NVIDIA GeForce RTX 4080 SUPER power connector: what does it need?
The NVIDIA GeForce RTX 4080 SUPER needs 1× 16-pin 12V-2x6 (12VHPWR-compatible) from the power supply. At about 320 W board power, here is what to know before you plug it in.
Recommendations are planning estimates, not electrical or purchasing advice. The hardware figures behind them are vendor-published; your exact board-partner model and build can still differ.

750 W
Standard headroom for spikes and future room.
Board-partner note
Original 12VHPWR 16-pin; 12V-2x6 cables are compatible. FE includes a 3x PCIe 8-pin adapter.
ATX 3.x advice
An ATX 3.1 (or ATX 3.0) power supply with a native 12V-2x6 / 16-pin cable is strongly recommended for this card. It avoids adapters entirely and is specified for modern GPU power excursions.
Safety notes
- Seat the 16-pin connector fully — NVIDIA's instruction is to ensure the plug is fully inserted and seated flush against the receptacle. Partially seated 16-pin connectors are the known cause of melted plugs. Route the cable so nothing forces it sideways at the plug.
- Use the native PSU cable or the adapter supplied with the card. Never chain third-party adapters or extensions on a 16-pin connection.
- Never mix modular cables between different PSU brands or models. The PSU-side pinout is not standardized — a mismatched cable can destroy hardware.
- Do not exceed a cable's rated load with splitters or adapters, and replace any cable with damaged or discolored connectors.
- Before buying, confirm the connector layout and PSU guidance on the official pages of both your exact card model and your PSU — board partners change designs between variants.
