The protection features are correctly set, and contrary to the 850W model, the OCP and OPP triggering points are far under hot and cold conditions. The only exception is the 3.3V rail, where the OCP triggering point should be lower at high temperatures. The OCP and OPP triggering points under high temperatures are notably lower, effectively protecting the PSU. All the other major protection features are present and work well.
