I do. My power would fluxuate enough that about once a week my computer would pop off. I have this
UPS by APC. APC has great products and the only reason I have this one is they ran a deal with it 50% off. I bet the other lower cost ones are fine too. I bought it when I had a PC, but I have my Mac hooked up to it now and haven't noticed any problems. Tell me about the PFC thing?? I don't know what that is or if this UPC is compatible.
edited to add-- looks like Office Max has 20% off with code SUMMERSAVE
