    With that cpu and gpu's you are lucky to have more than one hour. The machine doesn't have igpu so you'll get more battery sucking components. I'd bet in one hour maximum in normal use

    I would guess that you might be able to get up to about 3 hours in energy saving mode and with undervolted CPU and GPU and brightness at mabye 40% tops.

    You might also try to make a special profile for the GPU with Nvidia inspector, that may also help. Still this is among the worst current laptops you can have when it comes to battery life as Clevo does not offer a manual GPU switch (imo this is a bad decision) or Optimus (probably a good decision as it affects performance). So the graphics card will kill that battery even if you manage to drastically reduce power consumption of the CPU and that runtime would only be for some office work/browsing/typing or watching a movie on the go.

    2-3 hours if ensure the gpus are forced into low idle (nvidia inspector can do this) and keep the CPU dynamically clocking and voltage is dynamic too.

    That might work for me, 3 hours would be ideal, my current laptop (HP Zbook G2) gives me 4 hours which is perfect for my classes, although moving it with two chargers will be hard lol

    It is only an estimate so better make your own tests before selling that Zbook.

    The way I see it the Zbook has three advantages:
    It runs longer
    It is lighter
    You can carry an add-on battery that will double its lifespan without much of an effort

    Of course it is also boring while the Clevo is cool :D

    With very light use I can get up to ca. 200 minutes on a comparable MSI Gt75 with a GTX1080 but when I say light I mean light so you can see that this is kind of an optimum scenario already :)

    As for power I am not familiar with the version with two power supplies but I am sure Meaker@Sager might be able to help in that regard as you may be fine with just one. FWIW I would think that for most use cases and with only one graphics card you should be able to use it with just one power supply especially with undervolted CPU and GPU but you'll have to measure power draw to verify that.

    I don't think there ever was officially a one PSU version.

    But wouldn't it be possible to connect just one of the two power bricks?
    From review pics that I have seen the connector should be the same?

    I read somewhere it was possible but the CPU would reduce it's clock speed to match the available psu output. I've done this on my Dell Precision M6400, it comes with a 210w wall adaptaer but I can use it with a 90w adapter but the CPU runs at 1.5GHz.
