HP 404472-001 240W ATX12V supply

This 240 W ATX12V power supply is built for HP Compaq DC5700 and DC5750 microtower desktops. It replaces the original unit in office PCs that need a direct-fit replacement. The internal form factor matches the chassis mounting points and connector layout exactly. It is not suited for builds requiring higher wattage or standard ATX dimensions outside those models.

Dual +12 V rails at 7 A and 11.5 A

The unit provides two +12 V rails rated at 7 A and 11.50 A alongside 3.3 V at 15 A and 5 V at 17 A. This split-rail design determines whether the supply can deliver enough 12 V current for the installed components. Buyers needing a single high-current 12 V rail for modern graphics cards should look elsewhere.

110 V or 220 V AC input with WEEE certification

The power supply accepts 110 V AC and 220 V AC input and meets WEEE and China RoHS environmental standards. At 3.06 lb it fits the microtower cavity without extra clearance concerns. Normal office loads run within the 240 W rating, keeping fan noise low and thermals stable.

Perguntas sobre este artigo

What does the 240 W rating mean once this supply is installed in a real machine?

The 240 W rating is the total continuous power the unit can deliver across all rails, with 3.3 V at 15 A, 5 V at 17 A, two 12 V rails at 7 A and 11.5 A, -12 V at 150 mA and 5 V standby at 2 A.

What interface does this power supply use and what does it limit in practice?

It uses the ATX12V standard with a 20/24-pin main connector and a 4-pin 12 V CPU connector, limiting compatibility to motherboards that accept those connectors.

What does this unit physically need to fit and mount in a case?

It is an internal ATX form-factor unit weighing 3.06 lb, designed to mount in HP Compaq DC5700 and DC5750 microtower chassis with standard ATX screw holes.
