Dell OptiPlex SX280 Power Supply
Purchasing a new Dell OptiPlex SX280 PSU is a piece of cake, provided you are still in posession of the old power supply to make a size comparison to. Never go with the cheapest power supply as it is the only thing between a large quantity of electricity and fragile internal computer components. It is usually pretty easy to install a new PSU in your Dell computer. The PSU, or power supply, is in charge of distributing power to the different pieces of hardware within your desktop. It is always a good idea to replace a PSU with at least the same watts, if not bigger.
Signs of a dying power supply
- You sense smoke in your PSU of your Dell
