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.
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.
A PMIC may include battery management, voltage regulation, and charging functions.It may include a DC to DC converter to allow dynamic voltage scaling.Some models are known to feature up to 95% power conversion efficiency.
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.
Logo. 80 Plus (trademarked 80 PLUS) is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer power supply units (PSUs). ...
The National Standardization Agency of Indonesia (Indonesian: Badan Standardisasi Nasional; BSN) is the International Organization for Standardization (ISO) member body for Indonesia. [1]
A capacitive power supply usually has a rectifier and filter to generate a direct current from the reduced alternating voltage. Such a supply comprises a capacitor, C1 whose reactance limits the current flowing through the rectifier bridge D1.
In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks.
