OCP is sky-high at 12V, and the same goes for OPP. During the OCP evaluation, the PSU didn’t shut down, so I had to abort these tests not to be treated with fireworks. OCP is also high on the minor rails. Lastly, contrary to the 850W model, this one survived the over temperature protection evaluation.
