Server PSU for Industrial PCs

The TOPOWER TOP-400W2U-PFC is a 400W single ATX12V and EPS12V power supply built for industrial PCs and server chassis. It delivers +12V at 26A and +5VSB at 3A through a 20+4 pin main connector with sliding contacts. The unit accepts 100 to 240 V input and fits standard 2U form factors.

Installation notes and common issues

Two 40 mm fans provide thermally controlled cooling with silent control technology. The sliding main connectors accommodate both 20/24 pin and 4/8 pin motherboard headers without adapters. Verify that the chassis airflow path matches the dual-fan exhaust layout to avoid recirculation. Ensure the gray iron case mounting holes align with your rack rails before securing.

Pre-order compatibility checks

Confirm the chassis depth accepts the 7.87 x 3.94 x 2.76 inch dimensions and that the 20+4 pin main connector matches your motherboard power socket. Check that the +3.3V and +5V rails at 24A each meet your board requirements. The unit includes OVP, OCP and SCP protection on all outputs. Builders needing redundant hot-swap capability should consider other models.

Въпроси за този артикул

How can I confirm the TOPOWER TOP-400W2U-PFC is operating correctly after installation?

Verify the system powers on stably and the 2x40mm fans spin up with thermally controlled speed; the gray iron case should stay cool and no protection lights trigger under load.

What connectors come with the 400W unit and what must I source separately?

The unit provides 20/24-pin and 4/8-pin main sliding connectors; any extra cables for drives or expansion cards are not included and must be obtained separately.

Which version of the TOP-400W2U-PFC should I select for a standard 2U server build?

Choose the single 400W option with ATX12V/EPS12V design, 100-240V input, and 7.87" x 3.94" x 2.76" dimensions to fit a typical 2U chassis.
