🔌 Power Budget
Your system uses 71% of the recommended PSU output — well within the efficient operating range.
850W (Recommended)
System draw: 600W
Headroom: 250W (30%)
💡 Why 850W?
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 1000W+ if adding a high-end GPU in the future.
Enable Eco Mode to reduce CPU heat during non-critical workloads.
🎯 What This Build Can Do
Software Development
Compiling massive codebases and running complex simulations with high core counts.
Video Production
High-resolution 8K video editing and CPU-based rendering for professional studio workflows.
Virtualization Lab
Hosting dozens of virtual machines or containers for server testing and development.
🔧 Installation Guide
Quick Checklist
- Mount the PSU with its fan aligned to your case airflow.
- Only connect cables you actually need (modular PSUs).
- Use dedicated PCIe power cables for NVIDIA GeForce RTX 5060 — no daisy-chaining.
- Boot-test with side panel open before final assembly.
⚠️ Special Note
Check if motherboard requires two 8-pin EPS cables for the Threadripper CPU.
