OCP at 12V is conservatively set; the same goes for the over power protection. On the other hand, the OCP triggering points are sky-high on the minor rails and have a relatively small difference between cold and hot conditions, so they are not that effective.
The primary issue is that we tried two samples from this line at “-12V to Earth” SCP, and both died, meaning there is something wrong with this rail. CWT should completely remove it since it is optional, and no PC part requires it anymore.

Hi! Will ask them to send me some!
Hi Aris, can you review the FSP Vita GM 850W please. It is one of the few ATX 3.1 PSUs.
