Power Supplies (PSUs) – The Heart of Your PC in South Africa

🔌 What is a Power Supply (PSU)?

A Power Supply Unit is the part of a computer that converts electricity from your wall socket into a safe, usable form for your PC components.
It’s basically the heart of your computer—if it’s weak or unstable, your whole system suffers.

⚡ Why Your PSU Matters

• A good PSU keeps your PC running smoothly and protects it from power surges.
• A cheap or faulty PSU can cause crashes, overheating, or even damage expensive parts like your graphics card or motherboard.
• In South Africa, where load shedding and power fluctuations are common, a reliable PSU with surge protection is extra important.

🖥️ Types of PSUs

1. Standard (Non-Modular) – All cables are permanently attached. Cheaper but harder to manage cables.
2. Semi-Modular – Essential cables are fixed, extras can be added when needed.
3. Fully Modular – All cables can be connected or removed; best for cable management.

📏 How to Choose the Right PSU

• Wattage: Gaming PCs may need 650W–850W, while basic PCs can work on 400W–500W.
• Efficiency Rating: Look for 80 PLUS Bronze, Silver, Gold, or Platinum for better power savings.
• Brand Quality: Stick to well-known, reliable brands to avoid failures.
• Protection Features: Surge, over-voltage, and short-circuit protection are must-haves in South Africa.

I don’t share product links or videos because product models and availability in South Africa change often, and there’s a risk of scams.
