Lenovo ThinkServer 391 Power Supply
Purchasing a new Lenovo ThinkServer 391 power supply is quite simple as long as you have the old one to measure, size-wise. The PSU, or power supply, is responsible for powering the different components that make up your Lenovo desktop. It is always a good idea to replace a PSU with the same wattage or larger. It is a pretty straighforward job to install a new PSU in the ThinkServer 391 desktop. Never go with the cheapest power supply because it is the only barrier between high amounts of electricity and your delicate computer hardware.
What symptoms are present when the PSU is in need of replacing?
- System shuts down while processing a taxing load
- The PC will not start
- You see burning plastic inside the PSU
