Lenovo ThinkCentre 7639 Power Supply
Never go with the cheapest power supply as it is the only thing between a large quantity of electricity and fragile internal computer components. It is a pretty straighforward job to install a power supply in the ThinkCentre 7639 desktop. Be sure to replace an old power supply with the same size or bigger. Purchasing a new Lenovo ThinkCentre 7639 power supply is easy if you have access to the old one to make a size comparison to. The PSU, or power supply, supplies all the power for the motherboard, CPU, hard drive and other components that need power.
Warnings to watch for in a bad main power source
- The PC will not turn on
- You notice smoke in your PSU of your Lenovo
- The Lenovo shuts down while processing a taxing load
