KHACHIMO

KHACHIMO 48V 12.5A 600W ATX Power Supply 80 PLUS Gold

SKU CH-4352-5Q2A1

ATX unit delivers 600 W at 48 V and 12.5 A with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for quiet, clean power

  • TypeATX
  • 80 PLUS Gold certification cuts power draw and keeps temperatures lower
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Modern Standby support gives extremely fast wake-from-sleep and better low-load efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • 600 W output at 48 V / 12.5 A provides strong capacity for demanding builds

Purpose-built ATX unit

This ATX power supply delivers a fixed 48 V output at 12.5 A for a total of 600 W, making it a direct replacement for the TDK-Lambda RWS600B-48 in compatible systems. It is intended for builders or technicians who need that exact voltage and current rating rather than a standard multi-rail desktop unit.

Efficiency and acoustics

The 80 PLUS Gold certification means the unit runs at high efficiency across typical loads, reducing waste heat and fan demand. A Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion keeps output clean and suppresses coil whine, together enabling quieter operation and deeper sleep states.

Installation notes

The supply uses a standard ATX form factor, so it fits the usual mounting points and connector layout for that chassis style. Modern Standby compatibility ensures fast wake-from-sleep behaviour without extra configuration. Buyers who need adjustable voltages, multiple 12 V rails or higher total wattage should look elsewhere.

Perguntas sobre este artigo

Will the fan need replacement after long-term use?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing mechanical wear and extending the fan's operational life.

What limits sustained output at full 600W load?

The 80 PLUS Gold certified unit delivers up to 600W continuously; sustained operation at that level is limited by the 48V 12.5A rated output capacity.

How loud and hot does it get when running all day?

Zero RPM Fan Mode keeps it near-silent at low and medium loads, while 80 PLUS Gold efficiency reduces waste heat for cooler temperatures during extended use.
