Modded PC power supply for charging

[Sammus]

Cool... my desktop just died and I pulled an Antec Tru430W out of it.. and to think I was just about to go and buy a new power supply :)

The one I have is rated to 28A@3.3V, 36A@5V and 20A@12V.

Do you know if there would there be any harm in connecting those three in series if I didn't pull more than 20A@20.3V? I'd like to have 400W available for my DUO at home.

I'm not sure I'll do your fancy mod, as I don't quote understand it. What are the diodes for? Is that so your only loading up the sense wire? and if so, why are there two?

Cheers

Sam
