12VHPWR Adapter Cable 600W

This 600W adapter cable connects a 12+4 pin graphics card to a compatible be quiet! ATX 2.X power supply. It is designed for builders upgrading to RTX 4080 or RTX 4090 models without replacing the PSU. The sleeved black cable handles all cards requiring a 12VHPWR connector.

Dual 12-pin PCIe requirement

The adapter requires two be quiet! 12-pin PCIe connectors on the power supply side to deliver the rated 600W. PSUs lacking these specific native outputs cannot use this cable. Buyers with units that only offer standard 8-pin or 6-pin PCIe ports will need a different solution.

Build integration and cable management

The single-sleeve design replaces a bulky multi-plug adapter, reducing clutter inside the case. It draws power from two 12-pin PSU sockets and merges them into one 12VHPWR plug for the GPU. This frees up routing space compared to standard adapter bundles.
