Targeted server power replacement

The Lemincrash KSA-180S2 is a 180W server power supply built for systems that require the DPS-200PB-203A or DPS-200PB-185A form factor. It accepts a wide 100-240V input at 47-63Hz, making it suitable for global deployment in compatible rack or tower chassis. The unit delivers a combined 12V and 52V output configuration for specific server backplane requirements. Buyers needing a different voltage mix or higher wattage should verify their chassis specification before ordering.

Compact 80 Plus build with single-unit packaging

Weighing 700g, the supply uses a switching topology certified to the 80 Plus efficiency standard, reducing waste heat inside dense server enclosures. The package contains only the PSU itself, so installers must reuse existing mounting screws, cables, and any chassis-specific brackets. No additional connectors or adapters are included, meaning the existing wiring harness must match the unit’s native pinout exactly. Technicians should confirm physical clearance and connector keying against the confirmation picture prior to installation.

Direct swap for DPS-200PB series units

This model replaces the DPS-200PB-203A and DPS-200PB-185A power modules when the part number and photo match the original hardware. The upgrade is worthwhile when the existing supply has failed, shows voltage drift, or cannot sustain load under continuous 180W operation. It is not a capacity increase over the original 180W rating, so systems already at the power budget limit will not gain headroom. Compatibility hinges on an exact part-number match; servers using other Delta or OEM form factors cannot use this unit.

Questions about this item

What does the 80 Plus rating mean for the 180W output?

The 80 Plus label confirms the supply meets certified efficiency levels across typical loads, so more of the 180W drawn from the wall reaches the 12V and 52V rails as usable power.

What physical space and mounting does the KSA-180S2 require?

The unit weighs 700g and uses the standard server PSU form factor, so it fits the same chassis bays and screw pattern as the DPS-200PB-203A and DPS-200PB-185A it replaces.

What is the installation step people often miss?

Verify the part number on the label matches KSA-180S2 exactly and confirm the 100-240V, 47-63Hz input range suits your mains supply before sliding the unit into the bay and latching it.
