Compact 120W ATX unit for small-form-factor builds

This 120-watt ATX supply targets compact NAS or HTPC chassis where space and low power draw matter. It fits 1U rackmount cases and mini-ITX boards that only need modest rail capacity. Builders chasing high-wattage GPU headroom should choose a larger unit.

Standard ATX mounting and cabling simplify install

The unit uses regular ATX screw holes and fixed cables, so it drops into any compliant 1U or mini-tower frame without adapters. Limited cable length can complicate routing in deeper enclosures, and the single 12-volt rail offers no redundancy for multi-drive arrays.

120-watt ceiling suits light NAS or office loads

At 80 PLUS Gold efficiency the supply comfortably runs a low-power CPU, a few SSDs, and a single expansion card. Sustained loads above the rated ceiling will trigger protection or shutdown, so multi-disk RAID or discrete graphics are not supported.

Perguntas sobre este artigo

How do I confirm the 80 PLUS Gold efficiency is active after installing the HEC-12SN-7FX?

The PSU meets 80 PLUS Gold certification, meaning it delivers high efficiency at typical loads; you will notice lower power draw, cooler operation and less fan noise under normal use.

What cables and accessories are included with the KHACHIMO 120W unit, and what must I source separately?

The package contains the power supply only; you will need to provide your own ATX power cables and any adapters required for your specific build.

Which version of the HEC-12SN-7FX should I choose for a small 1U NAS build?

This model is a 120W ATX supply designed for compact 1U NAS and AIO systems; its 12V output and Modern Standby support make it suited for that form factor.
