  • Designed for SR6604/08/16 series routers with 650W ATX power output

650W ATX power supply

The KHACHIMO SR6604/08/16 series unit delivers 650 watts of continuous power in a standard ATX form factor. It targets builders assembling workstations or gaming systems that require reliable, efficient energy conversion without excess capacity. The design supports modern standby sleep states for rapid wake times.

Sustained-load behaviour

Under continuous demand the resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and low ripple across the 80 PLUS Gold efficiency curve. The zero-RPM fan mode keeps the cooler inactive through low and medium loads, eliminating acoustic noise while temperatures remain controlled. At higher sustained output the fan engages to preserve thermal headroom.

ATX interface limits

The ATX connector set defines the maximum number of peripherals and graphics cards that can be powered simultaneously. Builders needing more PCIe power connectors or higher total wattage than 650 watts must select a larger unit. The fixed cable layout also restricts routing options in compact chassis.

Perguntas sobre este artigo

How loud and hot does the 650W unit get when it runs continuously?

The 80 PLUS Gold rating keeps efficiency high, reducing waste heat, while Zero RPM mode stops the fan at low and medium loads for near-silent operation.

What must my system already have for this ATX power supply to work?

A standard ATX motherboard with 24-pin and CPU power connectors, plus a case that fits an ATX PSU.

Will the SR6604 series PSU power my older components reliably?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine, supporting modern sleep states on legacy hardware.
