All PSU's will have the same voltages, the question is how much actual electricity it can deliver at those voltages. The PSU I listed can deliver 26A of electricty at +12v. Most PSU's can only deliver 18A at +12v.
I'm going to assume you're not particularly familiar with how electricty works, and explain it a bit. The voltage of electricty is essentially what type of electricity it is. Most pieces of electronics can only use a certain voltage. So power supplies deliver various "types" (voltages) so components can use the appropriate type. +3.3v, +5v, +12v, etc. Amperes (Amps) is how much electricity can actually be delivered to actual components. So when the power supply lists +12v@26A, that means of the +12v type, it can deliver up to 26Amps worth of electricity. So if you have a lot of devices that use +12v electricity (which you probably do), then you need a lot of Amps that are +12v. If your PSU can only deliver +12v@18A, let's say, and your computer, under full load, drains 20A on the +12v line, then your computer won't get enough electricity, and probably crash. Usually when your computer is just idling, it doesn't use as many Amps as when you're playing games, so most PSU problems show up during games, or when your processor is under load.
