1100W ATX power supply

The KHACHIMO NCS5501 1100W ATX power supply delivers high-efficiency power for demanding desktop systems. It carries 80 PLUS Gold certification for reduced energy waste and cooler operation. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. The unit uses Resonant LLC topology with DC-to-DC conversion for clean, consistent output.

Build integration and cable headroom

The ATX form factor fits standard chassis layouts and leaves room for cable routing behind the motherboard tray. Zero RPM fan mode stops the cooling fan entirely at low and medium loads, freeing the build from audible fan noise during idle or light work. Resonant LLC topology with DC-to-DC conversion supports modern sleep states without requiring extra configuration. Modern Standby compatibility removes the need for legacy power-state workarounds.

Capacity limits and overhead

Rated at 1100W, the supply handles multi-GPU arrangements and heavily overclocked processors with comfortable headroom. 80 PLUS Gold efficiency keeps waste heat low even when the system draws sustained high power. Zero RPM mode cannot activate once the load exceeds the medium threshold, so the fan will spin under heavy gaming or render workloads. Builds requiring more than 1100W of continuous DC power must look to a higher-capacity unit.

Questions about this item

How much continuous power can the 1100W unit deliver before protection circuits engage?

The power supply is rated for 1100W continuous output; sustained loads at or above that level will trigger over-power protection and shut the unit down.

Does the fan stay off during an all-day workload, and how much heat does the 80 PLUS Gold efficiency leave to dissipate?

Zero RPM mode stops the fan at low and medium loads, but under sustained high load the fan spins; 80 PLUS Gold efficiency typically keeps waste heat around twenty percent of output power.

Which ATX cables must already be present in the case for this PSU to connect to a standard motherboard and graphics card?

You need a 24-pin ATX motherboard connector, an 8-pin (4+4) CPU power connector, and sufficient 8-pin (6+2) PCIe connectors for your graphics card.
