1100W ATX Power Supply

The KHACHIMO SR860 delivers 1100 watts of continuous power for high-end desktop builds. Its 80 PLUS Gold certification ensures efficient energy conversion under typical loads. The unit targets enthusiasts and workstation users who need reliable output for demanding components.

Modern Standby and Zero RPM Fan

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. 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 provides clean power and reduces coil whine.

Replacing Lower-Capacity or Less-Efficient Units

This supply upgrades systems that require more headroom than 80 PLUS Bronze or lower-wattage designs can provide. The jump is worth it when building with power-hungry GPUs or multi-drive arrays that exceed the limits of an existing 860W or smaller unit. It is not for builders who need modular cables if this model lacks them or for cases that cannot fit a standard ATX depth.

Questions about this item

How does the 80 PLUS Gold certification affect efficiency and noise in the KHACHIMO SR860 1100W?

The 80 PLUS Gold rating means the PSU runs at high efficiency, lowering power draw, reducing heat output and allowing the fan to stay off longer for quieter operation.

What physical space and mounting does the ATX-type SR860 require?

It fits a standard ATX power-supply bay and is secured with four screws to the case rear panel.

Which cables must be connected during installation, and what common step is missed?

Attach the 24-pin motherboard and CPU power cables, plug in PCIe connectors for the graphics card, then remember to flip the rear PSU switch to "I" before powering on.
