Can I supply a single appliance using multiple power supplies?

For example if an appliance requires 100 watts of electricity, can I supply it with two power supplies, both of 50 watts?

100 Watt is not electricity but Power.

The answer to your question:

in theory yes

in practice some voltage/current conversion might be needed. It also depends on what devices you're using. How will you make sure equal power is drawn from both supplies ?
