Dell Inspiron 545S Power Supply
The PSU, or power supply, is responsible for powering the various components inside the PC. Always try to replace a power supply with a similar wattage or bigger. It is usually pretty easy to install a power supply in your Dell 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 Dell components. Purchasing a new Dell Inspiron 545S PSU can be a breeze, especially if you still have the old PSU to make a size comparison to.
Signs your PSU will have to be replaced
- Your desktop is unable to power on
- You notice burning plastic inside the PSU
- The Dell shuts down while under a heavy load
