460W ATX Power Supply

The KHACHIMO PS-2461-7H is a 460W ATX power supply designed for servers and workstations using compatible RH1288V3, RH2288V3, 2285 or 1288V2 chassis. It suits administrators who need reliable, efficient power delivery for 24/7 operation in supported rackmount or tower systems.

Build Integration

This unit fits directly into the listed server models without adapter brackets or cable modifications. Its 80 PLUS Gold certification reduces waste heat, easing the burden on chassis airflow and allowing quieter fan curves elsewhere in the build. The ATX form factor ensures standard mounting screw alignment for the supported platforms.

Sustained Load Behaviour

Resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation during continuous workloads, minimising ripple and coil whine. Zero RPM fan mode keeps the unit silent at low and medium loads, while Modern Standby compatibility enables rapid wake transitions without destabilising the power rails.

Highlights

  • Lower power draw and cooler running from 80 PLUS Gold efficiency
  • Near-silent operation at low load with Zero RPM fan mode
  • Clean, stable power delivery via resonant LLC and DC-to-DC topology
  • Reduced coil whine for quieter overall system acoustics

Questions about this item

What limits sustained output on this 460W PS-2461-7H unit?

The unit is rated for 460 W continuous output; exceeding that limit triggers its protection circuits and shuts the supply down.

How loud and hot does the PS-2461-7H get during all-day operation?

Its Zero RPM mode stops the fan completely at low and medium loads, while 80 PLUS Gold efficiency keeps waste heat and noise low even under sustained use.

Which cables or connectors must I already have for this PS-2461-7H to work?

It uses standard ATX connectors, so a motherboard with a 24-pin main power socket and matching CPU/PCIe leads is all that is required.
