KHACHIMO 300W ATX power supply for DS-C48S-300AC DS-C9148S-K9

Compatible 300W ATX unit

This 300W ATX power supply is built for the DS-C48S-300AC and DS-C9148S-K9 platforms. It delivers the standard ATX form factor required by those specific chassis designs. Each unit is tested working before dispatch to confirm basic electrical function. It serves administrators replacing a failed original supply in compatible rack or tower systems.

Sustained delivery at rated output

The supply is rated for 300W continuous output rather than a short peak figure. Under sustained load the voltage rails remain within ATX specification limits for the duration of the session. Thermal management relies on the standard internal fan layout to exhaust heat through the rear grille. Stable operation is maintained provided the host chassis airflow meets the original system design intent.

ATX connector and power constraints

The ATX interface supplies the main 24-pin motherboard connector plus the auxiliary CPU and peripheral leads defined by the standard. Total combined draw across all rails must not exceed the 300W label rating. Systems demanding higher wattage or additional PCIe power connectors fall outside the design envelope. Builders needing greater capacity must select a different supply.
