Protection Features Evaluation

The OCP triggering points are set as expected on all the rails. OPP is set notably lower than on the AX1600i, which triggered at 1907.21 W.

DC Power Sequencing

According to Intel's most recent Power Supply Design Guide (revision 1.4), the +12 V and +5 V rails must have voltages equal to or greater than the +3.3 V rail's output at all times. For our first measurement, we turn the unit off and switch it back on without a load on any of the rails.



There is a problem here since the 3.3 V rail starts to increase its voltage before the 5 V rail.

EMC Pre-Compliance Testing - Average and Quasi-Peak EMI Detector Results

Electromagnetic Compatibility (EMC) is the ability of a device to operate properly in its environment without disrupting the proper operation of other close-by devices.

Electromagnetic Interference (EMI) stands for the electromagnetic energy a device emits, and it can cause problems in other close-by devices if too high.



There are several high spikes at low frequencies. Without the attenuator enabled in the LISN, I would have most likely damaged the signal analyzer's input stage.
