HP 240 W SFF Power Supply

This HP 240 W SFF power supply is built for small-form-factor HP DC7xxx desktops. It delivers 240 W through a compact switching design that fits the proprietary chassis. The unit is intended as a direct replacement for the original DPS-240MB-1-A module. It is not suited for standard ATX cases or systems that require higher wattage.

Thermals and noise

The switching topology runs efficiently at typical office loads, keeping heat output modest inside the tight SFF enclosure. Fan noise stays low during everyday productivity tasks because the 240 W capacity is rarely fully taxed. Power draw scales with the connected components, so idle consumption remains minimal. The supply is not designed for sustained heavy loads such as discrete graphics cards.

Highlights

Questions about this item

How do I install this 240 W SFF power supply into an HP DC7xxx chassis?

Slide the unit into the small-form-factor bay until the latch clicks, then connect the main ATX and CPU power cables to the motherboard; the step most often missed is seating the latch fully so the supply locks in place.

Which components of this 240 W SFF power supply typically need replacement after extended use?

The internal cooling fan and electrolytic capacitors are the parts that wear out first; when the fan becomes noisy or voltages drift, replace the whole unit rather than individual components.
