What PSU for the Ryzen 7 5800X3D?

Ryzen 7 5800X3D 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.

These open a store search for that wattage class. Prices stay on the store. Disclaimer.

Same CPU, three graphics cards

Each row is two memory modules, one NVMe drive, and three fans. Only the GPU changes, so the difference between rows is the card plus nothing else.

How to read the two CPU numbers

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 5800X3D need with a Radeon RX 9070 XT?

Gaming plan for the Ryzen 7 5800X3D: 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 5800X3D 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 5800X3D 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.
