KHACHIMO DPS-500AB-5B 500W ATX Power Supply

This KHACHIMO DPS-500AB-5B is a 500W ATX power supply built new for compact systems. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for fast wake-from-sleep. Resonant LLC topology with DC-to-DC conversion delivers clean power and enables efficient sleep states. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Ideal for Small Form Factor Builds Needing Quiet

This unit suits builders assembling small form factor PCs who value low noise and efficient sleep behaviour. The Gold-rated efficiency and fan-stop feature benefit home theatre or office machines that idle often. Buyers who want more storage or require higher wattage for multi-GPU configurations should look at something else. Systems needing specialised server redundancy features are not the target use case.

Standard ATX Installation

Installation follows standard ATX mounting and cabling procedures familiar to most builders. The compact dimensions linked to the K39, T34 and R47 references mean cable routing space can be tight in very small chassis. Verify that your case internal layout accommodates the unit depth and connector orientation before fitting. The most common issue is insufficient clearance for stiff cables near the motherboard edge.

Questions about this item

What connectors does my motherboard need to work with the DPS-500AB-5B?

The DPS-500AB-5B uses standard ATX connectors. Your motherboard must provide a 24-pin main power socket and the appropriate CPU power connector for the unit to operate.

Can I keep using my older ATX motherboard with this 500W unit?

Yes, the DPS-500AB-5B follows the ATX specification, so it will power an older ATX board as long as the board has a 24-pin socket and matching CPU power connector.

How can I verify the Zero RPM fan mode is active after setup?

Under light load the fan should stop spinning completely. Listen for silence at idle; if the fan stays still while the system is running, the Zero RPM mode is working as intended.
