Lenovo ThinkCentre 3142 Power Supply
It is always better to replace an old power supply with the same wattage or larger. The power supply in your Lenovo desktop is responsible for powering the hard drive, motherboard and any other peripherals in the PC. Purchasing a new Lenovo ThinkCentre 3142 power supply can be a breeze, especially if you still have the old PSU to measure, size-wise. Never go too cheap on a PSU because it is the only barrier between a large quantity of electricity and fragile internal computer components. It is usually pretty easy to install a new PSU in your Lenovo computer.
What to see if the PSU is in need of replacing?
- System shuts down while under a taxing load
- Computer will not start
- You notice smoke in your power supply
