80 Plus
80 Plus is a certification of efficiency of the AC to DC conversion within a PSU. 80 Plus Certification does not mean a power supply will be 80%+ efficient 100% of the time; in fact, the 80 Plus certification only requires certain levels of efficiency at certain load levels. We have embedded a table below.
PSU Form Factor
These standards define everything from the size and shape of the PSU to its electrical requirements and output. Power supply form factors have been standardized in order to increase compatibility. ATX PS/2 is by far the most popular form factor, and will fit in the vast majority of cases. ATX PS/3 is a compatible with PS/2, but is slightly shorter in depth. ATX PS/3 PSUs are less common and used more in smaller cases such as mATX cases.
Voltage Switch
Different regions have differing AC voltages (from wall outlets). The United States and a few other countries use ~120v, whereas the rest of the world mostly uses ~220v.
