KHACHIMO 700W ATX Power Supply

The KHACHIMO YM-2681H delivers up to 700 watts of continuous power for desktop systems. It targets builders who need reliable ATX energy delivery with modern sleep-state support. The unit suits mainstream gaming rigs and workstations that demand efficient, quiet operation. It is not for servers requiring redundant supplies or extreme overclocking headroom beyond the rated output.

680W Continuous with Gold Efficiency

Rated at 680 watts continuous and peaking at 700 watts, the supply handles mid-range graphics cards and multi-core processors comfortably. 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and fan noise. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation under shifting demands. It runs out of headroom when total system draw approaches the 700 watt limit.

Modern Standby and Zero RPM Cooling

Modern Standby compatibility enables near-instant wake from sleep while drawing minimal idle power. Zero RPM fan mode stops the fan entirely at low and medium loads for silent desktop use. Standard ATX dimensions and cabling fit typical chassis without modification. The design frees builders from configuring fan curves for quiet low-load operation.

Questions about this item

Will the 680W/700W ATX unit fit and power an older motherboard with a 24-pin connector?

The supply uses the standard ATX form factor and 24-pin main connector, so it fits older boards that follow the same ATX specification.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM mode are active after installation?

At low and medium loads the fan stops completely, and the 80 PLUS Gold rating means the unit meets the published efficiency targets under typical loads.

Which cables come in the box and what extra cables might I need for a legacy GPU?

The box includes the ATX power supply unit; any additional PCIe or peripheral cables required for older graphics cards must be purchased separately.
