900W ATX power supply for modern PCs

The KHACHIMO CAR0924FP-Z02A delivers 900 watts of continuous power through a resonant LLC topology with DC-to-DC conversion. It is built for desktop builders who need stable output and support for Modern Standby sleep states. The unit carries 80 PLUS Gold certification for high efficiency across the load range.

Sustained-load behaviour and efficiency

Under continuous demand the Gold-rated platform maintains high efficiency, reducing waste heat and keeping component stress low. DC-to-DC conversion provides tight voltage regulation on the minor rails during long sessions. Modern Standby compatibility allows the PSU to support extremely fast wake-from-sleep transitions without instability.

Thermals, noise and power draw

At low and medium loads the Zero RPM fan mode stops the cooling fan completely for near-silent operation. Resonant LLC topology reduces coil whine, contributing to quieter performance in typical use. High efficiency translates into lower power draw from the wall and cooler internal temperatures during normal operation.

Questions about this item

How much heat and fan noise does the 900W unit produce when it runs 24/7?

The 80 PLUS Gold rating keeps waste heat low, and the Zero RPM fan mode stops the fan completely at low and medium loads for silent operation.

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

A standard ATX case and motherboard with a 24-pin main connector and 8-pin CPU power socket are required.

Will the LLC resonant topology and DC-to-DC conversion cause issues with older components I keep?

The topology delivers clean, consistent power and reduces coil whine, so it works reliably with legacy parts.
