OCP is correctly set at 12V, with a high difference between normal and hot conditions. The OCP triggering points on the minor rails are high, but this is not the problem. The problem is that the hot triggering points are similar (3.3V) or higher (5V) than those at normal temperatures. The other way should be the case, since the PSU is stressed more under high temperatures. Moreover, the over power protection is highly set but drops notably at high temperatures, to effectively protect the PSU. All other essential protection features are present, and soon enough, I will add more to my test sessions.

  1. Good day Aris,
    Sorry to bother you, but I need some help choosing a PSU. After reviewing all the information on your website, I am still unsure which one to go for—the RM750x or the Power Zone 2 750W from Be Quiet!. My main concern is the PSU mounting in my PC case, which is side-mounted at the top corner. With the RM750x, the power cord connector placement means that if I face the fan inside the case, it could affect airflow. If I face the fan outside, the power cord would have to bend awkwardly.
    On the other hand, the Power Zone 2 seems like it would fit better with the fan facing outside, avoiding the bent cable issue. Given these constraints, what would you suggest in this situation?

    Thank you for your time and help.

  2. Aris Did all internal power supply components required for tearing down for a documentation or just some sample you did it for a tearing down, because some cybenetics doesn’t have internal info like a Bulk caps, MOSFET, IC, switcher, etc

    1. If you ask whether all Cyben reports have part analysis, unfortunately, not for older samples. But for newer ones we try to have them on all.
