Direct replacement server PSU

The Lemincrash DPS-280AB-4A is a 280W single unit built for 1U server chassis that use a 6+4pin main connector. It accepts 100-240V input at 50/60Hz and carries 80 Plus series certification. The package contains only the power supply itself.

Upgrade from lower-watt 1U units

This supply replaces earlier 1U modules such as the CWT POE 7708N 7908N 7716N or KSA-300S2 when the system demands the full 280W rating. The jump is worth it when the original unit cannot sustain peak draw or when the 6+4pin interface is required for the backplane.

Steady output under continuous load

Rated for 20-90% humidity and weighing 700g, the unit is designed for sustained operation in rack environments rather than short bursts. The 80 Plus series rating indicates consistent efficiency across the load range while the single non-redundant design keeps cabling simple for compatible 1U slots.

Questions about this item

What physical space does the 280 W server PSU need to fit in a 1U chassis?

The unit is built for a standard 1U server slot and weighs 700 g; verify the exact length and height against your chassis rail spacing before mounting.

How is the 6+4-pin main connector installed, and what step is often missed?

Align the 6+4-pin plug with the motherboard socket, push until the latch clicks, then secure the unit with the chassis retention screws so vibration cannot unseat the connector.

Which components of the DPS-280AB-4A will need replacement over time?

The internal cooling fan and electrolytic capacitors are the wear items; expect to service the fan when noise rises and replace capacitors after several years of continuous 100–240 V operation.
