What is the difference between modular and non-modular power supplies?

Modular power supplies allow you to connect only the cables you need, reducing clutter and improving airflow in your PC case. Non-modular power supplies have all the cables permanently attached, which can make cable management more challenging. However, non-modular power supplies are often more affordable than modular ones.

What is the difference between 80 Plus Bronze, Silver, Gold, and Platinum certified power supplies?

80 Plus certification is a rating system that measures the efficiency of power supplies. Bronze, Silver, Gold, and Platinum are different levels of certification, with Platinum being the most efficient. A higher efficiency rating means that the power supply wastes less energy as heat, which can save you money on your electricity bill and reduce your carbon footprint.

How do I know what wattage power supply I need for my PC?

The wattage you need depends on the components in your PC, such as the CPU, GPU, and number of drives. You can use online power supply calculators to estimate your wattage needs or consult the manufacturer's recommendations for your specific components. It's generally a good idea to choose a power supply with a higher wattage than you need to allow for future upgrades and ensure stable power delivery.
