Hello @vizaykr

Welcome to the TechForum

Based on the information you have provided, you may want to look at Murata Power Solutions series D1U54-D-1500 (1500W), as well as Bel Power Solutions PFE1500 (1500W) and TFS1500-12-054xD (1500W) series. But just like David_1528 said we would need more specific information to be able to help you further.

A 1500W DC-input ATX power supply is a fairly specialized product. Before recommending a solution, it would help to know:

  • Input voltage range (12V, 24V, 48V, or something else?)

  • Required ATX outputs (+12V, +5V, +3.3V, etc.)

  • Whether this is for telecom, automotive, battery, or solar operation

  • Continuous load vs. peak load requirements

At 1500W, the input current can become quite significant. For example, with a 12V input, the supply would need to handle well over 100A, which makes the design much more challenging than a standard AC-input server PSU.

There are commercial DC-DC server power supplies available for 24V and 48V systems, and in some cases it may be easier to use a telecom-grade DC power system rather than designing a custom 1500W ATX supply.
