💡 Why 1000W?
Power Calculation
CPU + GPU draw, plus ~100W for motherboard, RAM, fans, and storage.
30% Headroom
Extra capacity absorbs transient power spikes, keeps efficiency in the sweet spot, and leaves room for future upgrades.
80 Plus Efficiency
We only recommend certified PSUs. Higher ratings mean less wasted energy, lower heat, and quieter fans.
🌿 Power Efficiency Tips
Use native 12V-2×6 cable for GPU efficiency.
Ensure high-airflow case for the 350W TDP CPU.
🎯 What This Build Can Do
Gaming
