The electrician suggested and i complied with a whole house surge protector. He said it acts like a sponge and eventually will need replacing, but as for something coming into the house in the line, it is going to help me a lot, should that happen. On our two computers, i have a Ups. On my desk by the mac, I have a cyberpower that carries my stuff and the wife has a floor model that does her stuff. I have my computer, modem,power to my Console, Envoy and computer goodies there.
I think what the best plan is to trace the power back to where it gets into the house, and put in the whole house, then put in the UPS units. If you do go with a surge protector, I suggest getting a good one, such as a APC.
in any system, protection is only as good as the weakest link.
