Why does he need a minimum 10amps?

He needs a minimum of 10 amps because he is considering using the DuraTrax IntelliPeak ICE Charger which is a 10 amp charger.
I bought a new 500W ATX PC power supply from Comp USA for $19.95 (after rebates) and converted it for use with my ICE charger. See photo below.
I connected banana jacks to three of the positive voltage outputs, 12v@18a, 5v@36a, and 3.3v@22a. I also added a green LED pwr-on indicator. The power supply has a power switch on it's case.
It provides smooth, well regulated, quiet (quiet fan) power to my ICE charger.
