KHACHIMO 275W ATX Power Supply

This 275W ATX power supply delivers stable power for compact desktop builds and modern standby systems. It suits builders who need efficient, quiet operation in a standard form factor. The unit is designed for PCs that require both 54V and 12V output rails.

80 PLUS Gold Certified Efficiency

Certified 80 PLUS Gold, the supply runs at high efficiency to lower power draw, reduce heat output and keep fan noise down. This single specification confirms it meets strict efficiency targets at typical loads. The rating applies across the full operating range.

Modern Standby and Zero RPM Fan Support

Resonant LLC topology with DC-to-DC conversion enables modern standby compatibility for fast wake times and deeper sleep states. Zero RPM mode stops the fan completely at low and medium loads for silent running. The design frees up thermal headroom in space-constrained cases.

Questions about this item

What does the 275 W rating mean for a typical desktop build?

It is the maximum continuous DC power the unit can deliver across its 54 V and 12 V rails combined, so the rest of the system must draw no more than that total.

How does the ATX form factor limit installation options?

The supply follows the standard ATX footprint and rear mounting pattern, so it fits any case designed for an ATX power supply.

What physical space and connections are needed to mount the unit?

You need an ATX-compatible case bay, four rear mounting screws, and enough internal depth for the unit plus cable routing clearance.
