Modded PC power supply for charging

[Sammus]

Of course.. it seems obvious now lol. Both questions I asked. I really should of thought about that series connection thing. I've done plenty of these hack jobs before, usually just loading the 5v though

Cheers for clearing it up.

Thought as an electronics enthusiast with no formal training, I have another couple questions :)

You said you needed to draw about 1A for the feedback circuit to work properly? How come using diodes you only needed 250ma?

And if you have a psu with multiple 12V rails, can you parallel the rails to achieve the psu's total rated 12V power?
