KHACHIMO 3040 5040 7040 180W ATX supply

This new ATX power supply delivers up to 180 W for compact or low-power desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower heat output. The unit supports Modern Standby for rapid wake-from-sleep and features an 8-pin connector layout compatible with specific Dell chassis.

Suits small-form-factor upgrades needing Gold

Ideal for users replacing a failed OEM unit in compatible 3040, 5040 or 7040 systems who want quieter operation. The Zero RPM fan mode stops the fan at low and medium loads. Builders requiring higher wattage for discrete graphics cards or multiple drives should look at higher-capacity alternatives.

Resonant LLC topology with DC-to-DC conversion

This design supplies clean, consistent power while reducing coil whine and enabling efficient sleep states. Combined with Gold-rated efficiency, it keeps temperatures and noise down in space-constrained cases. The 180 W rating is the key figure to match against your system's total power draw.

Questions about this item

Will the 180W ATX unit power my older Dell OptiPlex 3040, 5040 or 7040 that uses the 8-pin connector?

Yes, the 180W ATX supply is listed for the 3040, 5040 and 7040 models and includes the required 8-pin connector for those systems.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

The fan stays off at low and medium loads, so silent operation at idle is the immediate sign; 80 PLUS Gold certification means the unit meets the programme's efficiency targets under test conditions.

Does the box include the 8-pin cable or must I source it separately?

The 8-pin connector is built into the power supply, so no separate cable purchase is needed for the supported 3040, 5040 or 7040 chassis.
