Lenovo 3000 9689 Power Supply
Always try to replace a PSU with at least the same watts, if not bigger. Purchasing a new Lenovo 3000 9689 power supply can be a breeze, especially if you still have the old PSU for comparison. The PSU, or power supply, is responsible for powering the motherboard, CPU, hard drive and other components that need power. You do not always want to go with the cheapest PSU because it is the only barrier between high amounts of electricity and your delicate computer hardware. It is usually pretty easy to install a power supply in your Lenovo computer.
Signs the power supply is in need of replacing
- You sense anything burning in the power supply
- Your desktop refuses to power on
- Your Lenovo turns off while under a certain amount of stress
