Frequently Asked Questions

Modular PSUs allow you to connect only the cables you need, improving airflow and reducing clutter. Semi-modular units offer a middle ground, while non-modular units are typically more affordable but can make cable management more difficult.
80 Plus ratings (White, Bronze, Gold, Platinum, Titanium) indicate how efficiently a power supply converts AC power to DC. Higher ratings mean less energy wasted as heat, leading to lower electricity bills and cooler operation inside your case.
Calculate the total power draw of your CPU, GPU, and other components. It is advisable to choose a PSU with 20-30% headroom above your estimated maximum load to ensure stability and allow for future upgrades without replacing the unit.
