Quizplus · Accepted Answer

- The floppy drive needs a single, specific power connector.
- The PATA optical drive needs a single, specific power connector.
- Each SATA hard drive needs a single, specific power connector.
- The external SATA hard drive likely comes with its own power adapter and does not require a power connection from the power supply.
- The external USB hard drive does not require a power connection from the power supply.

Therefore, we need 1+1+2=3 unique power connection types from the power supply for all the storage devices in the computer.
