KHACHIMO 10Pin 650W ATX PSU

The KHACHIMO 10Pin 650W ATX power supply is built for desktop systems that require an 80 PLUS Gold efficiency rating and Modern Standby compatibility. Its 10-pin main connector targets specific OEM platforms such as the FSP650-50AGPAA series, making it a direct-fit replacement for compatible chassis.

Capacity and headroom at 650W

The 650W rating delivers reliable power for mid-range graphics cards and multi-core processors under typical gaming or productivity loads. Headroom diminishes when paired with high-end GPUs drawing 300W or more alongside heavily overclocked CPUs, where peak transient spikes can exceed the unit’s sustained capability.

Build quality and daily implications

Resonant LLC topology with DC-to-DC conversion supplies clean voltage regulation and reduces coil whine, while the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. The fixed cable bundle includes the proprietary 10-pin connector, so builders must verify pin-out compatibility with their motherboard before installation.

Questions about this item

Will the 10-pin connector fit the motherboard used in my FSP300 or FSP400 system?

The unit is listed as compatible with P300 P310 P320 P330 P340 P350 chassis codes, so the 10-pin connector matches those proprietary motherboards.

How can I confirm the Zero RPM fan mode is active after installation?

At low and medium loads the cooling fan switches off entirely; you will hear near-silent operation until the load rises enough to spin the fan.

Does the box include the 10-pin cable or must I source it separately?

The 10-pin cable is integrated into the power supply, so no separate cable purchase is required for the listed P300-P350 systems.
