KHACHIMO 250W ATX Power Supply

This KHACHIMO unit is a 250 watt ATX power supply designed for compatible Cisco WS-C2960XR-24TS network switches. It delivers the rated output required by the original equipment and carries an 80 PLUS Gold certification for high efficiency. The part number PWR-C2-250WAC matches the OEM replacement specification for these managed switches.

Sustained Load Behaviour

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery during continuous operation. 80 PLUS Gold efficiency reduces waste heat and keeps internal temperatures lower under prolonged load. The zero RPM fan mode remains inactive at higher sustained outputs, so the fan runs to manage thermal performance when the switch is fully utilised.

Installation Notes

The supply slides into the switch chassis and locks with the built-in latch mechanism. Correct alignment of the connector is essential; forcing the unit can damage the backplane pins. No additional cables or adapters are required beyond the standard AC input cord. Installers should verify the switch firmware supports hot-swap replacement before removing the old unit under power.

Questions about this item

How loud is the 250W unit when it runs all day?

The Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent operation, while 80 PLUS Gold efficiency keeps heat and coil whine low during extended use.

Which cables or connectors must I already have to install this supply?

It follows the ATX form factor, so a standard ATX motherboard power connector and the usual peripheral leads are all that are required for installation.

Will this 250W model work with older components I plan to keep?

Yes, the ATX design and DC-to-DC conversion deliver clean, consistent power that is compatible with legacy hardware you may retain.
