Protection Features Evaluation

OCP at +12 V is set correctly, and the same goes for OCP at 3.3 V and OPP. Even the 5VSB rail's OCP is configured conservatively. In other PSUs, this rail can deliver almost double its nominal power before shutting down. Lastly, the 5 V rail's OCP is set at 139%, which is quite high. As this rail is often stressed by ARGB lighting, manufacturers try to bolster it.

OTP is set high, at 199 °C. I would feel more comfortable with an OTP threshold at 170–175 °C.

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.



The 3.3 V rail is always at a lower voltage than the other two rails. That said, the "PSU Off to Full Load" test results are problematic, again because of the huge drop at +12 V.

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.


There are some high EMI spikes with the average detector, but everything is fine with the Peak EMI detector.
