Purpose-built 1U Flex ATX power supply

The NShi ENP-7660B is a 600W unit designed specifically for the K39 server chassis. It targets builders assembling compact 1U systems who need a high-output power source that fits the Flex ATX form factor. The 110-264V input range suits global mains voltages without manual switching.

Full modular cabling with 20+4 pin and 12V outputs

A fully modular design lets you attach only the cables required, reducing clutter inside the tight 1U enclosure. The included 20+4 pin motherboard connector and dedicated 12V output cover the primary power rails for modern platforms. Metal construction and a low-noise cooling fan keep operation quiet while maintaining airflow in dense layouts.

600W continuous output with multi-rail protections

The single deciding specification is the 600W rated delivery backed by overcurrent, overvoltage and short-circuit safeguards. This capacity ceiling determines whether the unit can sustain your chosen CPU and GPU combination under load. Builders planning multi-GPU arrays or extreme overclocks should verify their total draw against this 600W limit before committing.
