Something you need to watch with a series configuration of ATX or similar power supplies. The ground is a common ground. If you measure from PSU common (black wires) to line input ground they are common to each other. Short of using an isolation transformer and eliminating the third wire ground I am not sure ATX type PSUs can be placed in a series configuration. Placing the low of the second supply in series with the high of the first may result in a dead short of the first. I may have this all wrong as it has been quite some time but you may want to be sure before investing in a few PSUs only to find it won't work. I see it as ATX output ground is common to ATX input ground (chassis ground) so thinking it would not work.
