Lenovo ThinkCentre 4477 Power Supply
You will not want to cut corners when buying a power supply because it is the only barrier between the outside power grid and your delicate internal Lenovo components. It is always better to replace a PSU with the same wattage or larger. Purchasing a new Lenovo ThinkCentre 4477 power supply is easy if you have access to the old one to measure, size-wise. It is a pretty straighforward job to install a new PSU in the ThinkCentre 4477 desktop. The power supply in your Lenovo desktop is in charge of distributing power to the computer.
Important signs your primary power supply has little time left
- You sense burnt wires in the power supply
- System shuts down while under a certain amount of stress
- The Lenovo will not start
