Connecting Power Supplies in Series: Can It Be Done?

[bskramer]

is it possible to connect two computer power supplies together in series to increase the voltage like with batteries or does that not work with power supplies?

No, that would not work.

This is because each of the voltages you can get out of such a power supply has one side returned to ground.

So, on the two power supplies, all these ground points are joined together and you can't put them in series.
