HP 504966-001 220W Power Supply — Replacement for HP Pavilion Slimline Desktops

The right slim supply to restart an HP Pavilion Slimline desktop.

The HP 504966-001 is a 220W slim power supply for HP Pavilion Slimline desktops, including the s5000 series. It uses a narrow TFX-style housing, HP connectors and a 100–240V AC input. It suits home users and repair shops replacing a failed Slimline power supply. Available in new and refurbished condition.

Why Slimline Desktops Need a Specific Power Supply

HP Pavilion Slimline desktops use a narrow chassis that standard ATX power supplies cannot fit. When the original supply fails, the system will not start, and a generic replacement usually will not fit.

The 504966-001 is the HP part made for this chassis. It fits the slim opening, uses the original mounting and connectors, and restores the system to its factory power configuration.

Direct Fit for Slimline Models

The TFX-style housing matches the Slimline layout, so no case changes or adapters are needed. Cable lengths suit the compact interior.

Right-Sized 220W Output

A 220W rating covers the processor, memory, drives and low-profile cards used in these desktops, with integrated fan cooling to manage heat in the small case.

Setup Instructions

How to Replace the HP 504966-001

1. Shut down the Slimline desktop, 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.
