Power Supply Characteristics
Here are the important characteristics of power supplies:
- Form factor
As with cases, the primary characteristic of a power supply is its form factor, which specifies dimensions and mounting hole locations, which in turn determine which case form factor(s) the power supply fits. Form factor also specifies the type of motherboard power connectors the power supply provides, which in turn determines the type(s) of motherboards the power supply supports. Table 26-1 lists compatibility of power supplies with cases.
