Hello,
I am finally going to complete my 8-bit breadboard computer ( just the control logic left ). I am not dealt with this issue of power distribution across the breadboard. I have tried the following method and would love to hear some recommendations to it :
I took my cell-phone charger | OUTPUT - 5.00 V 2A | and connected it onto the breadboard by soldering with some header pins. The LED's did glow somewhat better than before, So I tried connecting another power supply which I got it additionally when purchasing the breadboard. Its called a 'Power Module' and it gives me about 5V and then the LED's glow a lot better but could still be improved.....

Probably the best tip is to calculate your load. Add up the draw of all your components and use a PS that is spec'd for 50% over that.
If you must use USB cell phone chargers, get a USB connector. Breakouts for the jack are available. This is one example:

You might have to supply resistors to tell the charger to give you full/more power.

This is a perfect opportunity to use your DMM to measure the current required of the PS. While you're at it, measure the voltage while drawing full current.
