Lenovo ThinkCentre 9439 Power Supply
Always try to replace a PSU with a similar wattage or bigger. The PSU, or power supply, is responsible for powering the different components that make up your Lenovo desktop. It is usually pretty easy to install a power supply in the ThinkCentre 9439 desktop. Do not just look at the price of a new power supply as it is the only thing between a large quantity of electricity and fragile internal computer components. Purchasing a new Lenovo ThinkCentre 9439 PSU is a piece of cake, provided you are still in posession of the old power supply to measure, size-wise.
How can I tell if my power supply is dying?
- The PC is unable to start
- The Lenovo shuts down while under a certain amount of stress
- You notice smoke in your PSU
