Apple MD771LL-A Power Supply
Purchasing a new Apple MD771LL-A PSU is a piece of cake, provided you are still in posession of the old power supply to measure, size-wise. Do not just look at the price of a new power supply as it is the final barrier between a large quantity of electricity and fragile internal computer components. The PSU, or power supply, supplies all the power for the hardware in the computer. It is a pretty straighforward job to install a power supply in the MD771LL-A desktop. It is always a good idea to replace a power supply with at least the same watts, if not bigger.
Simple warnings that your power supply is in need of replacing?
- Your Apple turns off while under a heavy load
- You see burning plastic inside the PSU
- The PC is unable to power on
