Hi folks, I've done quite a bit of extensive reading on UPS in this forum and have decided to go with an APC SmartUPS to be safe and be without regrets. Sadly, there are no refurbs here in HK, so I must pay full price. Here is the HK site I am looking at: http://www.applesolution.com.hk/eng/p6.asp?ItemClass1=UPS&ItemClass2=APC&ItemClass3=SMART-UPS+TOWER I found the: APC Smart-UPS SC 1500VA 230V - 2U Rackmount/Tower - SC1500I for around $371USD, will it work well for my Mac Pro with 30" ACD, and a Drobo? I only need enough time for it to shut down, will it do so automatically via power management with OSX SL? The SUA1500 is $500 (a fair price) , and I don't see much of a difference between the two besides a slightly higher wattage on the SUA1500 and price tag, do you guys know of any differences? Thank you for any suggestions guys!
