Three CPU pairings
Same platform each time: two memory modules of the CPU's generation, one NVMe drive, three fans, no pump. Gaming uses the CPU's base power. The ceiling puts the CPU on its package limit and the GPU on rated board power.
| CPU | Gaming load | Minimum | Efficiency size | Both at the limit |
|---|---|---|---|---|
| Ryzen 5 9600X a 65 W six-core gaming CPU | 192 W | 300 W | 400 W | 215 W · 300 W |
| Ryzen 7 9800X3D the current 120 W gaming CPU most builds are compared against | 247 W | 400 W | 500 W | 289 W · 400 W |
| Ryzen 9 9950X a 170 W sixteen-core CPU at its stock 200 W package limit when both are maxed | 297 W | 400 W | 600 W | 327 W · 450 W |
Connectors and spikes
6 GB GDDR6. Graphics Card Power: 70 W, from the vendor. These figures are the reference design. A partner card can raise the power limit and change the plug.
GeForce RTX 3050 6 GB is rated 70 W. No supplementary power connector; slot power only. The connector budget covers the rating, with little room above it.
This card is specified without an auxiliary plug, so it has to live on the slot. There is no 12V-2x6 excursion to plan for.
The vendor does not publish a separate in-game average. The gaming estimate uses rated board power.
NVIDIA's required system power is based on a PC configured with a Core i9-10900K. A lower rating may work depending on the system. The Core i9-10900K is an older reference system. Treat the figure as NVIDIA's floor for that PC.
