Dell Precision 390 Power Supply
It is a pretty straighforward job to install a new PSU in the Precision 390 desktop. You do not always want to go with the cheapest PSU because it is an important barrier between a large quantity of electricity and fragile internal computer components. It is always better to replace a PSU with at least the same watts, if not bigger. Purchasing a new Dell Precision 390 PSU can be a breeze, especially if you still have the old PSU for making size comparisons. The PSU, or power supply, supplies all the power for the various components inside the PC.
Major signs the main power source is failing
- The Dell is unable to start
- The Dell shuts down while processing a certain amount of stress
- You see smoke in your PSU of your Dell
