OCP at +12V is set high (and even higher on the minor rails). Apparently, High Power thought it was designing a 1kW power supply and not a 500W one. So, the company decided to allow more than 40A at 3.3V. When we ran our OCP test on that rail, we noticed a smell coming from the PSU. We are pretty sure that if we applied 40A for much longer, the 3.3V VRM would eventually die.
Over-temperature protection is set pretty aggressively as well.

love4earthwk I'm afraid I can't find ETA-B and LAMBDA B- ratings in cybenetics sites.Reply

Aris_Mp there has been a change/refresh on the ratings. There is no more B, C, D ratings in the new ratings. The thresholds/ranges are exactly the same, just the naming scheme has been changed in some of the ratings. If you go to the ETA and LAMBDA pages you will find the new ratings.Reply -
Lutfij Good write up Aris! Should I revive my SFF system build, I'll know what to shoot for amongst a plethora of STX PUS's.Reply
