It depends on your GPU and CPU. Entry-level builds usually function well with 500W to 600W, while high-end systems with power-hungry graphics cards typically require 850W or more to handle transient power spikes.
Fully modular power supplies allow you to plug in only the cables you need, which simplifies cable management and improves airflow inside your case. Non-modular units have all cables permanently attached.
