500W ATX power module for S2300

This new KHACHIMO 500W ATX power supply carries part numbers PSC500-A, YM-2501BAR and WOPSA5000 and is built specifically for the S2300 platform. It delivers 500 watts of continuous power with 80 PLUS Gold certified efficiency, Modern Standby support for fast wake times and a Zero RPM fan mode that stops the fan at low and medium loads.

Ideal for S2300 owners wanting Gold efficiency

Builders upgrading or repairing an S2300 system will benefit from the resonant LLC topology with DC-to-DC conversion, which reduces coil whine and enables deeper sleep states. This unit is not for anyone needing a different form factor, higher wattage or a model qualified for another chassis.

The deciding specification is the S2300-qualified

Only the WOPSA5000 / PSC500-A / YM-2501BAR combination is validated for the S2300; using a different 500W ATX supply risks incompatibility with the platform's power delivery and sleep-state requirements.

Questions about this item

What maintenance will the 500W PSU fan need over time?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing bearing wear and dust build-up, so the fan requires less frequent cleaning or replacement.

What limit appears first when the 500W PSU runs at full load continuously?

The 500W rated output is the ceiling; sustained draws above this trigger over-power protection and shut the unit down.

How much heat and noise does the 500W PSU produce during all-day operation?

80 PLUS Gold efficiency keeps waste heat low, and the Zero RPM Fan Mode keeps the unit silent until loads exceed the medium threshold.
