🔌 Power Budget
Your system uses 70% of the recommended PSU output — well within the efficient operating range.
550W (Recommended)
System draw: 385W
Headroom: 165W (30%)
💡 Why 550W?
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
Upgrade to 750W+ Gold PSU for safety and transient spikes.
Use separate PCIe cables for the GPU instead of daisy-chaining.
🎯 What This Build Can Do
Gaming
Suitable for modern games with good performance based on your system configuration.
Productivity

🔧 Installation Guide
Quick Checklist
- Mount the PSU with its fan aligned to your case airflow.
- Only connect cables you actually need (modular PSUs).
