PC Power Supply (PSU)
The power supply is often underestimated, but it's one of the most crucial components of your PC. It distributes electricity to all your components: CPU, graphics card, motherboard, SSD… A poorly chosen power supply can lead to crashes, unstable performance, and even burnt-out components.
Whether you're building a gaming setup or an office PC, the choice of power supply (or PSU) must be thoughtful. Aim for the right wattage, choose a quality certification, and check the necessary connectors.
What wattage should you choose for your power supply?
No need to go for 1000W if you're just playing LoL with a mid-range graphics card. Most gaming PCs perform perfectly with a 600 to 750W power supply. However, if you're targeting a high-end graphics card, liquid cooling, or an overclocked setup, it's better to allow for some overhead with a 750W to 850W power supply.
The easiest option? Use the DropReference configurator: it provides you with the exact recommended wattage based on your components in seconds.
Certifications: Bronze, Gold, Platinum… it's not just marketing
The 80 Plus certifications indicate the energy efficiency of the power supply. A 80 Plus Gold is often the best compromise: efficient, quiet, reliable, and reasonably priced. Here's a quick overview:
- 80 Plus Bronze: decent entry-level option for small budgets.
- 80 Plus Gold: excellent efficiency, good cooling, good silence.
- 80 Plus Platinum: high-end, ultra-efficient, but often expensive.
Choosing a certified power supply also means consuming less, producing less heat, and reducing the noise of your setup.
