Replacement PSU for 2U FSP units

This KHACHIMO power supply is built as a direct replacement for FSP 2U 400W FSP400-602UC units. It fits compact server or workstation chassis that require the original form factor and connector layout. The unit is new and carries an ATX-type designation for standard wiring compatibility. It targets administrators refreshing aging hardware without changing cabling or mounting points.

80 PLUS Gold efficiency in a 2U envelope

The supply meets 80 PLUS Gold certification, so typical loads run with high conversion efficiency and reduced waste heat. Modern Standby support allows extremely fast wake-from-sleep transitions while maintaining low idle draw. Resonant LLC topology with DC-to-DC conversion delivers clean power rails and helps suppress coil whine. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Verify 2U clearance and connector match

Confirm the chassis can accommodate a 2U-high power supply and that the existing backplane or motherboard connectors align with the FSP400-602UC pinout. Ensure the total system draw stays within the 400 W rating under peak load. Check that the mounting screw pattern matches the original unit before ordering.

商品問答

Which wattage version of the FSP400-602UC should I pick for my build?

This model delivers 400W continuous output and is the sole capacity available for the FSP400-602UC platform.

What does the 80 PLUS Gold rating mean for daily operation?

It guarantees high efficiency across typical loads, which reduces power draw, keeps temperatures lower and allows the fan to stay off longer.

How does the ATX form factor limit where this unit can be installed?

The ATX layout fits standard desktop and 2U server chassis that accept an ATX power supply, but it will not mount in SFX or TFX cases.
