SKU CH-PVCR-CZQ0Q

A 400 W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby support for fast wake and better low-load efficiency
  • 80 PLUS Gold certification for high efficiency and cooler operation
  • Zero RPM fan mode stops the fan at low and medium loads
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 400W ATX power supply in a compact 1U form factor

1U 400W Server Power Supply

This 1U form-factor unit delivers 400W of continuous power in an ATX-compatible design. It targets rack-mount servers and compact workstations that require high-density power delivery. The Gold efficiency rating helps reduce operating costs in always-on environments.

Upgrade From Lower Efficiency Units

Replacing a standard Bronze or unrated supply cuts waste heat and lowers AC draw, which matters most in multi-node racks. The Modern Standby support adds value when systems cycle through sleep states frequently. The jump pays off where density and uptime are measured daily.

Fits Dense Chassis With Clean Power Needs

The 1U height slides into shallow server cases without blocking adjacent slots. Resonant LLC topology with DC-to-DC conversion delivers stable rails for sensitive components. Zero RPM mode keeps acoustic noise down in shared rack rooms.

Questions sur cet article

What form factor does this 400W ATX power supply use for mounting?

It uses a standard ATX form factor so it fits any chassis with ATX mounting holes and a 1U height clearance.

How do you connect the DC-to-DC conversion module during installation?

The DC-to-DC conversion is built into the resonant LLC topology; you simply mount the unit and attach the standard ATX power cables — no separate module wiring is required.

When should the 80 PLUS Gold certified fan be cleaned or replaced?

Clean the fan intake when dust builds up; the Zero RPM mode means the fan stops at low load, reducing wear, so replacement is only needed if noise or vibration appears.
