SKU CH-5DAA-9A28H

New 550 W ATX unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and LLC resonant topology for quiet, stable power

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified for high efficiency and lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine
  • 550W ATX power supply designed for SFF systems with a 6-pin connector

Product Identity

The KHACHIMO 510S-07ICB is a 550 W ATX power supply designed for small form factor systems such as the 280 G2 and 400 G4. It carries 80 PLUS Gold certification and includes Modern Standby support for rapid wake times and improved low-load efficiency. A zero RPM fan mode stops the fan completely at low and medium loads for near-silent running.

Suitability

This unit fits builders upgrading an SFF workstation that uses a 6-pin power connector and needs higher capacity than the original 180 W designs. It is not for buyers whose chassis lacks room for a standard ATX PSU or whose motherboard requires a different connector layout.

Deciding Specification

The 550 W rated output combined with 80 PLUS Gold efficiency is the figure that determines whether this supply can handle your components. Resonant LLC topology with DC-to-DC conversion delivers clean power and enables deeper sleep states for compatible platforms.

Questions about this item

What is the first limit reached under sustained load with the 550W rating?

The 550W power limit is the first ceiling; sustained draw above that triggers protection or shutdown.

How does the Zero RPM Fan Mode affect noise and heat during all-day operation?

The fan stays off at low and medium loads for silent running, then spins up only when higher temperatures demand active cooling.

Which power connectors must the existing system provide for this unit to work?

A 6-pin connector is required; the unit is designed for SFF chassis such as the 510S-07ICB, M420, 280G2 and 400G4 models.
