The 12V rail’s OCP triggering points are set below 130%, but not correctly set, since under high temperatures, not only is the triggering point lower than at standard temperatures, but it is also higher! This doesn’t make sense since the PSU is stressed more at high temperatures. Moreover, the over power protection triggering points are identical, only 1% difference, but they are at least conservatively set.

On the minor rails, the OCP triggering points are set sky-high, and to add insult to injury, are similar under normal and high temperatures. The rest of the essential protection features are present except for fan failure, which should be present in such an expensive PSU utilizing an MCU.

  1. *moSfets !

    ” It features GaN MODFETs…”
    “… high-end ATX v3.1 compliant PSU using a Seasonic platform with MODFETs…”

  2. I’m considering this or MSI MEG AI1600T or Seasonic Prime TX ATX3.1 1300W. 5090/R7 9800X3D what would you suggest?

  3. Aris i’ve seen that Cougar GLE1000/1200 cybenetics the data OEM said it was CE-Link, but i was bought the GLE 1000 and they said on a label it was Compucase or HEC, which it’s true about this CE-Link or HEC/Compucase ?

    1. As I remember I asked Cougar about the OEM and they told me CE-Link, because at some point it is difficult to recognize who actually made the PSU.
