Not necessarily as your system isn't using 400W, that just means your psu could support UP TO 400W. And that's the same case with a UPS. 400W means UP TO 400W. Even though your system is maybe using around 200W, the higher the watts the UPS is rated at, the longer it would be able to run your system without power. So a 400W UPS would generally run your system longer than a 200W UPS. But other than that, you'd just have to read into a specific UPS to see how long it's expected to last @ a certain number of Watts and so on.
