KHACHIMO TURBO-COOL 510 550W ATX Power Supply

This KHACHIMO TURBO-COOL 510 unit delivers 550W of continuous power through a standard ATX form factor. It is built for desktop PCs and industrial control equipment requiring reliable, efficient energy conversion. The 80 PLUS Gold certification confirms high efficiency across typical load ranges. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for compatible systems.

Sustained load behaviour with Zero RPM Fan Mode

Under sustained load the Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. The Zero RPM fan mode keeps the cooling fan off entirely at low and medium loads for near-silent operation. At higher sustained loads the fan engages to maintain thermal performance without sacrificing efficiency. This design supports more energy efficient sleep states during prolonged use periods.

Straightforward ATX installation

Installation follows standard ATX mounting patterns using four case screws and a single motherboard power connector. The fixed cable set requires routing space behind the motherboard tray for tidy cable management. Builders should verify case depth clearance for the power supply length before fitting. The unit suits new system builds rather than upgrades needing modular cables or higher wattage headroom.

Questions about this item

How loud does the 550W unit get when it runs 24/7?

The Zero RPM fan mode stops the fan completely at low and medium loads, so the power supply runs silently during typical all-day use.

Which cables must my build already provide for this 510 model to power on?

It uses the standard ATX 24-pin main connector and an 8-pin EPS connector for the CPU; both must be present on your motherboard.

Will this 550W supply work with my older motherboard that lacks Modern Standby support?

Yes, the Modern Standby compatibility is an extra feature; the unit functions normally with any ATX motherboard that has the required power connectors.
