It might work and it might not depending on what you want from it.
Typical SMPS power supplies such as the ones pictured are inherently noisy as they have fast switching components. Also, daisy-chaining will possibly introduce more noise as there are ground loops formed between the pedals.
Another point is 11 A is complete overkill ? unless all 5 pedals are "Super-Ultra-Mega-Unthinkably-Insanely-Power-Hungry monstrous Digital pedals" of course.
Many off-the-shelf non-pedal power supplies are unregulated. These will provide the specified voltage when the specified current is drawn, but the voltage will likely be higher—often by several volts—for lower load currents. These power supplies sometimes have high voltage ripple which means more noise.
For the cleanest supplies, regulated supplies work best, however are inefficient at dissipating heat if not designed correctly and thus more expensive.
