Lenovo ThinkCentre A51-8122 Power Supply
Purchasing a new Lenovo ThinkCentre A51-8122 power supply is easy if you have access to the old one for making size comparisons. Never go too cheap on a PSU as it is the only thing between the power coming from your wall and delicate components inside your Lenovo. The PSU, or power supply, is responsible for powering the different pieces of hardware within your desktop. It is not too difficult to install a new PSU in your Lenovo computer. Be sure to replace a power supply with at least the same watts, if not bigger.
Subtle hints the main power source is in dire straights
- Your desktop will not start
- Your Lenovo turns off while under a taxing load
- You smell anything burning in the power supply
