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.
Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s. [1] [2] First used in home appliances, other industries soon began designing it into their products from automobiles to vending machines to minicomputers.
Microplastics shed from plastic products like clothing and packaging are ending up in the fish we eat, according to researchers from Portland State University (PSU). The findings of the study ...
The ATX specification defines the Power-Good signal as a +5-volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized.
DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).
Penn State will play its first ever College Football Playoff game when it takes on the SMU Mustangs in the first round on Saturday. The Nittany Lions will play the game at home in Beaver Stadium.
