i have an apc xs1300 (780watt) in an i7-920, gtx470 non-sli non-overclocked system

at idle the pc draws around 158w which does not count a monitor. this number can easily triple during gaming sessions.

the apc states around 24 minutes on charge however i know from personal experience that in typical scenarios you are most likely looking at 6-12 minutes only.

keep in mind that gtx 680 gpus are are rated at around 150w idle and 300w peak. two of them at peak are capable of drawing 600w see link here for reference. your system will out draw mine and you are planning on using a smaller apc.

if your draw is more than the apc can handle (ie your whole system is at max load) the apc can not power the system and your pc will crash from loss of power. if your draw is at idle or moderate you will likely get some time to shut down first or time to wait out the power fluctuation.

it would be beneficial to get the largest apc you can. i do not think what you are planning to use is sufficient for your purposes. it may be for idle or moderate but in a worst case scenario it will fail. this does not count your monitor draw, speaker draw, or anything else you decide to plug into the apc.

you can look at your minimum draw numbers all you want but i am telling you that in the real world you need to look at the maximum values instead.
this is why i told you at minimum draw i would last 24min and on maximum i would last about 6-8.

i dont care about the 75w idle number as this does not represent the video cards you wish to add. even if with the video cards you idle less than 200w keep in mind that this is not a good number to base your load from. lets say you are out of the room for a few minutes or the system freezes up while trying to close a game because of a power outage. or lets say that you figure its just a temporary few minute outage and keep playing your battery is still going to drain very fast unless you get a properly sized system.

i'm not trying to force you to go out and buy a bigger upc. you can do what you want. all i am telling you is that you need to assume the worst. i've had power failures while under full load and 6-8 minutes is not a long time let alone the smaller timeframe you would get on a smaller unit.

You can overclock. The only way to pull maximum power is to run benchmarks that will keep both the CPU and GPU 100% busy. That rarely happens while using the system. Besides, you proabbly won't run benchmarks while there's a power outage (unless you want to test the PSU).
