Dell D460AM-03 460W Power Supply — Replacement for XPS 8900, 8910, 8920 Desktops

Bring a Dell XPS tower back online with its correct 460W power supply.

The Dell D460AM-03 is a 460W power supply for Dell XPS 8900, 8910 and 8920 tower desktops and other Dell systems that list this part. It uses Dell connectors and mounting, provides PCIe power for graphics cards and accepts 100–240V AC input. It suits home users and repair shops restoring XPS desktops.

Restoring an XPS Tower Without Guesswork

XPS 8900-series desktops often run a dedicated graphics card, so the power supply works harder than in a basic office PC. When it fails, the system may not power on, may shut down during games or may restart under load.

The D460AM-03 matches the original 460W unit. It fits the XPS chassis, uses the same Dell connectors and provides PCIe power for the graphics card, so the system returns to its factory configuration.

Direct Fit for XPS 8900, 8910 and 8920

The supply is designed for the XPS 8900-series tower layout. Mounting holes, cable lengths and connectors match the originals, so no case changes or adapters are needed.

Steady Power Under Gaming Loads

The 460W rating supports Intel Core i5 and i7 processors with the mid-range graphics cards Dell offered in these systems, giving stable power during gaming and content creation.

Setup Instructions

How to Replace the Dell D460AM-03
