Lenovo ThinkCentre 7220 Power Supply
Try to replace a PSU with the same size or bigger. Purchasing a new Lenovo ThinkCentre 7220 PSU is easy if you have access to the old one to make a size comparison to. It is a pretty straighforward job to install a power supply in your Lenovo computer. Never go with the cheapest power supply as it is the final barrier between the outside power grid and your delicate internal Lenovo components. The PSU, or power supply, supplies all the power for the motherboard, CPU, hard drive and other components that need power.
Major warnings your PSU is dead
- Computer will not turn on
- You sense burning plastic inside the power supply
- The Lenovo shuts down while processing a taxing load
