Gaming PC power supply: choosing the right PSU in 2026

The PSU is the most underestimated component in a gaming PC. Too weak, it crashes the PC under load; poor quality, it can damage all components.

What wattage PSU for my GPU?

Simple rule: add GPU + CPU TDP, then add a 20–25% margin. Example: RTX 4060 (115W) + i5-12400F (65W) = 180W → 450–500W PSU sufficient.

RTX 4070 (200W) + i7-13700K (125W) = 325W → 650–750W recommended.

80+ Bronze (82–85% efficiency): sufficient for most gaming builds.

80+ Gold (87–92%): recommended for builds over €1,000.

Take action with the comparator: pick your games, budget, then compare PCs.
