How many pins does a SATA power cable have?

  1. 4

  2. 8

  3. 15

  4. 20

The correct answer is: 15

SATA power cables typically have 15 pins, as they are used to connect peripherals like hard drives and solid state drives to a motherboard. Option A, 4 pins, is not an adequate number of pins for this type of connection. Option B, 8 pins, is a common number of pins for a CPU power cable, but not for a SATA power cable. Option D, 20 pins, is a common number for a connection like ATX, but again not for a SATA power cable. Remember, SATA power cables have 15 pins for their specific purpose in the computer hardware setup.
