Lenovo ThinkStation 6439 Power Supply
The power supply in your Lenovo desktop is responsible for powering the motherboard, CPU, hard drive and other components that need power. Try to replace a PSU with a similar wattage or bigger. It is usually pretty easy to install a new PSU in your Lenovo computer. You do not always want to go with the cheapest PSU because it is the only barrier between the outside power grid and your delicate internal Lenovo components. Purchasing a new Lenovo ThinkStation 6439 power supply is quite simple as long as you have the old one to measure, size-wise.
Some warnings the main power source is not going to last much longer
- Computer refuses to start
- System shuts down while under a taxing load
- You see smoke in your PSU of your Lenovo
