Black rectangular ATX power supply unit with fan grille and cable bundle

KHACHIMO

KHACHIMO ATX3500-65PA 300W 350W power supply

SKU CH-MWHG-MW7G7

ATX power supply rated 300W with 350W peak, 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • ATX form factor rated 300 W continuous and 350 W peak power output

Compatibility & Use

This power supply is built as a direct replacement for FSP 610H 610G 610L and 810 units rated at 300 watts continuous and 350 watts peak. It fits standard ATX bays in office desktops and small-form-factor systems that require the original connector layout and power profile.

Capacity & Headroom

The unit delivers a steady 300 watts with a 350 watt peak rating, so it handles integrated graphics, mid-range discrete cards and typical multi-drive configurations. Loads that exceed the continuous rating will trip protection or cause instability, limiting its use to modest builds.

Modern Standby & Efficiency

Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency, while 80 PLUS Gold certification reduces consumption and heat. Zero RPM fan mode stops the fan at low and medium loads for silent running, and the resonant LLC topology with DC-to-DC conversion provides clean power with minimal coil whine.

Questions about this item

Will the ATX3500-65PA fit the FSP 610H chassis I already use?

The unit is built for the FSP 610H, 610G, 610L and 810 series, so it matches the mounting points and connector layout of those models.

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

At low and medium loads the cooling fan switches off entirely; you should hear no fan noise and see the blades stationary while the system is idle.

Which cables come with the ATX3500-65PA and what must I source separately?

The power supply includes the fixed ATX cables needed for the supported FSP chassis; any proprietary adapters for other cases would need to be purchased separately.
