840W ATX Power Supply

The KHACHIMO ACE-840APU2 E209781 is an 840W ATX power supply built for industrial control computers and high-demand workstations. It delivers continuous power through a resonant LLC topology with DC-to-DC conversion for clean, stable output.

Modern Standby systems and quiet builds

This unit suits builders who need Modern Standby compatibility for rapid wake-from-sleep and 80 PLUS Gold efficiency for lower running costs. The Zero RPM fan mode keeps the system near-silent at low and medium loads. It is not for compact cases that require SFX or TFX form factors, nor for servers needing redundant hot-swap modules.

80 PLUS Gold efficiency

The single specification that decides fit is the 80 PLUS Gold certification, which guarantees high efficiency across typical loads for reduced heat and noise. Combined with the resonant LLC design, it enables deeper, more energy-efficient sleep states supported by Modern Standby hardware.

Preguntas sobre este artículo

Is the 840 W KHACHIMO ACE-840APU2 suitable for a system that needs Modern Standby support?

Yes. The unit is Modern Standby compatible, so wake-from-sleep times are extremely fast and low-load efficiency is improved.

What does the 80 PLUS Gold rating mean for daily use?

It certifies high efficiency operation, which reduces power consumption, noise and operating temperatures under typical loads.

How does the ATX form factor and 840 W output limit real-world use?

The ATX form factor fits standard cases, and the 840 W rating caps the maximum continuous power the supply can deliver to all components combined.
