HP 796416-001 400W Platinum Power Supply for Z240 Tower Workstation

Restore an HP Z240 Tower workstation with its original high-efficiency supply.

The HP 796416-001 is a 400W 80 PLUS Platinum power supply for the HP Z240 Tower Workstation and compatible HP tower desktops. It uses HP mounting and connectors and accepts 100–240V AC input. It suits engineering, design and office teams keeping Z240 workstations in service.

Why Workstations Need Efficient, Matched Power

Workstations often run all day under CAD, rendering or analysis loads. An inefficient power supply wastes energy as heat, which raises office cooling costs and internal temperatures.

The 796416-001 is rated 80 PLUS Platinum, meaning it converts most of the power it draws into usable output. As the HP-specified unit for the Z240 Tower, it also fits the chassis and connects to the HP motherboard without adapters.

Power for Professional Graphics

The 400W rating supports the Xeon E3 or Core processors and the professional graphics cards HP offered for the Z240 Tower, with headroom for drives and expansion cards.

Direct HP Replacement

Mounting points, cable lengths and HP-specific connectors match the original unit, so installation takes minutes and does not require modifications.

Setup Instructions

How to Replace the HP 796416-001

1. Shut down the Z240 Tower workstation, unplug the AC cord and press the power button for a few seconds to drain residual power.
2. Open the side panel, photograph the cable routing, then disconnect the power cables from the motherboard, drives and any graphics card.
3. Remove the mounting screws or release latch, take out the old unit and install the replacement in the same position.
4. Reconnect every cable, close the case, plug in the AC cord and power on to confirm the system boots and the fan spins.
