KHACHIMO EX3300 900W DPST-900AL A 740-034972 power supply

KHACHIMO EX3300 900W ATX power supply

The KHACHIMO EX3300 900W unit is an ATX form factor power supply built for desktop systems that demand efficient and reliable power delivery. Its 80 PLUS Gold certification confirms high efficiency across typical loads, reducing wasted energy and operating cost. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for contemporary platforms. It suits builders assembling workstations or gaming rigs that require a 900W capacity with quiet, clean power.

Thermals, noise and power draw

80 PLUS Gold certification ensures high efficiency operation that lowers power consumption, reduces noise and keeps temperatures cooler under normal use. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine and supporting energy efficient sleep states. Together these features keep acoustic output minimal and thermal load light in typical desktop workloads.

Replaces older or lower-efficiency ATX units

This supply replaces older ATX power supplies that lack 80 PLUS Gold efficiency, Modern Standby support or semi-passive fan control. The jump is worthwhile when a system needs 900W of rated power with quieter operation and faster sleep-state transitions. Builders upgrading from units without DC-to-DC conversion gain cleaner voltage regulation and reduced coil whine. It is not for systems that require a different form factor, a lower or higher wattage rating, or non-ATX connector layouts.
