BGE's take on the Quadra 900/950 ATX PSU Mod

Success! The switch fits the opening!


It almost looks like it's meant to be there from the factory.

There's only one small inconvenience: the tabs on the switch are slightly narrower compared to the ones Apple/Delta used. In order to keep things as simple as possible (and to prevent permanent modifications), wires will be soldered directly to the terminals. Spade connectors (4) will then be used to connect the switch to the AC board.

I somehow missed the last update. This is exactly what I want to do with mine (add a switch) - for now I left that hole empty after doing my conversion. Keen to hear how yours is going.
