High-output ATX power supply

The KHACHIMO PAC1K2S12-B is a 1200W ATX switching power supply built for systems that draw substantial power. It targets workstation builders and enthusiasts assembling multi-GPU rigs or heavily overclocked platforms. The unit is supplied new and has been tested working before shipment.

Tested working assurance

Each unit undergoes a functional test so it arrives ready for immediate installation. This verification step reduces the chance of a dead-on-arrival unit and eliminates the need for an initial burn-in by the builder. No additional software or accessories are bundled with the supply.

1200 watt headroom and limits

The 1200W rating provides ample headroom for dual high-end graphics cards, numerous storage devices and powerful CPU configurations. It will not suit compact cases that require SFX or TFX form factors. Builders needing redundant or server-grade hot-swap supplies should look elsewhere.

Questions about this item

Will the 1200W ATX unit need its internal fan replaced after a few years of continuous use?

The fan is the only moving part and will eventually wear out; plan to replace it if bearing noise appears after extended 24/7 operation.

What limit appears first when the supply runs at full 1200W load for long periods?

Sustained maximum output will hit the thermal protection threshold before any electrical limit, causing the unit to shut down until it cools.

How much heat and noise should I expect when this 1200W ATX supply runs all day under heavy load?

Expect noticeable fan noise and significant exhaust heat; ensure the case airflow can move that warm air out continuously.
