  • 80 PLUS Gold certified for high efficiency and lower power consumption

KHACHIMO 240W ATX Power Supply

The KHACHIMO 240W unit is an ATX form-factor power supply built for desktop PCs that require a compact, efficient power source. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine.

Suits small-form-factor and office builds

This supply suits builders assembling low-power small-form-factor systems or office workstations where quiet operation and efficient sleep states matter. The Zero RPM fan mode keeps noise near zero at low and medium loads. Builders needing more than 240W for discrete graphics cards, high-core-count CPUs, or multiple drives should look at higher-capacity units instead.

240W continuous capacity with Gold efficiency

The 240W rating provides comfortable headroom for integrated graphics configurations, entry-level CPUs, and a modest complement of storage and peripherals. At typical office workloads the unit runs in its highest-efficiency band, keeping temperatures low and the fan off. Sustained loads that approach the 240W limit will engage active cooling and leave little margin for future upgrades.

Questions about this item

Does my motherboard need a 24-pin ATX connector and an 8-pin EPS connector for this 240W ATX power supply?

Yes, this ATX unit provides a 24-pin motherboard connector and an 8-pin EPS connector for CPU power.

Will the 80 PLUS Gold efficiency and Modern Standby support work correctly with my older Haswell or Skylake system?

The supply meets 80 PLUS Gold efficiency at all loads and supports Modern Standby sleep states, which function on any ATX motherboard that implements the required low-power C-states.

How can I confirm the Zero RPM fan mode is active after I build the PC?

Under light desktop loads the fan will stop spinning completely; you can verify this visually through the case vent or by monitoring fan-speed RPM reading zero in the BIOS or software utilities.
