FAQ

PSU Units are devices that convert electrical power from an outlet into usable power for your computer's components. They ensure your computer runs efficiently and safely. When choosing a PSU, consider wattage, efficiency ratings like 80 Plus, and the number of connectors to match your system’s needs.

PSU Units should match or exceed the total wattage required by all your computer's components. Calculate the combined power draw of your CPU, GPU, and other parts. We recommend adding a 20% buffer to ensure stability and future upgrades.

PSU Units with 80 Plus certification are more energy-efficient, reducing electricity costs and heat output. Levels range from Bronze to Titanium, with higher levels offering better efficiency. Choosing a certified unit can enhance performance and longevity while being environmentally friendly.

PSU Units: 3 things to consider before buying

When selecting PSU Units, it's crucial to consider the wattage required by your system. Calculate the total power consumption of your components, including the CPU, GPU, and other peripherals. For example, a high-performance gaming PC with a powerful graphics card might need a 750W PSU Unit or more, while a basic office setup could suffice with 450W. Remember, it's better to have a bit more wattage than you need to ensure stability and accommodate future upgrades.

Efficiency is key when choosing PSU Units because it affects both energy consumption and heat generation. Check for an 80 PLUS certification, which indicates higher efficiency levels. The ratings range from 80 PLUS Bronze to Titanium. A Gold-rated PSU Unit is often a good balance between cost and efficiency for most users. This ensures that less energy is wasted as heat, leading to lower electricity bills and a cooler operating environment.

The form factor of PSU Units should match your computer case and motherboard requirements. ATX is the most common form factor, but always double-check compatibility. Additionally, consider modular or semi-modular PSU Units if you value cable management and airflow within your case. Modular designs allow you to use only the cables you need, reducing clutter and improving airflow for better cooling performance.
