550W ATX Power Supply

The KHACHIMO unit delivers 550W of continuous power in a standard ATX form factor. It targets desktop builders who need reliable energy for mid-range components and Modern Standby sleep states.

80 PLUS Gold efficiency headroom

Gold certification means the supply runs at high efficiency across typical loads, reducing waste heat and fan noise. The 550W ceiling covers mainstream CPUs and single GPUs, while multi-GPU or extreme overclocking setups would exceed its capacity.

Resonant LLC topology with Zero RPM fan

A resonant LLC design paired with DC-to-DC conversion supplies clean voltage and reduces coil whine. The Zero RPM mode stops the fan completely at low and medium loads, and Modern Standby compatibility enables near-instant wake from sleep.

Perguntas sobre este artigo

Will this 550W ATX unit work with an older motherboard that still uses a 20-pin main connector?

The supply follows the ATX form factor, so it provides the standard 20+4-pin connector that fits both 20-pin and 24-pin motherboard sockets.

How can I confirm the 80 PLUS Gold efficiency is active once the PSU is installed?

At typical loads the fan will remain off thanks to Zero RPM mode, and the system should wake from sleep almost instantly, showing the Gold-rated platform is operating.

Does the box include the 6-pin PCIe cable shown in the model name, or must I buy it separately?

The 6-pin PCIe connector is native to this 550W unit, so the required cable is supplied in the box; no separate purchase is needed.
