Product Description
The HP 278645-002 is a 200-Watt AC power supply unit specifically manufactured for HP Presario desktop computers, particularly models within the 4400XX and 4700XX series. This power supply is responsible for converting AC power from the wall outlet into the DC voltages required by the various internal components of the computer, such as the motherboard, CPU, hard drives, and optical drives. With a 200-watt capacity, this power supply is suitable for the typical configurations of the Presario line, which were generally entry-level to mid-range consumer desktops. It provides sufficient power for standard processors, integrated graphics or low-profile discrete graphics cards, and essential peripherals. The unit supports universal AC input, allowing it to function with power sources ranging from 100V to 240V AC, making it versatile for use in different geographical locations. This power supply unit typically features an integrated cooling fan to manage thermal output and ensure stable operation. It connects to the motherboard and other components using a combination of standard ATX connectors and potentially proprietary connectors specific to the Presario chassis. The HP 274227-001 is designed as a direct replacement part to restore or maintain the functionality of the specified HP Presario models.
