No it is not safe to run a system (well except for an old IBM PC, XT, or AT) on such a small power supply.
While it may function, you are going to be overheating and stressing the power supply. When the supply fails, it may damage or destroy the other components.
Other than space or weight, there is no good reason to use a small power supply.
A larger power supply will not use much more power running this system than the 100 or so watts the system will draw. Even if you were to use a 500 watt supply, it would not use much more power than the specified 128 watt.
The reason is that switch mode power supplies have very little wasted power. They generally run at over 80% efficiency. If your computer at idle only uses 80 watts, the power supply will consume about 20 watts of power to deliver 80 watts to the system.
