🔧 Installation Guide
Quick Checklist
- Mount the PSU with its fan aligned to your case airflow.

⚠️ Special Note
Your high-power NVIDIA GeForce RTX 3060 may require multiple 8-pin PCIe power connectors. Use separate PCIe power cables from your PSU rather than daisy-chained connectors for better stability.
