Precision T7400 and T7500 1100W ATX power supply

This unit is a direct-fit replacement for Dell Precision T7400 and T7500 workstations, delivering 1100W of continuous power through a standard ATX form factor. It targets system integrators and IT professionals who need a reliable, high-capacity supply for dual-processor configurations and demanding add-in cards.

80 PLUS Gold efficiency with Zero RPM fan mode

The Gold-certified design reduces waste heat and lowers operating costs, while the Zero RPM mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion supplies tight voltage regulation, minimises coil whine, and supports modern standby sleep states for faster wake times.

Suits Precision T7400

This supply matches the original H1100EF-00, N1100EF-00, G821T, NPS-1100BB A and 0R622G part numbers, so it fits the proprietary mounting and connector layout of those chassis. Builders working in standard ATX cases, or anyone requiring a different wattage or form factor, should look at other models.

Questions about this item

Does the 1100W unit have any user-replaceable parts that will need attention later?

No user-replaceable components are mentioned; the fan is internal and the unit is sealed.

What limit appears first when the PSU runs at high load for long periods?

The 80 PLUS Gold rating ensures efficiency up to the rated 1100W; sustained loads near that ceiling will hit the thermal and current limits of the design first.

How loud and hot does the supply get when it powers a workstation all day?

Zero RPM mode keeps the fan off at low and medium loads, and the LLC topology with DC-to-DC conversion reduces coil whine, so noise and heat stay minimal under typical all-day workloads.
