Intel ATX12V manual Over-temperature Protection, Output Bypass

ATX12V Power Supply Design Guide

Version 2.0

3.4.5. Over-temperature Protection

The power supply may include an over-temperature protection sensor, which can trip and shut down the power supply at a preset temperature point. Such an overheated condition is typically the result of internal current overloading or a cooling fan failure. If the protection circuit is nonlatching, then it should have hysteresis built in to avoid intermittent tripping.

3.4.6. Output Bypass

The output return may be connected to the power supply chassis. The return will be connected to the system chassis by the system components.
