Compact 600W ATX supply for small-form-factor builds

The KHACHIMO ENP-7660B delivers 600 watts in an ATX form factor suited to space-constrained chassis such as 1U or flexible NAS enclosures. It targets builders who need reliable power in a tight footprint without sacrificing efficiency certifications.

80 PLUS Gold efficiency rating

Independent 80 PLUS Gold certification guarantees high efficiency across typical loads, reducing waste heat and lowering overall power draw. This single metric confirms the unit meets strict efficiency thresholds for continuous operation.

Zero RPM fan mode and resonant LLC topology

At low and medium loads the cooling fan stops completely for silent running while the resonant LLC design with DC-to-DC conversion maintains clean voltage regulation. Under sustained load the topology keeps ripple low and coil whine minimal even during extended sessions.

Questions about this item

What does the 600W rating mean for my build?

The 600W rating is the maximum continuous power the unit can deliver to all components combined; your total system draw should stay below this figure.

How does the 80 PLUS Gold certification affect daily use?

80 PLUS Gold certifies high efficiency at typical loads, so the PSU wastes less electricity as heat and runs cooler and quieter.

Will the 1U form factor fit in a standard ATX case?

The ENP-7660B is a 1U flexible-ATX design intended for slim NAS or server chassis; it will not mount in a regular ATX tower without an adapter bracket.
