With any power supply the load will only consume what it requires
Exactly like a lamp socket at your house.
If you put in a 10 watt bulb, it will consume only 10 watts.
If you put in a 100 wattt bulb it will consume 100 watts.
However since power supplies are not 100 percent efficient, there are losses in the power supply and it will consume some energy as well as the load, which shows up as heat.
The more power consumed the greater the heat loss inside the power supply and the hotter it gets.
As an example if you take the maximum capacity from a computer power supply it will get very hot and the built in fan cools it down.
If the fan stopped, the supply would quickly overheat and burn out.
With a computer power supply, for every watt taken by the load a quarter of a watt is wasted inside the power supply.
So to deliver 25 watts to a load costs an additional 6 watts.

am i right or am i wrong?
so i am right saying that a power supply absorbs watts, but at the same time i shouldn't say this?
this panel freaks me out guys!

JP, you were correct...
That is why I said "about 25 watts" at the end... my apologies, i should have explained further.

OLD AT PSU
I have moved on and will now be using the above PSU to power my fans. The question is: Can I just connect the black and white wires where the switch usually goes to by-pass the need for a switch at this point? Everything I have learn thus far says "yes" but I just want to confirm this before I proceed. The reason I am unsure is because of the multitude of other wires (blue, brown, etc.).

Re: OLD AT PSU
Hello,
Please before you mess around with these wires. Figure out how much voltage is coming out of these wires. Electricity can be very dangerous and fatal if not understood. Obviously you sound unsure of what you are doing in this scenario. I would readup and learn first, before taking anything apart.
BTW. I checked the connector you were mentionning....
It has, black, blue , brown and white wires going to it.
1 = black
2 = brown
3 = blue
4 = white
diagram:
---- 3 --- 1 |
---- 2 --- 4 |
when you flip the switch it connects 1 and 3 together and 2 and 4 together.
theres 120 volts running through there, and i once had the accident of touching it with pliers. It sparked, blew a fuse and my job and i toasted a floppy drive. I would use this switch and not bypass it.
Edit: changed 3 from 5....
