Common Mistakes to Avoid
❌ Peak vs average GPU power
GPU TDP is maximum. At 1080p or in less demanding games, GPU may use 60-80% of max TDP. 4K ultra = near max.
❌ Power supply efficiency matters
An 80 PLUS Gold PSU wastes 10-15% less power than a basic PSU. Lower electricity cost over time and less heat.
