Frequently Asked Questions

How much wattage do I really need?

A good rule of thumb is to add the TDP (Thermal Design Power) of your CPU and GPU, add 150W for the rest of your system (motherboard, fans, SSDs), and then add a 25% "headroom" buffer. For example, if your parts total 450W, a 650W PSU is the perfect comfortable choice.

What does "80 PLUS Gold" actually mean?

It’s an efficiency rating. An 80 PLUS Gold PSU is roughly 90% efficient, meaning it wastes very little energy as heat. This results in a quieter PC (the fan doesn't need to spin as fast) and lower electricity bills over time.

Can I use a fully modular PSU in any case?

Almost always, yes. The main constraint is the Form Factor (usually ATX). Ensure your case has enough depth to accommodate the specific length of the PSU you choose, especially if you are building in a compact Mini-ITX chassis.
