6 Rails, but they're 38A apiece. I don't see anything wrong with that.

Any PSU I have used with multiple rails has caused me problems.. or died...

Just bad personal experience I guess.

You really do not want a multi rail power supply, unless it is crowbar protected or VERY expensively designed.
If one of the rails goes down, then your very expensive hardware is toast as the other rails suddenly become biased against the missing rail.

in the case of a -12 +12 , it can become +/- 24v locally in the hardware ,but still look like +/- 12v to the external circuit regulator!!!!

I have a multi rail 1000 watt here and it works.. Turns on.... if you use a certain pci-e cable it shuts off...

if I use it for normal PC use it's fine.....
