Compatible desktop power supply

The KHACHIMO 250W unit fits systems that reference part numbers such as 390, 790, 990, 3010, 7010 or 9010DT. It delivers standard ATX power in a compact form factor suitable for small-form-factor or legacy office desktops.

Gold efficiency with semi-passive cooling

An 80 PLUS Gold rating keeps power draw low and reduces waste heat during typical workloads. A Zero RPM fan mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion limits coil whine and supports modern standby sleep states.

Modern Standby ready for quick wake

The platform wakes from sleep almost instantly and maintains efficient low-power states without extra configuration. Builders should verify that the chassis and motherboard connectors match the TFX0250D5W layout before installation.

Questions about this item

How do I install this ATX power supply in my PC and which step is most often missed?

Secure the unit in the case with the standard ATX mounting screws, connect the 24-pin motherboard cable and the 4+4-pin CPU cable, then route the remaining cables; the step most often missed is the 4+4-pin CPU connector near the socket.

What maintenance will this 250 W unit need over time?

The Zero RPM fan mode keeps the fan off at low and medium loads, reducing wear; clean dust from the intake grille periodically and listen for any bearing noise that would indicate a future fan replacement.

What limit appears first when this Gold-rated supply runs under sustained load?

The 250 W rated output is the first limit; the 80 PLUS Gold efficiency and LLC resonant topology with DC-to-DC conversion help keep temperatures and coil whine low, but continuous draw above 250 W will trigger protection.
