Choosing a power supply, answered.
How much wattage do I need?
Add up the draw of your CPU and graphics card, then leave headroom for upgrades — a quality unit with some spare capacity runs cooler and quieter.
What does 80 PLUS mean?
The 80 PLUS rating measures efficiency; higher tiers like Bronze, Gold and Platinum waste less power as heat and can lower running costs.
Should I choose a modular PSU?
Modular and semi-modular units let you connect only the cables you need, improving airflow and making cable management tidier.
