A modest 145 W GeForce card. NVIDIA's 550 W system minimum was written around a Ryzen 9 9950X, not this 65 W CPU.
Gaming total 267 W. Minimum 400 W. Efficiency size 550 W. If both parts sit on their limits, the load is 290 W and the minimum becomes 400 W.

Ryzen 5 9600X base power is 65 W and the package limit is 88 W (derived).GeForce RTX 5060 board power is 145 W.NVIDIA publishes a system minimum of 550 W. NVIDIA's required system power is a minimum for a PC configured with a Ryzen 9 9950X. NVIDIA recommends a PCIe CEM 5.1 compliant PSU. Power requirements can differ with the rest of the system.
WattWise's minimum for the gaming estimate is 400 W. The vendor figure is 150 W higher.Their number is a floor for the reference PC they named. It is not added on top of ours.
GeForce RTX 5060 is rated 145 W. 1× 8-pin, or a 300W or greater PCIe Gen 5 (12V-2x6) cable. The connector budget covers the rated board power.
Do not add a second copy of the board power for spikes. Intel ATX design guide 336521, updated for PCIe CEM 5.1, requires a PSU above 450 W with a 12V-2x6 connector to hold 200% of its label for 100 µs, 180% for 1 ms, 160% for 10 ms, and 120% for 100 ms, at the duty cycles in that table. A card above 75 W may reach 3× sustained power for 100 µs or less. Use a native 12V-2x6 cable rated at least 300 W and seat it fully. Sense pins advertise 150, 300, 450, or 600 W.
Power-limit ceiling for this exact pair: 290 W, minimum 400 W, efficiency size 600 W. That row is a combined render, not a typical game.
