Lenovo ThinkStation 4157 Power Supply
It is always a good idea to replace a power supply with a similar wattage or bigger. Purchasing a new Lenovo ThinkStation 4157 PSU is a piece of cake, provided you are still in posession of the old power supply for making size comparisons. Do not just look at the price of a new power supply because it is an important barrier between high amounts of electricity and your delicate computer hardware. The PSU, or power supply, is in charge of distributing power to the various components inside the PC. It is usually pretty easy to install a power supply in your Lenovo computer.
Major symptoms of an inadequate power supply
- You smell burnt wires in the PSU of your Lenovo
- System shuts down while under a taxing load
- Your desktop refuses to turn on
