ATX Power Supply for Modern Standby Systems

The KHACHIMO TC SURE STAR 500W M1D-500D1 is an ATX power supply rated at 500 watts. It carries 80 PLUS Gold certification for high efficiency and lower heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The unit uses Resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power.

Standard ATX Installation with Zero RPM Fan

Installation follows the standard ATX form factor used in most desktop cases. The Zero RPM fan mode keeps the cooling fan off entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter running. Ensure the case has sufficient clearance for a standard ATX power supply and that all required power cables reach the motherboard and components.

Verify ATX Compatibility and Connector Needs

Check that your case supports a standard ATX power supply before ordering. Confirm your motherboard and graphics card power connector requirements match the cables supplied with this unit. Modern Standby features require a compatible motherboard and operating system to function. The 80 PLUS Gold rating ensures high efficiency operation for lower power consumption and cooler temperatures.
