Staying Powered. Choosing a Reliable PSU

 **7. Staying Powered: Choosing a Reliable PSU**

The Power Supply Unit (PSU) is the unsung hero of any computer. It ensures all components receive stable and sufficient power, enabling the system to run smoothly. Choosing a reliable PSU is essential for performance and hardware longevity.

What to consider:
- **Wattage:** Calculate your system's power requirements, factoring in the CPU, GPU, and other components. Using online PSU calculators can help. Always aim for a bit of extra wattage to allow for future upgrades.
- **Efficiency:** Look for PSUs with 80 Plus certifications, such as Bronze, Gold, or Platinum. Higher efficiency ratings reduce energy consumption and heat production.
- **Build Quality:** Trusted brands with protective features like overcurrent, overvoltage, and short-circuit protection offer peace of mind.

A high-quality PSU not only powers your PC but also protects your investment by preventing power-related damage to expensive components.
