Doesn't seem like your setup would approach the power consumption limit of the UPS. If your PC power supply has active Power Factor correction, then the power supply can demand about 600 watts from the UPS. Anymore and it may trip.

If your PC power supply doesn't have Active Power Factor correction, maybe as little as 500 watts and you'd be in trouble. But once again the components of your setup probably won't approach that. Count the monitor too.

A UPS ought to be able to handle it top power limit (600VA) for a minute or two before cutting power so there should be enough time to shut down. Of course at idle your PC won't be taking that much power except maybe the monitor
