NVIDIA Founders Edition 12-pin GPU Power Adapter

16 contacts: 12 power/return and four sideband sense; exact supply-end wiring is PSU-family specific.

CLASSIFICATION: Internal power cables. Identify protocol, direction, pinout and exact cable revision before connection.

Interface and capability

Standard / protocolNVIDIA Founders Edition proprietary 12-pin GPU power
Endpoint / pinout12-pin 2×6 GPU-side connector, fed by two PCIe 8-pin (6+2) plugs; this proprietary RTX 30-series Founders Edition interface is not 16-pin 12VHPWR/12V-2x6.
Capability / limitsAdapter is intended only for listed NVIDIA Founders Edition RTX 30-series cards and the supplied cable. There is no general 12-pin cable length/certification class.
Certification / lengthStandards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology.

Compatibility & handling

  • Connect both complete PCIe inputs using the included or manufacturer-approved adapter. Never mistake this 12-contact proprietary GPU end for a 16-contact 12VHPWR plug; PSU modular ends remain model-specific.
  • Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
  • Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
