D.C. variable bench power supply unit, with a digital display showing current (left) and voltage (right), and three banana connectors (+, ground, -).Other power supplies may use the opposite order for indicators and connectors, and two different colours for the indicators.
The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.
Power supplies are categorized in various ways, including by functional features. For example, a regulated power supply is one that maintains constant output voltage or current despite variations in load current or input voltage.
