How to choose a gaming PC power supply?

✓Wattage: calculate total component consumption (GPU + CPU + peripherals) and add 20–30% headroom. 650W covers most gaming setups.
✓80 PLUS: Bronze = 82%+ efficiency, Gold = 87%+, Platinum = 90%+. Gold is the best value in 2026.
✓Modular vs fixed: modular PSUs (detachable cables) simplify cable management and improve airflow in the case.
✓Reliable brands: Seasonic, be quiet!, Corsair, EVGA, Fractal Design. Avoid unknown budget brands for this critical component.
✓Warranty: a quality PSU comes with 5–10 year warranty — a sign of reliability.
