I did a quick search, it seems that channelwell does the gs modelhttp://whirlpool.net.au/wiki/psu_manufacturers
According to that, the 750 is the only one made by seasonic, so i think ill probably invest the extra cash on that one
. That way i think im gonna be safe ? cause id like to have at least 1 dvd unit and im plugin an audio interface (usb) in the future.
