Power failure using simple mode transaction Log

Any comments about what happens when we get a power failure using simple mod
e
transaction Log?
I had 3 Power failure and there has not been any problems with the data.
The auto recuperation informs that 5343 rows where commited and 0 rolled bac
k.
Can I expect this behaviour in the future? (another power failure).
Note that I have a UPS, but I didn't have time to shutdown properly.Run DBCC CHECKDB if you haven't already.
You should configure your UPS to shutdown the server automatically after N
minutes of power failure.

--|||If you have hardware write cache, you need to make sure it is properly backe
d up, and follows a
certain set of rules. If it does, the database should not go corrupt because
of a power failure. If
you don't have hardware write cache, then you probably don't have battery ba
ckup and you can see a
torn page. See http://www.microsoft.com/technet/pr...>
