Lenovo ThinkCentre A57E Power Supply
Purchasing a new Lenovo ThinkCentre A57E PSU is quite simple as long as you have the old one for making size comparisons. It is always a good idea to replace an old power supply with a similar wattage or bigger. The PSU, or power supply, supplies all the power for the motherboard, CPU, hard drive and other components that need power. Never go with the cheapest power supply as it is the only thing between high amounts of electricity and your delicate computer hardware. It is usually pretty easy to install a power supply in your Lenovo computer.
Signals of a deteriorating primary power supply
