KHACHIMO X3755M3 1100W ATX Power Supply

This new ATX power supply delivers 1100W of continuous power for desktop workstations and high-performance gaming PCs. It holds an 80 PLUS Gold certification for high efficiency across typical load ranges. The unit uses Resonant LLC topology with DC-to-DC conversion to provide clean, consistent output voltage regulation. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency.

Ideal for Modern Standby systems needing silent

Builders who want near-silent idle performance benefit from the Zero RPM fan mode that stops the fan entirely at low and medium loads. The resonant LLC design reduces coil whine for quieter operation during demanding workloads. Systems that cannot use Modern Standby sleep states or do not require 80 PLUS Gold efficiency levels will not utilise the key features of this unit. Buyers needing a different form factor or lower maximum output should look at other models.

1100W ATX with 80 PLUS Gold and Modern Standby

The single specification that decides fit is the 1100W ATX rating combined with Modern Standby compatibility and 80 PLUS Gold efficiency. This defines the power ceiling, form factor, sleep-state support and efficiency class in one fixed combination. If the build requires a different wattage, a non-ATX form factor, or lacks Modern Standby support, this power supply will not match the system requirements.

Questions about this item

What ATX case clearance does the X3755M3 1100W unit need?

It follows the standard ATX form factor, so any case that accepts an ATX power supply will fit.

Which cables must be connected during installation to enable Modern Standby?

Connect the 24-pin ATX, 8-pin EPS, and any required PCIe cables; the PS-2112-2M then handles Modern Standby signalling automatically.

When should the cooling fan be cleaned to keep Zero RPM mode effective?

Remove dust from the fan intake whenever it becomes visible; the Zero RPM feature will then continue to stop the fan at low and medium loads.
