A PSU is not a place to save money. Cheap power supplies fail catastrophically and fry your whole PC. Here's how to pick a reliable one.
**80+ Bronze**: 85–88% efficiency, cheaper ($60–80), acceptable heat.
**80+ Gold**: 90%+ efficiency, $80–120, less heat, longer lifespan.
**80+ Platinum**: 92%+ efficiency, $150+, rarely needed for home use.
Gold is the sweet spot for builds over $800. Bronze is fine for budget builds.
Modular vs semi-modular vs non-modular
**Non-modular**: All cables hardwired, cheapest, messy case wiring.
**Semi-modular**: Some cables detachable, $20 extra, cleaner.
**Fully modular**: All cables detachable, best cable management, $30–50 extra.
Best budget PSU: Thermaltake Toughpower (~$80)
650W, 80+ Bronze, semi-modular. Reliable, good cable management. Most popular budget option.
