The Power Supply Chart




Power Supply Buying Guide

Efficiency
The efficiency on the chart is based on specifications from manufacturers, actual results may vary.

Active PFC
Power Factor Correction (PFC) allows power distribution to operate at its maximum efficiency. The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able to generate a theoretical power factor of over 95%. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage. Since Active PFC is the more complex method of Power Factor Correction, it is more expensive to produce an Active PFC power supply.

80 PLUS
The 80 PLUS performance specification requires power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies and creates a unique market differentiation opportunity for power supply and computer manufacturers.

SLI Ready
SLI stands for "Scalable Link Interface." SLI is a technology developed by NVIDIA that allows multiple graphics cards to work together in a single computer system. This enables faster graphics performance than what is possible with a single card. SLI Ready means this product supports SLI technology.

The list for non modular psu will be longer so it will take a longer time for me to compile.

The reason why I started with modular psu is that most people prefer it for easier cable management.
