Replacement 240W SFF power supply

This unit is a direct replacement for HP EliteDesk 800 G1, ProDesk 400 G1 and 600 G1 small form factor desktops. It delivers 240W of continuous output power to keep the system running. The part matches HP numbers 702307-002 and 751884-001 for easy identification. Buyers receive a compatible unit that fits the original chassis.

Thermals and power draw in normal use

The 240W rating matches the factory specification for these SFF platforms. Standard internal airflow through the case cools the supply during typical office workloads. Power draw scales with the installed components and stays within the rated limit. No additional cooling measures are required for normal operation.

Build quality and connector implications

The supply uses the proprietary connector layout designed for the G1 SFF motherboard. Mounting points align with the original screw locations for a secure fit. Cable lengths are tailored to the compact chassis, reducing clutter and improving airflow. It is not suitable for standard ATX cases or motherboards that require a 24-pin connector.

Questions about this item

How do I install the 240W SFF power supply in an HP EliteDesk 800 G1 and what step is often missed?

Slide the unit into the chassis until the latch clicks, then connect the 24-pin motherboard plug and the 4-pin CPU plug; the step most people miss is locking the retention latch before tightening the rear thumbscrew.

What maintenance or replacement will the 702307-002 unit need later?

Clean the intake grill and fan blades with compressed air every 6 to 12 months; replace the whole supply if voltages drift or the fan becomes noisy.

What limit appears first when the 240W supply runs sustained loads in a ProDesk 400 600 G1 SFF?

The 240 watt output ceiling is reached before thermal limits, so the system will throttle or shut down if combined components draw more than 240W continuously.
