KHACHIMO R510 R910 750W ATX Power Supply

The KHACHIMO R510 R910 CPS750-D121 is a new 750W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency, lower power draw and reduced heat. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine.

Who This Suits and Who Should Look Elsewhere

This unit suits builders who want a Gold-efficient ATX supply with a Zero RPM fan mode that stops the fan entirely at low and medium loads for near-silent operation. It also fits systems that rely on Modern Standby sleep states for quick resume. Buyers who need a higher wattage than 750W, a different form factor such as SFX, or a non-modular cable design not described here should look at other options.

The Deciding Specification: 750W 80 PLUS Gold ATX

The single specification that decides fit is the 750W 80 PLUS Gold ATX rating. It defines the maximum continuous power available to components and the efficiency level you will get at typical loads. If your build requires more than 750W or a different efficiency tier, this is not the right part. Confirm your total system draw and case compatibility before buying.
