I am sure it doesn't hurt.. I would rather have the electrical surge stop before entering my pc. I hope you also use a surge protector. I always plug my pc's into one of those. I had my trip during a storm before. Once the power came back on all I had to do was press a reset button on the strip and power was let back through. Mine has a switch, a test/reset button, some lights and a speaker to let me know something is up. Oh and some phone jacks to protect the phones.
