The power supply (SMPS/PSU) is the most overlooked part of a desktop — until it fails and takes other components with it. Here's how to spot a dying PSU and choose the right replacement.
Signs Your PSU Is Failing- PC shuts down or restarts randomly, especially under load.
- Won't power on at all — no fans, no lights (after ruling out the cable/socket).
- Burning smell, buzzing/coil whine, or a fan that has stopped spinning.
- Random freezes, or components (like a graphics card) behaving erratically.
- Add up your components' power draw (CPU + GPU are the big ones) and add ~30% headroom.
- A typical office PC needs 300–450W; a gaming PC with a dedicated GPU needs 550–850W.
- Look for an 80 PLUS rating (Bronze/Gold) for efficiency and stable voltage.
- Match the connectors your motherboard and GPU need (24-pin, CPU 8-pin, PCIe).
PSUs are sealed units with high-voltage capacitors — they are not safe to open or repair at home. When one fails, it's replaced, not repaired. A quality replacement is affordable and protects the expensive parts around it. If your PC died suddenly, a technician can confirm whether it's the PSU (a common, cheap fix) or the motherboard before you spend on parts.
