KHACHIMO 525W ATX Power Supply

This 525 watt ATX power supply delivers 80 PLUS Gold certified efficiency for lower energy consumption and cooler operation. It supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. The unit uses Resonant LLC topology with DC-to-DC conversion to provide clean, consistent power and reduce coil whine.

Compatibility and Connector Check

Verify that your system requires a standard ATX form factor power supply rated for 525 watts. Ensure the available connectors match your motherboard, graphics card, and storage devices before ordering. Confirm your case has sufficient clearance for the unit's physical dimensions.

Thermals, Noise and Power Draw

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Gold certification and the LLC resonant design reduce waste heat, keeping internal temperatures lower during normal use. This combination minimises both acoustic output and overall power draw.

Questions about this item

Does the DPSN-525AP A 341-0266-03 ship with mounting screws or power cables, or must I source them separately?

The unit is supplied as the power supply module only; mounting hardware and AC or DC cables are not included and must be obtained separately.

My chassis accepts both ATX and smaller form-factor units — why choose the ATX version of this 525 W supply?

The ATX form factor matches standard chassis mounting holes and connector placement, ensuring direct fit in full-size and mid-tower cases without adapters.

What does the 80 PLUS Gold badge mean for daily power draw and heat inside my build?

It guarantees high efficiency across typical loads, so less electricity is wasted as heat, helping keep internal temperatures lower and fan speeds reduced.
