A power supply is a device that supplies electrical energy to one or more electric loads. The term is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.
A power supply in guitar world are common use to supply electrical energy for guitar effects, gutar pedals. On the market we can find a lot of different type.....but the most popular are:
Voodoo Lab Pedal Power and Dunlop power brick.
Voodoo Lab Pedal Power
The Voodoo Lab Pedal Power AC is a pedalboard power supply designed to operate high current and AC powered pedal effects. Finally, a professional solution for powering tube overdrives, modeling pedals, or devices including Boomerang pedals, the Whammy, POD, Rotosphere and many others without wall warts.
Dunlop power brick
the Brick supplies predictable voltage at all times, keeping your effects consistent from show to show. Its FCLC (Foldback Current Limiting Circuit) provides ultimate protection against power shorts and overloads. Even at full load, you'll enjoy the quiet and cool operation of a fully regulated power supply. But since battery powered effects rarely exceed 30 milliamps each, you're not likely to use anywhere near the Brick's capacity of 1000 milliamps output! Power: Included ECB006 AC power adapter can use a wide range of international wall power from 100 to 240 volts, at 47 to 63 Hz. Supplied with U.S. plug

The Pedal Power AC provides two 9VAC and two selectable 9VAC or 12VAC outputs. Features include a toroidal transformer and completely isolated outputs to insure noise free operation. It comes complete with cables and detachable AC power cord. And like all Voodoo Lab products, the Pedal Power AC is hand made in the U.S.A. and carries a 5-year warranty.

Dunlop power brick VS Voodoo lab power supplies
Some review about:
There is one massive difference: the outlets of the PPII are individually isolated, while the outlets on the Brick are not isolated. If any of your pedals take a reverse-polarity plug, with non-isolated outlets all of your pedals now have the common mixed up with the live signal line, resulting in the potential for noise or even total failure. So while it is possible to use non-isolated outlets with no problem, the percentage of instances of noise and/or failure is higher than I will tolerate on my board. So I use the PPII. But the Brick is a lot cheaper, which is its only redeeming quality. It's just a daisy-chain in a box, so most budget-minded pedal users buy the 1-Spot or similar daisy chain PS cable, as it does the exact same job as the Brick but takes up much less space on the pedalboard. Again though, the 1-Spots etc. do not have isolated outlets.
If you don't have any pedals that take reverse-polarity plugs, of if the ones you do have don't happen to dump noise into the signal path or cause your other pedals to shut down, then you're a lucky person

both will fulfill your needs perfectly.. but the voodoo lab, like mentioned, sports isolated outputs, etc...

i dropped the extra bucks to upgrade from the brick to the pp2+.. well worth it for me, because of the pedals i was running...

In one sense, the two aren't really comparable. The Brick is essentially a 375mA daisy chain style 9vDC supply with seven outputs, and an additional 625mA available from three 18vDC outputs (which are not ground isolated from the 9 volt outputs, btw).
The Pedal Power 2+ is essentially eight completely separate power supplies in one box - six with 100mA max capability and two with 200-250mA max current. Since its outputs are completely isolated from each other, each pedal (or group of pedals, if you decide to daisy chain a couple from a single output, to allow for more than 8 pedals to be powered) will think they are completely alone. This is good for pedals that don't like to share the power (Line 6 Tonecore series, for instance) or pedals that simply can't share (positive ground fuzz pedals, for instance).
That's the basics of it - the PP2+ has a lot of different options too, like being able to individually switch the outputs to 12 volts DC, a special mode for Line 6 modeller pedals (DL-4 et al) and a "sag" mode to simulate a low battery (cool with fuzz pedals and some wahs). But at the core, the question is: do you need to fool the pedals into thinking they are alone (i.e. on their own internal battery), or will your rig stay quiet with a daisy-chain type setup?
If you don't get any additional noise with a regular daisy chain, chances are things will be quiet with the Brick as well. Current-wise, 375mA should be enough for the pedals you listed. But if you do get noise - or if you want to make sure you will never get noise due to daisy-chaining, regardless of what pedals you add in the future - the PP2+ will be immensely helpful.

The Voodoo Labs is much better (as you can dial in some parameter) but personally I love my DC brick. Since I got it it has been abused and used for like every day and still it works like a charm
I've been short circuiting stuff (bad things about making your own pedals) and still it won't budge.
And it has 3 18V outputs! which are much used on my board!
Shame is though that the 18V's are not protected. So if you short circuit them you have to repair that 18V output (by replacing a 1.8 ohm resistor)
----------------------------------------------------------------------------------------------------
the dc brick will work with both 9 volt and 18 volt. the only thing that you have to be careful with it the polarity. the pedal has to accept a plug that has a possitive barrel (the round part of the plug on the outside) and a negative pole (the rod on the inside of the plug. i use it with several different boss pedals, danelectro pedals, marshal pedals, crybaby wah pedal, fender tuner, univibe, and jekyl and hyde ultimate overdrive (silver). all of these pedals have a diagram of the polarity.
