SKU CH-3T7C-G3M6K

A 500 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low load for silent running
  • LLC resonant topology with DC-to-DC delivers clean power
  • Replaces V2H-5350V and V2H-5400V units

500W ATX power supply for servers

The KHACHIMO 2U unit delivers 500W of continuous power in a standard ATX form factor. It targets rack-mount servers and workstations that require reliable, efficient power delivery within a 2U chassis height. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency for always-on environments.

Replaces V2H-5350V and V2H-5400V units

This model supersedes the earlier V2H-5350V and V2H-5400V power supplies, offering 80 PLUS Gold certified efficiency and a resonant LLC topology with DC-to-DC conversion. The upgrade is worth it when you need cleaner power output, reduced coil whine, and support for deeper, more energy-efficient sleep states in compatible systems.

Standard ATX mounting simplifies installation

Installation follows conventional ATX mounting patterns, fitting directly into 2U server chassis designed for this form factor. The Zero RPM fan mode activates automatically at low and medium loads, eliminating fan noise without user configuration. Ensure the 2U height restriction matches your chassis before purchase, as taller units will not fit.

Questions sur cet article

What rack height does the 2U 500W ATX power supply require?

The unit is built to the 2U form factor, so it fits in any standard 2U rack space or chassis bay.

How do you connect the P2H-5500V or P2H-5550V to the motherboard, and what step is often missed?

Attach the 24-pin ATX connector and the CPU power cable; the step often missed is fully seating the 24-pin latch until it clicks.

When will the fan on this 80 PLUS Gold unit need cleaning or replacement?

The Zero RPM mode keeps the fan off at low and medium loads, so dust builds slowly; clean the intake when airflow feels reduced, and replace the fan only if it becomes noisy or stops spinning.
