Lenovo H420 Power Supply
It is usually pretty easy to install a new PSU in the H420 desktop. Purchasing a new Lenovo H420 PSU is a piece of cake, provided you are still in posession of the old power supply for comparison. Always try to replace a PSU with a similar wattage or bigger. The power supply in your Lenovo desktop is responsible for powering the hard drive, motherboard and any other peripherals in the PC. Do not just look at the price of a new power supply because it is the only barrier between the power coming from your wall and delicate components inside your Lenovo.
