Dell Precision 220 Power Supply
Purchasing a new Dell Precision 220 PSU is quite simple as long as you have the old one for making size comparisons. It is always a good idea to replace a PSU with a similar wattage or bigger. It is a pretty straighforward job to install a power supply in your Dell computer. The PSU, or power supply, supplies all the power for the various components inside the PC. Never go too cheap on a PSU as it is the only thing between the outside power grid and your delicate internal Dell components.
Signs your primary power supply has little time left
- The PC refuses to turn on
- System shuts down while processing a taxing load
- You smell smoke in your power supply
