Ti, 4070 Ti, 4080 and 4090. The compact profile allows the side panel to close without interference. Builders whose power supply lacks a native 12VHPWR output or who need to adapt older multi-rail units should look at a different adapter solution.

600W PCI-SIG Certified Delivery

Each of the twelve power terminals is rated for 9.2A, giving a combined 12V current capacity of 55.2A. The cable has been tested to pass the full 600W specified for the 12VHPWR standard. This single figure confirms whether the cable can handle the graphics card you intend to power.

Questions about this item

Is this the 16-pin 12VHPWR cable or the older 12+4 adapter?

This is a single 16-pin 12VHPWR cable with 12 power pins and 4 signal pins, not a multi-plug adapter.

Will 600W through this cable actually run an RTX 4090 without melting?

The PCI-SIG spec rates each terminal at 9.2A for 55.2A total, and the manufacturer tested 600W delivery through the 16AWG copper conductors.

Does the PCIe 5.0 label mean the cable carries PCIe 5.0 data signals?

No, the PCIe 5.0 label refers to the ATX 3.0 power standard; the cable only carries 12V power and side-band sense signals.
