280W ATX Power Supply

The KHACHIMO 280W ATX unit delivers reliable power for compact desktop builds and office workstations. It suits users who need efficient, quiet operation in small form factor systems. The supply is not intended for high-end gaming rigs or workstations that demand multiple graphics cards or heavy overclocking headroom.

Capacity and headroom

Rated at 280 watts, the unit comfortably handles mainstream CPUs, integrated graphics and a single mid-range discrete card. It runs out of headroom when powering high-wattage GPUs, large core-count processors or extensive storage arrays. The 14-pin connector layout matches specific proprietary motherboard designs, so verify compatibility before purchase.

Thermals noise and power draw

80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and lowering electricity costs. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean power delivery and minimises coil whine. Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency.

Questions about this item

Will the 14Pin connector on this 280W unit fit the motherboard header on my older FSP280-40PA build?

The supply uses a 14Pin connector labelled 530 5050; match that exact pin-out against your board's header before installing.

How can I confirm the Zero RPM Fan Mode is actually engaging after I power on the system?

Under light load the fan should stay completely still; if it spins at idle the mode is not active.

Does the HK380-16FP box include the 14Pin cable or must I source it separately?

The 14Pin cable is integrated into the unit; no separate cable purchase is required.
