Dell OptiPlex GX400 Power Supply
Purchasing a new Dell OptiPlex GX400 PSU is a piece of cake, provided you are still in posession of the old power supply to make a size comparison to. It is not too difficult to install a new PSU in your Dell computer. Never go too cheap on a PSU because it is an important barrier between the power coming from your wall and delicate components inside your Dell. Try to replace a PSU with the same wattage or larger. The power supply in your Dell desktop is responsible for powering the motherboard, CPU, hard drive and other components that need power.
Major symptoms to watch for in a failing power supply
- You sense burnt wires in the power supply
- Your desktop will not turn on
- The Dell shuts down while under a heavy load
