Apple Performa 5400 Power Supply
It is not too difficult to install a new PSU in your Apple computer. The power supply in your Apple desktop supplies all the power for the hardware in the computer. Try to replace a power supply with the same wattage or larger. Purchasing a new Apple Performa 5400 PSU can be a breeze, especially if you still have the old PSU to measure, size-wise. Never go with the cheapest power supply because it is the only barrier between high amounts of electricity and your delicate computer hardware.
Key clues of a weak power supply
- You smell burnt wires in the PSU
- Your desktop will not turn on
- System shuts down while under a certain amount of stress
