Then i think my +5v is okay, what i still need to know if 15a on +12v will be enough.
I got another one here which is +3.3v=25a, +5v=36a, +12v=15a, but this one had problems and i got it fixed, a little afraid of using it...
Oh, and it would be nice to know what devices uses +12v, +5v and +3.3v, so i could calculate here.
