Protection Features Evaluation

The OCP is properly set at +12V and +5V, and the same goes for OPP. Over temperature protection is also working well, but the power ok signal is inaccurate, which is a great shame, especially for such a high-end PSU.

DC Power Sequencing

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