ATX Power Supply for Modern Standby Systems

The KHACHIMO Astec X346 is an ATX switching power supply built for PCs that use Modern Standby sleep states. It delivers fast wake times and improved low-load efficiency for desktop workstations and office machines.

80 PLUS Gold Efficiency and Zero RPM Fan Mode

Certified 80 PLUS Gold, the unit runs at high efficiency to reduce power draw, heat and noise. Its Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion keeps output clean and minimises coil whine.

ATX Form Factor and Standard Connectivity Limits

As an ATX supply it fits standard chassis and uses the conventional ATX connector set, so cable reach and connector count follow the ATX specification. Builders needing proprietary server connectors or non-ATX form factors will need a different unit.

商品問答

Will the Modern Standby support work with an older motherboard that only has standard ACPI sleep states?

Modern Standby Compatible means the unit meets the low-load efficiency and fast-wake requirements; it will still power a traditional ACPI board normally, but the fast wake benefit requires a Modern Standby-capable platform.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light system load the fan should remain stationary; you can verify by watching the fan through the grille or by using monitoring software that reports fan speed at zero RPM.

Which cables are included and what must be sourced separately?

The unit is sold as the power supply only; all ATX, CPU, PCIe and peripheral cables need to be supplied from your existing build or purchased separately.
