1158W ATX Power Supply

The KHACHIMO 1158W ATX unit delivers high-output power for demanding desktop builds. It targets enthusiasts assembling workstations or high-end gaming rigs that require substantial continuous wattage. The 80 PLUS Gold certification confirms efficient energy conversion across typical load ranges. Modern Standby compatibility ensures rapid wake-from-sleep responsiveness for supported platforms.

Resonant LLC with DC-to-DC topology

Resonant LLC topology paired with DC-to-DC conversion supplies clean, consistent voltage to sensitive components. This architecture reduces coil whine and supports deeper, more energy-efficient sleep states. The design frees thermal headroom by minimising waste heat during operation. Builders gain a stable foundation for multi-GPU configurations and power-hungry processors.

Zero RPM fan mode under load

Zero RPM fan mode keeps the cooling fan stationary at low and medium loads for near-silent running. Under sustained heavy demand the fan engages to maintain safe temperatures without abrupt speed spikes. 80 PLUS Gold efficiency lowers overall heat output during prolonged sessions. The supply suits users who prioritise acoustic comfort alongside continuous high-wattage delivery.

Questions about this item

Will the 1158W output stay stable during long gaming sessions?

The 80 PLUS Gold certification means high efficiency is maintained across typical loads, so the unit delivers its rated 1158W with minimal waste heat.

How loud is the fan when the PC runs all day?

Zero RPM Fan Mode stops the fan completely at low and medium loads, and the LLC resonant topology reduces coil whine for quieter operation.

Which motherboard power connectors must my board already have?

This is a standard ATX power supply, so your motherboard needs the usual 24-pin ATX and 4-pin or 8-pin CPU power connectors.
