Lenovo S40-40 Power Supply
The power supply in your Lenovo desktop supplies all the power for the different components that make up your Lenovo desktop. It is a pretty straighforward job to install a power supply in the S40-40 desktop. Never go too cheap on a PSU as it is the only thing between a large quantity of electricity and fragile internal computer components. It is always better to replace a PSU with the same size or bigger. Purchasing a new Lenovo S40-40 power supply is quite simple as long as you have the old one for comparison.
Key indicators that my PSU is almost dead?
- You smell smoke in your PSU
- Computer is unable to start
- The Lenovo shuts down while under a taxing load
