2U 460W ATX Power Supply

The KHACHIMO SS-460H2U is a 2U form-factor ATX power supply rated at 460W, designed for rackmount chassis and compact server builds where vertical space is limited. It targets system integrators and IT professionals deploying dense, always-on infrastructure.

Sustained-load behaviour

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power across the full operating range while suppressing coil whine. 80 PLUS Gold certification ensures high efficiency under continuous load, reducing waste heat and keeping internal temperatures lower during prolonged operation.

Modern Standby compatibility

Modern Standby support enables extremely fast wake-from-sleep transitions and improved low-load efficiency, making this unit the right choice for deployments that rely on connected standby states rather than traditional S3 sleep.

Questions about this item

How loud and hot does the KHACHIMO SS-460H2U get during all-day use?

Its 80 PLUS Gold efficiency keeps waste heat low, and the Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running.

What cables or connectors must my build already have for this ATX power supply to work?

The unit follows the ATX form factor, so it connects to a standard 24-pin motherboard socket and a 4/8-pin CPU power header.

Will the Resonant LLC and DC-to-DC topology work reliably with older components I keep in the system?

Yes, that topology delivers clean, consistent power and reduces coil whine, which helps stability with legacy parts.
