Context

Understanding recommended psu

Recommended PSU is a numeric spec measured in W. On this metric, lower values are generally better — smaller, lighter, thinner, or less demanding usually translates to a more comfortable or more efficient product. When comparing two products, focus on the percentage gap rather than the raw delta: a 200-unit lead means something very different at the low end of the range than at the high end. Pay attention to the unit, too — manufacturers sometimes quote peak or burst figures that are not sustained in real-world use. Cross-check the published number against independent measurements where possible, especially for performance and battery claims. Finally, remember that a single spec rarely tells the whole story; the Mars Score weighs recommended psu together with the rest of the spec sheet so one outlier doesn't distort the verdict.

This matchupROG Astral RTX 5090 OC's 1200W is roughly 20% more than GeForce RTX 5090's 1000W (a 200W gap). Lower is better here, so GeForce RTX 5090 takes the lead in real use.
