550W CRPS Power Supply

The KHACHIMO ENR-0955A is an ATX-form-factor unit delivering 550 watts of continuous power. It targets system builders who need a compact redundant power supply for modern standby-capable desktops or entry-level servers.

80 PLUS Gold and Zero RPM Fan

Gold-certified efficiency reduces waste heat and keeps internal temperatures lower during typical workloads. A resonant LLC topology with DC-to-DC conversion supplies clean voltage rails while suppressing coil whine. The fan remains stationary at low and medium loads for near-silent operation.

Modern Standby Compatibility

This supply supports the Modern Standby sleep state, enabling extremely fast wake times and improved low-load efficiency. Systems that do not implement Modern Standby will not benefit from this feature. Buyers needing higher wattage or non-CRPS form factors should select a different unit.

Questions sur cet article

What does the 80 PLUS Gold rating mean for efficiency on this 550W unit?

The 80 PLUS Gold certification confirms high-efficiency operation, which lowers power consumption, reduces heat output and allows the fan to run less often or stay off in Zero RPM mode.

What physical space does this ATX power supply need in the case?

It uses the standard ATX form factor, so it fits any case with an ATX PSU bay and will mount with four screws at the rear of the chassis.

How is the ENR-0955A installed and what step is often missed?

Secure the unit in the case, connect the 24-pin motherboard, CPU and GPU cables, then enable Modern Standby in the BIOS so the fast wake and low-load efficiency features actually work.
