UPS Wattage: Battery Backed vs Surge Protected

[Grimm Spector]

If I have a hypothetical UPS that's running a system and peripherals, and the system is drawing say 500 Watts, and the UPS can run 600 Watts, and it's drawing from the Battery Backed Up plugs. Meanwhile there are periperhals/items on the surge protected plugs that are running say 200 Watts, putting us at a total of 700 Watts, will this be problematic? I'm not experienced with UPS systems. Logic tells me that it shouldn't be, since the surge protected ports should just be passing through the power while clamping the voltage, and filtering the noise. While only the battery backed up ports should need to worry about the inverter voltage from the batteries, and then only when it's in battery operation.

Am I right? If not why? Thanks!

If it's labelled surge protected only then it is often not part of the battery backup. As for the wattage rating, you can run 700 watts off a 600 watt. it's just not recommended and you will not get their estimated run-time.
