    It does not.
    You have only so many choices to do some things and that might look similar but its not. For example the position of the Standby Rail. You can either put it close to the PFC Section or the 12V Rectifier Section. or left/right.
    But that's the same as older PSU with a "2 heatsink design", almost all look as similar as those two do...
    For example:
    https://img.tweakpc.de/image/dsc-4134-andere.Lgk
    https://img.tweakpc.de/image/dsc-4059-andere.LJD

    Both have Rectifier before PFC Coil, before main Bulk Cap, to the right the main Transformer.
    5V Standby is both times below the main transformer...

    Primary heatsink of this is similar to the Cougar GX-S:

    The Transformer of the Silverstone is in the middle, Focus on the right edge
    DC-DC of the silverstone is right next to the main Transformer, with solder joints above it. Focus has it behind the Transformer, parallel to the modular board.
    12V Rectifiers are cooled/heatsinked completely different, used Transformer, Coils completely different.

    Heck even the PFC Heatsink is on the opposite side of the PFC Section! Focus is left edge, Silverstone is a bit more to the middle.
    Primary Switcher on the Silverstone are heatsinked on the main Heatsink, Focus has seperate heatsinks for 12V Rectifier...

    And so on with many other things as well...

    Yeah but the Focus is the odd one out as full bridge is usually used in higher wattage designes such as 1000W or so, while lower wattage designs tend to have a half bridge.

    OK, OK.

    Maybe the Focus uses the same platform up to 1000w, so to optimize design costs?

    Should be ATX2700 of Enhance.
    Here is an another model which shares the platform.

    I can confirm OEM is Enhance. The KCC was in process when our customer there posted that page, the number should show correct information now.
