Is there "coil whine" (a high-pitched buzzing) or loud fan noise?
[Gold/Platinum] efficiency rating is noticeable in heat output; fully modular design helps airflow; Zero RPM fan mode actually works. power supply wattage

| Condition | Outcome | |-----------|---------| | | System shuts down under load; OCP (over-current protection) triggers; potential data corruption. | | Barely adequate (e.g., 550W for 520W load) | PSU runs near 100% constantly, leading to high heat, fan noise, reduced lifespan, and low efficiency. | | Over-wattage (e.g., 1200W for 400W load) | Not harmful to components, but the PSU operates in a low-efficiency zone (<20% load) if 80 PLUS certified; wastes a few percent extra electricity. | | Optimum (e.g., 750W for 400W load) | PSU runs at ~53% load → peak efficiency region → cooler, quieter, longer life. | | | Barely adequate (e
