Protection Features Evaluation

OCP at +12 V and OPP are correctly set, while the OCP triggering points are set high on the minor rails. The rest protection features are present and working.

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. We turn the unit off for our first measurement and switch it back on without a load on any of the rails.



The 3.3 V rail is always lower than the other two rails.

EMC Pre-Compliance Testing - Average and 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 it is too high.



The conducted EMI emissions are low.
