What you have is clearly an unregulated supply, which will reach the rated voltage only at, or near, full load. Most electronic devices are spec'd at +/- either 5% or 10% on supply voltage, and you are well over that on all but the 5V output. In particular, most ICs are spec'd for no more than +/-10%, and are VERY likely to be damaged if this is exceeded. I would not use that supply to directly power any electronics, without knowing that they can tolerate the over-voltage.
Either get another supply, or add regulators to that one (and this is not really practical, or cost-effective at those current levels....).
