Lenovo ThinkCentre 9489 Power Supply
Do not just look at the price of a new power supply as it is the final barrier between the power coming from your wall and delicate components inside your Lenovo. Purchasing a new Lenovo ThinkCentre 9489 PSU is easy if you have access to the old one for comparison. The PSU, or power supply, supplies all the power for the computer. It is usually pretty easy to install a new PSU in your Lenovo computer. It is always better to replace a power supply with the same wattage or larger.
Some warnings of a faulty power supply
- You sense anything burning in the PSU
- Your desktop will not start
- Your Lenovo turns off while under a certain amount of stress
