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 correctly 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.
Some spurs go over the limits. Not by far, though.
