Ryzen 7 5800X is 8 cores and 16 threads on AM4. Gaming plans it at 105 W (Default TDP). The power-limit profile uses 142 W (PPT, derived). With a Radeon RX 9070 XT, the gaming total is 462 W and the minimum size is 600 W.
AMD's public product page lists Default TDP. Stock Package Power Tracking (PPT) for this TDP class follows AMD's socket default of 1.35× TDP, rounded to the standard step (65W→88W, 105W→142W, 120W→162W, 170W→230W). PPT is a power limit, not a measurement of a game or a render.
Memory in this table is DDR4.
The GeForce RTX 5060 row is the small-card case: the CPU and the platform are a large share of the total. The GeForce RTX 5090 row is the flagship case: the graphics card dominates, and the CPU's base-versus-limit gap matters less until you render on every core.
Questions for this CPU
What PSU does a Ryzen 7 5800X need with a Radeon RX 9070 XT?
Gaming plan for the Ryzen 7 5800X: 105 W at its default tdp, 304 W for the Radeon RX 9070 XT at rated board power, and 53 W of platform allowance. The total is 462 W. Minimum size 600 W. Efficiency size 1,000 W.
How much does the Ryzen 7 5800X add when the GPU is small?
With a GeForce RTX 5060, the gaming total is 303 W and the minimum is 400 W. The same CPU with a GeForce RTX 5090 is 733 W, minimum 1,000 W. The CPU did not change. The graphics card did.
Should I size a Ryzen 7 5800X build for the package limit?
The power-limit profile with a Radeon RX 9070 XT is 499 W, minimum 650 W. That is both parts on their limits at once. PPT 142 W is marked derived. AMD's public product page lists Default TDP. Stock Package Power Tracking (PPT) for this TDP class follows AMD's socket default of 1.35× TDP, rounded to the standard step (65W→88W, 105W→142W, 120W→162W, 170W→230W). PPT is a power limit, not a measurement of a game or a render. Use it for a combined render. A GPU-bound game is the lower row.
