KHACHIMO C7000 2450W ATX power supply

2450W ATX power supply for high-density servers

The KHACHIMO C7000 delivers 2450W of continuous power in a standard ATX form factor, making it suitable for multi-GPU workstations and dense compute nodes that demand sustained output. Its 80 PLUS Gold certification ensures high efficiency across the load range, reducing waste heat and operating cost. Modern Standby compatibility enables extremely fast wake-from-sleep transitions for always-on workloads. Builders needing more than 2450W or redundant hot-swap modules should look elsewhere.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC primary stage combined with DC-to-DC secondary regulation provides clean, consistent power and reduces coil whine for quieter operation. This topology also enables the use of more energy-efficient sleep states, complementing the Modern Standby feature. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running when the system is idle. Systems requiring fully passive cooling under load or active power factor correction above the rated specification are not addressed by this design.

80 PLUS Gold headroom and thermal behaviour

At typical server loads the unit operates well within its Gold efficiency band, keeping temperatures lower and fan speeds minimal. The fan remains off up to moderate loads, so acoustic output stays near zero during background tasks. Under sustained maximum draw the fan engages to maintain safe thermals, and headroom above 2450W is not available. Deployments that must sustain peaks beyond the rated wattage or that rely on external fan control curves not supported by the unit will exceed its capacity.
