Questions & Answers
What is a power supply unit (PSU)?
A PSU converts AC mains power to regulated DC voltages, distributes stable current to all PC components, and protects against voltage spikes.
How do I determine the right PSU wattage for my computer?
Sum the maximum power draw of CPU, GPU, drives, and peripherals, then add 20–30% headroom to select a reliable PSU wattage.
What does 80 PLUS certification mean?
An 80 PLUS rating guarantees at least 80% conversion efficiency at 20%, 50% and 100% loads, reducing energy waste and heat output.
What is the difference between modular, semi-modular, and non-modular PSUs?
Modular PSUs detach all cables, semi-modular has fixed essential cables, and non-modular has permanently attached cables, affecting build flexibility and cable management.
