NVIDIA GeForce GTX 1070 power connector: what does it need?
The NVIDIA GeForce GTX 1070 needs 1× PCIe 8-pin from the power supply. At about 150 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.

ATX 3.x advice
Any competent modern power supply with the right cable handles this card. ATX 3.x is optional at this power class.
Safety notes
- 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 1070' on the DEDICATED 1070 page (single spec column; identity confirmed by 'NVIDIA CUDA Cores = 1920' and 'Standard Memory Config = 8 GB GDDR5'). Rows under 'Thermal and Power Specs:': 'Graphics Card Power (W)' = 150 W; 'Recommended System Power (W)' (footnote 4) = 500 W. Cross-confirmed against the '1070' column of the combined 1070/1070 Ti page (20180603052334), which also reads 150 W / 500 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.
