Um, nope. If you try it, you will likely fry the supply because it will be grossly overloaded. If you have components rated for 240W, it is usually for a reason, such as cooling, max. currents of various components, etc.

Smart decision, especially when your electronics knowledge is limited. You could easily set your house on fire or give yourself or someone else a nasty shock by messing with stuff like this if you don't know what you are doing.

That sounds like a better device for the purpose. Just give it a lot of airflow - if it really has no fan, it will likely run hot.

X7JAY7X:
Sola makes industrial PSUs.  They are intended to be used in environments where there is little to no airflow (ie control panels).  In another life, I built industrial control panels and we used alot of Sola's.  They get warm but not hot.  They are alot better than any of the Chinese junk you buy most days.  The PSU on my printer lasted about 6 months only and already has issues.  It is garbage.
