Lenovo ThinkCentre 6490 Power Supply
It is usually pretty easy to install a power supply in the ThinkCentre 6490 desktop. Never go too cheap on a PSU as it is the final barrier between the power coming from your wall and delicate components inside your Lenovo. It is always better to replace a power supply with at least the same watts, if not bigger. Purchasing a new Lenovo ThinkCentre 6490 power supply can be a breeze, especially if you still have the old PSU to measure, size-wise. The power supply in your Lenovo desktop supplies all the power for the different pieces of hardware within your desktop.
Indications of a dying main power source
- System shuts down while under a heavy load
- The PC refuses to start
- You sense burnt wires in the PSU
