1200W ATX power supply

The KHACHIMO CR8B0BKP03C3 is a 1200W ATX power supply built for high-performance desktops and workstations. It delivers stable power for demanding multi-GPU configurations and overclocked processors. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits builders who need reliable, high-wattage delivery in a standard form factor.

80 PLUS Gold efficiency headroom

Rated at 80 PLUS Gold, the supply maintains high efficiency across typical loads, reducing waste heat and lowering overall power consumption. The 1200W capacity provides ample headroom for multi-GPU setups and heavy compute workloads. At sustained maximum draw the unit will reach its thermal and current limits, so systems exceeding this output require a higher-rated supply. It is not for builds that need more than 1200W of continuous power.

Zero RPM fan mode and resonant LLC topology

A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power and reduces coil whine for quieter running. These features also enable more energy-efficient sleep states during idle periods. The unit is not for users who require active fan cooling at all load levels.

Questions about this item

Will the 1200W ATX unit work with my older motherboard that only has a 20+4-pin and 4-pin CPU connector?

The 80 PLUS Gold ATX supply delivers up to 1200W through standard 24-pin and 4+4-pin connectors, so it powers legacy boards without adapters.

How can I verify the Zero RPM Fan Mode is active after I build the system?

At low and medium loads the fan stops completely; you will hear near-silent operation and can confirm zero RPM in BIOS or monitoring software.

Which cables come attached to the CR8B0BKP03C3 and what must I source myself?

Fixed 24-pin motherboard, 4+4-pin CPU and PCIe leads are included; any specialised GPU adapters or extra drive cables would be separate purchases.
