KHACHIMO PS-250FLE 250W 400W ATX power supply

SKU CH-TSZC-PC306

ATX power supply rated 250 W continuous and 400 W peak with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant DC-to-DC topology for silent, efficient operation

  • Product typeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold certification cuts energy use and heat
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC topology with DC-to-DC delivers clean, stable power
  • Rated 250 W continuous with 400 W peak capacity

Compact 250W ATX power supply

The KHACHIMO PS-250FLE delivers a rated 250 W and a peak of 400 W from a standard ATX footprint, making it suitable for compact NAS units, 1U enclosures or low-power workstations. Its 80 PLUS Gold certification ensures high efficiency, reducing heat and lowering electricity draw under typical loads.

Fits tight chassis and enables silent low-load

A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion provides clean power and reduces coil whine. Modern Standby compatibility allows extremely fast wake-from-sleep transitions, freeing the system from long resume delays in always-on or sleep-heavy deployments.

Replaces noisy or inefficient low-wattage units

Builders upgrading from older bronze-rated or fixed-speed fan supplies gain measurable efficiency and acoustic improvements without changing form factor. The jump is worthwhile when the existing unit cannot meet 80 PLUS Gold efficiency, lacks a semi-passive mode or does not support Modern Standby sleep states.

Questions about this item

What is the peak power limit the PS-250FLE can reach before protection triggers?

The unit is rated for 250 W continuous output and can deliver up to 400 W peak power for short bursts before its protection circuits engage.

How does the Zero RPM fan mode affect noise and heat during all-day operation?

At low and medium loads the fan stops completely for silent running; 80 PLUS Gold efficiency keeps waste heat low so temperatures stay controlled even under sustained use.

What motherboard power connector must the system already have for this ATX supply to work?

The PS-250FLE uses a standard ATX 24-pin main connector plus a 4-pin or 8-pin CPU power connector, so the motherboard must provide matching sockets.
