PSU Efficiency Advice

Power supplies are most efficient at 50-60% load. Over-provisioning your PSU leads to quieter operation, lower heat, and significantly longer component lifespan.

Frequently Asked Questions

Why provision extra wattage?

System components often experience "transient spikes"—brief moments where power draw exceeds the rated TDP. A PSU with headroom prevents crashes during these peaks.

What is 80 PLUS Rating?

It's an efficiency certification. Bronze, Gold, and Platinum indicate how much power is lost as heat. Higher ratings save money on electricity and run cooler.
