KHACHIMO R33640G1 1500W ATX Power Supply

1500W ATX power supply for high-load systems

The KHACHIMO R33640G1 delivers 1500W of continuous power through an ATX form factor, suited to workstations and multi-GPU rigs that draw heavy current. Its 80 PLUS Gold certification means high efficiency at typical loads, reducing waste heat and keeping operating temperatures lower. Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load efficiency for systems that use deep sleep states.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC design combined with DC-to-DC conversion supplies clean, consistent voltage rails while cutting coil whine for quieter running. At low and medium loads the Zero RPM fan mode stops the cooling fan entirely, giving near-silent operation during idle or light workloads. These features together lower acoustic output and support more energy-efficient sleep states without extra configuration.

Verify ATX clearance and cable reach before ordering

Confirm the case can accommodate a standard ATX power supply and that the fixed cable lengths reach every component, especially in larger enclosures. Ensure the motherboard and graphics cards use connectors this unit provides, as no modular cable kit is mentioned. Builders needing higher wattage, redundant supplies or server-grade form factors should look elsewhere.
