1100W Power Supply for Precision Workstations

This 1100 watt ATX power supply is built for Dell Precision T3500, T5500 and T7500 desktops. It replaces the original G821T H1100EF-00 unit in professional workstations that require high continuous power for multi-core processors and add-in cards. The unit is new and ready for immediate installation in compatible systems.

Straightforward replacement with exact fit

Installation follows the standard ATX procedure inside the Precision chassis; the connectors align with the motherboard and drive bays without adapters. The main risk is ordering this unit for a different Precision model or a non-Dell case where the mounting holes and cable lengths do not match. Verify the workstation model number before purchase to avoid a mismatch.

Questions about this item

How do I confirm the 1100W unit is working after installing it in my Precision T3500?

The system should power on normally, fans spin, and the Dell BIOS reports the PSU as G821T or H1100EF-00 with no alerts.

What comes in the box and what extra cables do I need for a T5500?

Only the 1100W PSU itself is included; the T5500 uses the same proprietary 24-pin and 8-pin connectors already on the motherboard, so no extra cables are required.
