ℹ️ Important Usage Notes
Zero RPM Mode: The fan operates at zero RPM until the PSU reaches 40% load or ambient temperature reaches 60°C, ensuring silent operation during light tasks.
12VHPWR Cable Usage: Ensure all components do not exceed the PSU’s 850W capacity. Do not bend the cable near the connector. All connectors should be inserted tightly.
SFX Form Factor: The SP850 is designed for SFX-compatible cases. An ATX-to-SFX bracket is not included — please ensure your case supports SFX power supplies or purchase an adapter separately if needed.
