I'd say a 500 or so. I have a similar setup(few more fans) and it works well for me, gives a good 10-15 min. run time.

thanks PSX. a UPS manufacturer's site recommended 1400va, and a minimum of 1000va for my system. were they trying to sell me what i don't need? i would like to hear from a UPS guru.
thanks.
