UPS for 1000w PSU

[BaDDaSS]

So I bought the Coolermaster 1000w Modular PSU.

I want a UPS that will just give me enough time for the PC to shut down in the event of a power failure.

Would something like this cover me; http://www.overclockers.co.uk/showproduct.php?prodid=UP-022-AP&groupid=702&catid=55&subcat=

I know the output isn't 1000w, but I've been told it doesn't have to be? Because I won't be running off the UPS for a long period, just long enough for a quick shutdown.

So while the PC is plugged in and running, would it be getting full power? Or would it be limited to the UPS it is running through?

A PSU only provides the power it needs, so your 1000W PSU will hopefully never be providing 1000W....

That being said, under normal conditions that UPS will be fine..It shows an uptime of 4.2 minutes at a 330w draw..... so unless your drawing crazy power, you would have more than enough time for a shutdown.
