By choosing this genuine replacement, you restore full stability, protect your internal components from power surges, and extend the life of your business or home office workstation.

Quick Compatibility Guide – Is This the Right Part?

Before you place your order, please verify that this power supply matches your specific system. This unit is designed for:

• HP ProDesk 400 G6 – Small Form Factor (SFF) chassis

• HP ProDesk 400 G7 – Small Form Factor (SFF) chassis

Important Form Factor Check

This 180W power supply is exclusively compatible with the Small Form Factor (SFF) version of the HP ProDesk 400 G6. The Micro Tower (MT) and Mini (DM) variants use different, lower-wattage power supplies with distinct physical dimensions and connector layouts.

To confirm your system type:

• Look at the physical size of your current desktop chassis – SFF models are compact and slim.

• Check your existing power supply label for the model number or part number.

• Refer to your HP system specifications or the sticker on the side of your PC.

Using the wrong power supply can lead to physical incompatibility or electrical damage, so please double-check before purchasing.

Why Choose a Genuine OEM HP Power Supply?

1. Perfect Fit and Connector Compatibility

Aftermarket PSUs often use universal brackets or adapter cables that may not align properly with the ProDesk 400 G6 motherboard. This genuine HP unit features the exact P1, P2, and P3 connectors in the correct pinouts, ensuring a tool-free, secure connection every time.

2. Consistent 180W Power Delivery

Rated at a steady 180 watts, this power supply provides ample and stable energy for standard office configurations, including Intel Core processors, integrated graphics, dual storage drives, and standard RAM modules. It eliminates voltage fluctuations that can corrupt data or damage sensitive components.

3. Built-in Overvoltage and Short-Circuit Protection

Genuine HP power supplies include multiple layers of electrical safeguards. These protect your motherboard, CPU, and storage drives from unexpected power spikes or short circuits – something cheaper third-party units often lack.

4. Quiet and Efficient Operation

This OEM unit is designed with a temperature-controlled fan that runs quietly under normal loads. It balances cooling and noise levels, making it ideal for open-plan offices, shared workspaces, or quiet home environments.

5. Long-Term Reliability

HP engineers these power supplies to last through thousands of power cycles. When you replace your failing unit with this genuine part, you are investing in years of dependable service, reducing future downtime and maintenance costs.

Common Symptoms That Indicate a Failing Power Supply

If you are experiencing any of the following issues with your HP ProDesk 400 G6, your power supply may need replacement:

• No power at all – The system does not respond when you press the power button, with no LED indicators or fan movement.

• Intermittent shutdowns – The PC powers off unexpectedly during moderate or heavy workloads.

• Random restarts – The system reboots without warning, often during startup or while running applications.

• Whining or clicking noises – Unusual sounds coming from the rear of the chassis, indicating a failing internal fan or capacitor.

• Peripheral malfunctions – USB devices, external drives, or keyboards disconnect and reconnect sporadically.

• Failure to wake from sleep – The system does not resume properly after entering power-saving mode.

If one or more of these symptoms match your situation, replacing the power supply is often the most cost-effective and reliable solution before other components become damaged.
