1100W ATX Power Supply

This 1100W ATX power supply delivers high-output power for demanding desktop builds such as workstations or multi-GPU systems. It uses a resonant LLC topology with DC-to-DC conversion to provide clean, consistent power across all rails. The unit is not suited for low-power systems that do not require this capacity.

80 PLUS Gold Thermals

80 PLUS Gold certification ensures high efficiency operation for lower power consumption, less noise, and cooler temperatures. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Modern Standby & Topology

Modern Standby support allows the system to enter more energy efficient sleep states while maintaining quick resume capability. The resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation and provides stable voltage regulation. These features work together to improve overall system responsiveness and acoustic profile.

Questions about this item

How do I install the KHACHIMO 1100W ATX power supply and which step is commonly missed?

Mount the unit in a standard ATX case using the four rear screws, connect the 24-pin ATX, CPU and GPU cables to the motherboard and components, then verify the PSU power switch is set to the on position before pressing the case button.

What maintenance or replacement will this power supply need later?

The 80 PLUS Gold certified unit uses a Zero RPM fan mode that stops the fan at low and medium loads, reducing bearing wear; periodic dust removal from the intake grill with compressed air is the only routine upkeep required.

What limit appears first when the YM-2112AA01R runs under sustained load?

The 1100W maximum output rating is the primary ceiling; if total system draw approaches that figure the protection circuits will shut the unit down to prevent damage.
