The folks around here who do government installations, schools, police, fire department, ect. have found that using surge protection of any kind in a series connection has caused early power supply failure to increase. They have no idea why but they do keep track of such things. They no longer do such things.
Of course I didn't adhere to the good advice.
I use to do two surge protectors in series and blew up a Antec 500W power supply. When I say blew up I mean the top of every capacitor blew off and fire shot out the back of the computer. I use a single surge protector now. One for each computer.
