Lenovo BladeCenter HS21 Power Supply
It is always better to replace an old power supply with a similar wattage or bigger. The PSU, or power supply, is in charge of distributing power to the various components inside the PC. Purchasing a new Lenovo BladeCenter HS21 PSU is quite simple as long as you have the old one to make a size comparison to. You do not always want to go with the cheapest PSU because it is an important barrier between high amounts of electricity and your delicate computer hardware. It is not too difficult to install a new PSU in your Lenovo computer.
Cues to watch for in a bad main power source
- The Lenovo shuts down while under a taxing load
- You smell burnt wires in the power supply
- Your desktop will not turn on
