How many volts should a power supply have?

Generally speaking, under no conditions should you exceed the maximum current rating of the supply on each output. So, in theory, from the numbers you give, a supply with two outputs, 30V rated at 14A or better and 5V rated at 0.5A or better would fill the need.

How much power does a 30V power supply need?

So, in theory, from the numbers you give, a supply with two outputs, 30V rated at 14A or better and 5V rated at 0.5A or better would fill the need. In some cases there may be a constraint on the total power, in which case you would check that the total power of 422.5W does not exceed the rated total power.

What type of outdoor outlet should I Choose?

The power requirement of the devices you plan to use also determines the type of outdoor outlet you should choose. If you're planning on operating high-wattage appliances, a higher amp outdoor outlet would be required. In dealing with outdoor electricity, safety is paramount. Here are some safety measures to consider:
