Protection Features Evaluation

Every PSU should be equipped with a set of protections, which will not only protect the PSU, but the whole system. You can learn more about PSU protections if you read the corresponding section of our "A Detailed Look Into PSUs" article.

In a snap, the most important protections for PSUs are the following:

Over Current Protection (OCP)
Over Power Protection (OPP)
Over Temperature Protection (OTP)
Over/Under Voltage Protection (OVP/UVP)
Short Circuit Protection (SCP)
No-load Operation (NLO)
Surge and Inrush Protection (SIP)

We should note here that OCP isn't usually offered in single +12V rail PSUs, especially high capacity ones. In such units, OPP takes over. OTP is very important, and we won't mess with OVP/UVP until we find a way to safely evaluate it.

Super Flower should take a look at the protection features on this platform, since several appear to be improperly configured. OCP on the minor rails is way too high, and the OTP's threshold should in our opinion be lower, at around 130 °C. Thankfully, OPP is set properly, and the power ok signal is accurate.
