Lenovo ThinkServer RD640 Power Supply
It is a pretty straighforward job to install a new PSU in the ThinkServer RD640 desktop. The power supply in your Lenovo desktop supplies all the power for the different pieces of hardware within your desktop. Never go too cheap on a PSU because it is an important barrier between the outside power grid and your delicate internal Lenovo components. It is always a good idea to replace a PSU with a similar wattage or bigger. Purchasing a new Lenovo ThinkServer RD640 PSU is easy if you have access to the old one to measure, size-wise.
What signals that my power supply has gone bad?
- System shuts down while under a heavy load
- You notice anything burning in the power supply
- The Lenovo is unable to power on
