KHACHIMO 360W ATX Power Supply

The KHACHIMO 360W ATX power supply delivers 360 watts of continuous power with 80 PLUS Gold certification. It targets office desktops and compact workstations that require efficient, reliable energy delivery. Builders seeking a straightforward replacement for standard ATX units will find it suitable. It is not intended for systems needing multiple graphics cards or very high peak loads.

Thermals Noise and Power Draw

Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. The resonant LLC topology with DC-to-DC conversion reduces coil whine and provides clean, consistent power. Modern Standby compatibility enables fast wake-from-sleep times and better low-load efficiency. These features keep temperatures lower and noise minimal during typical desktop use.

Upgrade Path and Compatibility

This unit replaces older ATX power supplies lacking Gold efficiency or semi-passive cooling. It supports Dell part numbers 3046 3040 3050 5050 5090 8940 and references TT8F5 0TT8F5 DPS-360AB-7 A D360EPM-00 for direct swap scenarios. The jump is worthwhile when moving from a Bronze or unrated unit to gain quieter operation and lower idle consumption. It does not fit proprietary small-form-factor chassis that require non-standard dimensions.

Questions about this item

How do I install this ATX power supply in a Dell OptiPlex 3040, and which step is often missed?

Mount the unit with its four screws, connect the 24-pin ATX and 4-pin CPU cables, then plug the 6-pin connector into the motherboard header — the step most people skip is that 6-pin link, which the 3040 requires for standby power.

What maintenance or replacement will this 360 W unit need over time?

The Zero RPM fan only spins above medium load, so dust builds up slowly; clean the intake grill once a year with compressed air and replace the unit if coil whine appears or efficiency drops below 80 PLUS Gold levels.

What limit appears first when this supply runs at sustained high load?

The 360 W total-output ceiling is reached before any thermal throttle; the fan stays off until medium load, then ramps up, but continuous draw above 360 W triggers over-power protection and shuts the unit down.
