NVIDIA GeForce GTX 1080 Ti power connector: what does it need?
The NVIDIA GeForce GTX 1080 Ti needs 1× PCIe 8-pin + 1× PCIe 6-pin from the power supply. At about 250 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.
Power connector
1× PCIe 8-pin + 1× PCIe 6-pin
Reference power input.
GPU board power
250 W
Vendor TGP/TBP — a conservative ceiling, not typical gaming draw.
PSU minimum (typical build)
550 W
Assumes a 125 W-class CPU + standard accessories.
PSU comfortable (typical build)
650 W
Standard headroom for spikes and future room.
Board-partner note
NVIDIA reference design (shown); many partner cards use 2x 8-pin.
ATX 3.x advice
A classic multi-8-pin quality PSU works for this card. An ATX 3.x unit is still a sensible buy for its transient-load headroom, but it is not required.
Safety notes
- Run a separate PSU cable to each 8-pin input on the card rather than one daisy-chained (pigtail) cable, keeping per-cable load conservative.
- 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.

How to check this figure
NVIDIA has retired this card's product page — every live URL now 404s or redirects to a current-generation landing page with no specifications, and the live compare tool covers only 16-series onward. The figures are therefore cited from an archived capture of NVIDIA's own page. Matched on Full-specs modal titled 'GEFORCE GTX 1080 Ti' (single spec column; identity confirmed by 'NVIDIA CUDA Cores = 3584' and 'Standard Memory Config = 11 GB GDDR5X'). Rows under table heading 'Thermal and Power Specs:': 'Graphics Card Power (W)' = 250 W; 'Recommended System Power (W)' (footnote 4) = 600 W.. The link uses the archive's raw-bytes form because the archived page's original scripts otherwise redirect a browser back to nvidia.com.
