Which option is the correct expansion for PSU?

• A. Private Storage Unit
• B. Power System Unit
• C. Power Supply Unit
• D. Public Sector Utility

Answer: (C)

PSU stands for Power Supply Unit. In computer hardware, this component converts the AC power from the wall outlet into the DC voltages the motherboard, CPU, memory, and drives need to operate. It also stabilizes and regulates those voltages and provides the various connectors the system requires, like the motherboard power connector, PCIe power for graphics cards, and SATA power for drives. The other terms don’t fit because they’re not used for PC power components: Private Storage Unit isn’t a standard hardware term, Power System Unit isn’t a common label for a computer part, and Public Sector Utility refers to a government or municipal utility rather than a computer device.
