KHACHIMO CRPS 820W ATX Power Supply

The KHACHIMO CRPS 820W is an ATX switching power supply built for modern desktop PCs. It delivers 820 watts of continuous power with 80 PLUS Gold certified efficiency. The unit supports Modern Standby for rapid wake times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides stable voltage regulation and reduced electrical noise.

Suited for builders wanting efficient.

This supply fits builders who value high efficiency and near-silent operation at low loads thanks to a Zero RPM fan mode. It is not for systems that require power above 820 watts. It is not for compact chassis that demand SFX or TFX form factors. It is not for servers needing redundant CRPS hot-swap modules.

820W ATX with 80 PLUS Gold certification

The single specification that decides fit is the 820 watt ATX rating combined with 80 PLUS Gold efficiency. This determines whether the unit can handle the system's peak power draw while meeting the efficiency target. Verify the total system power requirement against this 820 watt limit before purchasing.

Questions about this item

Is the 820 W version the right choice for my build or should I look for a different capacity?

The unit delivers 820 W of continuous power, making it suitable for systems with mid-range to high-end graphics cards and multi-core CPUs that stay within that total draw.

What does the 80 PLUS Gold rating mean once the supply is installed in my PC?

It certifies high efficiency across typical loads, so less electricity is wasted as heat, helping to keep temperatures and fan noise lower.

What interface does this power supply use and what does that limit in practice?

It uses the standard ATX form factor, so it fits regular ATX cases and connects to motherboards and components with the usual 24-pin, EPS and PCIe cables.
