260W ATX power supply for compact systems

The KHACHIMO D19-260P1A is a 260 watt ATX power supply designed for small-form-factor desktops and workstations that demand reliable, efficient power delivery. It carries 80 PLUS Gold certification, confirming high efficiency across typical load ranges. Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load efficiency.

Sustained-load behaviour and thermal profile

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power output while reducing coil whine. The Zero RPM fan mode keeps the cooling fan stationary at low and medium loads, enabling near-silent operation during everyday tasks. When sustained demand rises, the fan engages to maintain safe temperatures without abrupt speed changes.

ATX form-factor and connector constraints

The unit follows the ATX form factor and includes a 4-pin connector among its cable set, limiting compatibility to motherboards and configurations that match this interface. Builders requiring additional PCIe power connectors or higher total wattage for discrete graphics cards must verify their component list against the available outputs before installation.

Questions about this item

How loud and hot does the 260W unit get when it runs all day?

The 80 PLUS Gold rating keeps power draw low, and the Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent, cool operation.

Which connectors does the D19-260P1A need from my existing system to work?

It uses a standard ATX 24-pin motherboard connector plus a 4-pin CPU power plug, both of which are already present on compatible PCs.

Will this supply run stably with older components I plan to keep?

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power that supports modern sleep states and works reliably with legacy hardware.
