Dell Dimension C521 Power Supply
Never go with the cheapest power supply as it is the final barrier between the outside power grid and your delicate internal Dell components. Try to replace a power supply with the same wattage or larger. Purchasing a new Dell Dimension C521 power supply is easy if you have access to the old one to make a size comparison to. It is usually pretty easy to install a new PSU in your Dell computer. The PSU, or power supply, supplies all the power for the motherboard, CPU, hard drive and other components that need power.
Major clues of a failing main power source
- You notice burning plastic inside the PSU
- The PC will not turn on
- System shuts down while processing a certain amount of stress
