Lenovo ThinkCentre 7774 Power Supply
It is always better to replace a PSU with the same size or bigger. It is usually pretty easy to install a power supply in the ThinkCentre 7774 desktop. The PSU, or power supply, is in charge of distributing power to the hard drive, motherboard and any other peripherals in the PC. Purchasing a new Lenovo ThinkCentre 7774 power supply is a piece of cake, provided you are still in posession of the old power supply to make a size comparison to. You will not want to cut corners when buying a power supply as it is the only thing between the power coming from your wall and delicate components inside your Lenovo.
Subtle hints your primary power supply will eventually need to be replaced
- You smell anything burning in the power supply
- System shuts down while under a heavy load
- The PC refuses to turn on
