48 V 100 W ATX Power Supply

The KHACHIMO unit delivers 48 V at 2.1 A for a total of 100 W in a standard ATX form factor. It targets builders replacing or specifying a dedicated 48 V source for compatible industrial or embedded platforms. Modern Standby support allows extremely fast wake-from-sleep transitions.

80 PLUS Gold Efficiency and Silent Operation

The supply suits systems that prioritise low-load efficiency and quiet running; its Gold certification reduces waste heat and the Zero RPM fan mode stops the fan entirely at light and medium loads. Buyers needing multiple voltage rails or substantially higher total power should look elsewhere.

Resonant LLC with DC-to-DC Topology

A resonant LLC primary stage combined with DC-to-DC conversion provides clean, consistent output while reducing coil whine and enabling deeper sleep states. This topology is the key factor in deciding whether the unit matches your platform's power-quality requirements.

Questions about this item

Does the fan on this 100W ATX unit ever need replacement?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear and extending its service life.

What limits output first when this 48V 2.1A supply runs continuously?

The 100W total power rating is the ceiling; sustained loads above that will trigger protection.

How loud and hot does this Gold-rated PSU get during all-day use?

80 PLUS Gold efficiency and Zero RPM mode keep temperatures lower and noise near-silent at typical loads.
