  • 80 PLUS Gold certification delivers high efficiency for lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation

  • 250W ATX form factor fits compact 1U systems requiring reliable switching power

Compact 250W ATX power supply for 1U systems

The KHACHIMO FSP250-60WS1 is a 250W ATX power supply designed for 1U chassis and other space-constrained builds. It delivers reliable power for entry-level workstations, thin clients or embedded appliances where physical space is at a premium.

80 PLUS Gold efficiency with 250W continuous output

Rated at 250W, the unit holds 80 PLUS Gold certification for high efficiency across typical loads, reducing waste heat and electricity draw. The resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight, though the fixed 250W ceiling limits use with discrete graphics cards or high-core-count CPUs.

Modern Standby support and zero-RPM fan profile

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. The zero-RPM fan mode stops the fan entirely at low and medium loads for near-silent operation, while the 1U form factor frees up vertical clearance in compact enclosures.

Questions about this item

Will the KHACHIMO FSP250-60WS1 fit and power an older ATX chassis I already own?

Yes, it follows the ATX form factor and delivers 250W, matching the standard mounting points and power connector layout used by older cases and motherboards.

How can I verify the 80 PLUS Gold efficiency and Modern Standby support are active after installation?

Enter the BIOS or OS power settings to confirm Modern Standby (S0ix) is enabled, and monitor input power at idle; the Gold rating means the unit should draw very little wall power at low loads.

What cables come attached to the FSP250-60WS1 and must I buy any separately?

The power supply has a fixed cable harness; check the connector ends against your motherboard and drive requirements before purchase, as no modular cables are included or sold separately.
