48V UPS ATX Power Supply

This KHACHIMO QUINT-PS-3X400-500AC/48DC/10 unit is a new ATX power supply delivering 48V DC output with uninterruptible capability. It integrates 80 PLUS Gold certified efficiency and Resonant LLC topology with DC-to-DC conversion for clean, consistent power delivery. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Suited for 48V backup systems

Builders assembling systems requiring a 48V DC source with battery backup support will find this unit matches their voltage and topology needs. The Zero RPM fan mode provides near-silent operation at low and medium loads, benefiting noise-sensitive environments. Systems needing a different DC output voltage or a standard ATX supply without UPS functionality should look elsewhere.

48V DC output voltage

The defining specification is the 48V DC output, which determines compatibility with the target equipment and battery configuration. This fixed voltage rail must match the input requirements of the connected hardware for correct operation. Verify that the load accepts 48V DC before purchase.
