The better quality PSUs have surge (overvoltage) protection built into them anyway. I do like the additional outlets, but all you need for that is a power strip, which looks just like a surge suppressor. Much cheaper. I actually had a computer fry in 2007 during a thunderstorm that was plugged into a surge suppressor. PSU and motherboard both were useless, but it was a stock Compaq PSU of poor quality.
