Monitor system stability and temperatures during initial use to verify proper cooling and load handling.

Recommendations

Use the PSU within its rated 850 W output and avoid continuous overload. Maintain adequate airflow in the case, keep dust away from the 120 mm fan, and use the provided cable lengths to minimize tension on connectors. For systems approaching the upper power limits, verify combined component power draw to ensure sufficient headroom.
