As I was saying, is there any detriment to feeding the A1200 with power, from the same power supply, via two different paths?

EDIT: I don't actually have any plug-in PSU's for the additional devices anyway, so I need to power them from somewhere...


 It's OK to feed the motherboard via the standard socket and the floppy power pin header (if the PSU is the same). I do it to mine and it runs OK, with little voltage dropout. Specially heavy power-hungry accelerators would be benefited for a loss-less power rail (like 040 accelerators or PPC).

 For feed other devices, just put (or leave untouched) the original 4-ways Molex connectors.

 Trust me, I have a degree in electricity!

 @Moto: the Amiga don't use the 3.3V rail anywhere! Just +5V, +12V and -12V.

Goodbye people.

I\'ll pop on from time to time, RL is acting up.

 I am aware of the redundant power rail issue.

 But it appears only in high current/high frequency devices (like peecees, nowadays).

 And this method alleviates the current inside the motherboard, even with the cycling power issue.
