Power Supply 1stCOOL WHITE STORM 550, 550W
The 1stCOOL WHITE STORM 550 is an ATX power supply that delivers 550W continuous output with active power factor correction (APFC) and approximately 85% efficiency. Designed for standard desktop builds, it provides stable voltage rails and compatibility with modern motherboards and peripherals.
The PSU combines a 550W rated power with APFC to improve power delivery and reduce reactive power. With an ATX 24-pin motherboard connector and multiple peripheral connectors including PCIe 8-pin, SATA 15-pin, Molex and FDD, it supports a range of components and drives. The unit’s efficiency near 85% helps lower electricity consumption compared to lower-efficiency models.
Install the power supply into a compatible ATX case following the case manufacturer’s instructions. Connect the ATX 24-pin connector to the motherboard main power socket and the PCIe 8-pin connector to the graphics card if required. Attach SATA power cables to storage drives and Molex/FDD connectors to legacy peripherals as needed. Ensure all connections are secure before powering on and verify correct fan operation and stable system boot.
Use the 1stCOOL WHITE STORM 550 in systems where total component power draw does not consistently exceed 80% of the rated 550W to maintain efficiency and headroom. Ensure adequate case airflow and periodically check cable connections and dust buildup for reliable long-term operation.
