Ryzen 9000 · data reviewed 2026-11-10
Ryzen 9 9900X is 12 cores and 24 threads on AM5. Gaming plans it at 120 W (Default TDP). The power-limit profile uses 162 W (PPT, derived). With a Radeon RX 9070 XT, the gaming total is 481 W and the minimum size is 650 W.
These open a store search for that wattage class. Prices stay on the store. Disclaimer.
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.
| GPU | Board power | Gaming load | Minimum | Both at the limit |
|---|---|---|---|---|
| GeForce RTX 5060 | 145 W | 322 W | 450 W | 364 W · 500 W |
| Radeon RX 9070 XT | 304 W | 481 W | 650 W | 523 W · 700 W |
| GeForce RTX 5090 | 575 W | 752 W | 1,000 W | 794 W · 1,000 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 DDR5.
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.
Gaming plan for the Ryzen 9 9900X: 120 W at its default tdp, 304 W for the Radeon RX 9070 XT at rated board power, and 57 W of platform allowance. The total is 481 W. Minimum size 650 W. Efficiency size 1,000 W.
With a GeForce RTX 5060, the gaming total is 322 W and the minimum is 450 W. The same CPU with a GeForce RTX 5090 is 752 W, minimum 1,000 W. The CPU did not change. The graphics card did.
The power-limit profile with a Radeon RX 9070 XT is 523 W, minimum 700 W. That is both parts on their limits at once. PPT 162 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.
