Apple iMac MC812LL-A Power Supply
The power supply in your Apple desktop supplies all the power for the computer. You do not always want to go with the cheapest PSU as it is the final barrier between high amounts of electricity and your delicate computer hardware. Always try to replace an old power supply with the same wattage or larger. It is not too difficult to install a new PSU in the iMac MC812LL-A desktop. Purchasing a new Apple iMac MC812LL-A power supply is easy if you have access to the old one for comparison.
Key symptoms of a barely functioning main power source
- You smell burnt wires in the PSU
- The Apple refuses to turn on
- Your Apple turns off while processing a heavy load
