KHACHIMO Power Supply PSR3000-54A 3000W 80 PLUS Gold

SKU CH-61MZ-2DJ7C

A 3000W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for silent, low-load operation

  • TypeATX
  • Modern Standby support enables near-instant wake from sleep
  • 80 PLUS Gold certification delivers high efficiency for lower power draw
  • Zero RPM fan mode stops the fan completely at low and medium loads
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power
  • ATX form factor fits standard desktop chassis

Modern Standby Power Supply

This ATX power supply delivers 3000W of 80 PLUS Gold certified power and is built for Modern Standby compatibility. The Resonant LLC topology with DC-to-DC conversion provides clean, consistent output while enabling efficient sleep states. A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Suitable For Systems Needing High Efficiency

It suits builders who want high efficiency, low noise, and fast wake-from-sleep capability in a Modern Standby environment. Buyers who need a lower-wattage unit for a compact build or a tighter budget should look at something else. Systems that cannot accommodate a 3000W ATX form factor will require a different power supply.

3000W 80 PLUS Gold Rating

The 3000W 80 PLUS Gold rating is the single specification that decides whether this unit matches the power and efficiency demands of the build. Verify that the system’s peak draw fits within this capacity and that the efficiency target aligns with the project goals. This figure determines if the PSU is the right part for the configuration.

Questions about this item

How do I install the PSR3000-54A and which cable routing step is often missed?

Mount the ATX unit in the case with four screws, connect the 24-pin motherboard, CPU and GPU cables, then verify the 54 A rail is not overloaded by a single high-draw card.

What maintenance will the PSR3000-54A need after extended use?

Clean dust from the intake grill periodically; the Zero RPM fan mode means the fan spins only above medium load, so bearings see less wear and rarely require replacement.

What limit appears first when the PSR3000-54A runs at sustained high load?

The 3000 W maximum output is the hard ceiling; once total draw reaches that figure the protection circuit shuts the unit down to prevent damage.
