Quick Compatibility Guide – Is This the Right Part?

Before you place your order, please verify that this power supply matches your specific system. This 220W unit is designed for the following HP Slimline and Compaq Presario series desktops:

• HP Slimline s5100 series

• HP Slimline s5200 series

• HP Slimline s5300 series

• HP Slimline s5400 series

Important Form Factor Check

This 220W power supply is specifically designed for the Slimline chassis of these HP desktops. Standard tower and other chassis variants use different power supplies with distinct physical dimensions and connector layouts. The Slimline form factor is characterized by a low-profile, narrow case that stands vertically or lays horizontally.

To confirm your system type:

• Look at the physical size of your current desktop chassis – Slimline models are thin, narrow, and approximately the size of a thick book standing upright.

• 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 computer.

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 power supplies often use universal brackets or adapter cables that may not align properly with your HP Slimline motherboard. This genuine HP unit features the exact connectors in the correct pinouts, ensuring a secure connection every time. The Slimline chassis requires a specifically shaped power supply unit that fits the compact internal layout, and this OEM part is manufactured to those exact dimensions.

2. Consistent 220W Power Delivery

Rated at a steady 220 watts, this power supply provides ample and stable energy for standard Slimline configurations, including Intel or AMD processors, integrated graphics, single 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, central processing unit, and storage drives from unexpected power spikes or short circuits – something cheaper third-party units often lack. These protection features are critical for the compact Slimline chassis where components are packed closely together.

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 home entertainment centers, living rooms, quiet home offices, or shared workspaces where noise is a concern.

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. The Slimline series uses a proprietary power supply design that is not interchangeable with standard ATX units, making the OEM part the only reliable option.

Common Symptoms That Indicate a Failing Power Supply

If you are experiencing any of the following issues with your HP Slimline or CQ4000 series desktop, 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 computer powers off unexpectedly during moderate or heavy workloads, especially during media playback or multitasking.

• 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.

• Overheating issues – The system runs hot and the fan runs at maximum speed continuously, indicating the power supply is struggling to deliver consistent voltage.

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.
