I have an ATX to AT converter that has leads that connect directly to an old style power button (toggle). However, the old AT PSU had 4 leads coming out of it and connecting to the power switch but the converter only has 2 leads.

I'm pretty sure, black goes on black but I'm unsure of the green lead on the converter. I assume it goes on what was the blue lead on the old AT PSU but I'd rather check to be sure.

Also a secondary question; as I understand it, old AT PSU's are (can be) a bit dangerous in that it actually has a live/hot wire going to the on/off switch. I assume that since this is ATX that such danger isn't present with this ATX/AT converter?

Any help much appreciated.
