  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low loads for silent running
  • LLC resonant plus DC-to-DC gives clean, stable power
  • Single 12 V rail delivers 2000 W for heavy loads

Industrial 12 V 2000 W ATX power supply

The KHACHIMO 851 delivers a single 12 V rail rated at 2000 W in a 2U ATX form factor. It is built for industrial control systems and high-density mining rigs that demand continuous, high-current 12 V output.

Sustained-load behaviour and efficiency

80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and fan noise during extended operation. Resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and low ripple when the supply runs at full rated power for long periods.

Installation notes and common pitfalls

The 2U height fits standard rackmount chassis but will not suit conventional tower cases designed for shorter PSUs. A single 12 V rail means every peripheral connector draws from the same rail; installers must ensure the total connected load never exceeds the 2000 W rating.

Questions sur cet article

How loud and hot does the 2000W unit get when running continuously?

The 80 Plus Gold certification keeps efficiency high, reducing waste heat and fan noise, while Zero RPM mode stops the fan entirely at low and medium loads for near-silent operation.

What cables or connectors must I already have to install this ATX power supply?

It uses the standard ATX form factor, so your case must accept an ATX PSU and your motherboard needs the usual 24-pin and CPU power connectors.

Will the 12V single-rail design work reliably with older components I plan to keep?

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power across the 12V rail, supporting modern sleep states and stable operation with legacy parts.
