48 V ATX Power Supply

The KHACHIMO AR2240 AR326 is a 350 W ATX unit built for systems that require a 48 V input. It suits compact workstations, embedded appliances or telecom-flavoured builds where a standard mains supply is not available.

80 PLUS Gold Efficiency

Certified at 80 PLUS Gold, the supply delivers high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. Resonant LLC topology with DC-to-DC conversion provides clean power rails and minimises coil whine.

Quiet-Focused Builders

Zero RPM fan mode stops the fan completely at low and medium loads, making it a fit for noise-sensitive environments. Builders needing higher wattage or a conventional AC-input ATX supply should consider other models.

Will this ATX unit fit a standard desktop case?

Yes, it follows the ATX form factor used by most mid-tower and full-tower chassis.
