Lenovo ThinkServer 4011 Power Supply
It is not too difficult to install a power supply in your Lenovo computer. Purchasing a new Lenovo ThinkServer 4011 power supply is easy if you have access to the old one for making size comparisons. Never go with the cheapest power supply as it is the final barrier between the outside power grid and your delicate internal Lenovo components. The PSU, or power supply, supplies all the power for the motherboard, CPU, hard drive and other components that need power. Be sure to replace an old power supply with a similar wattage or bigger.
Main clues the main power source is on its last leg
- System shuts down while under a certain amount of stress
- You notice anything burning in the PSU
- Your desktop will not start
