Lenovo ThinkCentre 3349 Power Supply
The PSU, or power supply, supplies all the power for the computer. It is a pretty straighforward job to install a new PSU in your Lenovo computer. Always try to replace an old power supply with at least the same watts, if not bigger. Purchasing a new Lenovo ThinkCentre 3349 power supply is a piece of cake, provided you are still in posession of the old power supply to measure, size-wise. You do not always want to go with the cheapest PSU as it is the final barrier between the outside power grid and your delicate internal Lenovo components.
Red flags of a weakening power supply
- The Lenovo shuts down while under a certain amount of stress
- The Lenovo is unable to start
- You see smoke in your PSU of your Lenovo
