12V only power connector (labelled P1, though it is not compatible with the ATX 20 or 24 pin connector): This is a 10 or 16-pin Molex connector supplying the motherboard with three or six 12 V lines with common returns, a 'supply OK' signal, a 'PSU ON' signal and a 12 or 11 V auxiliary supply. One pin is left unused.
The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.
IC power-supply pins denote a voltage and current supply terminals in electric, electronics engineering, and in integrated circuit design. [a] Integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins ...
In electrical engineering, a common rail (shortened to COM) is a shared path between different electrical routes in an electrical circuit.For example, a device or circuit board might have a power rail or a ground rail, which components are attached to, so all the electrical charge flowing through different components is drawn from/collected into a single conductor line.
The ATX specification requires the power supply to produce three main outputs, +3.3 V, +5 V and +12 V. Low-power −12 V and +5 V SB (standby) supplies are also required. The −12 V supply is primarily used to provide the negative supply voltage for RS-232 ports and is also used by one pin on conventional PCI slots primarily to provide a ...
A voltage regulator module (VRM), sometimes called processor power module (PPM), is a buck converter that provides the microprocessor and chipset the appropriate supply voltage, converting +3.3 V, +5 V or +12 V to lower voltages required by the devices, allowing devices with different supply voltages be mounted on the same motherboard.
The power connector was typically the same 4-pin female Molex connector used in many other internal computer devices. The communication connectors on the drives were usually a 50 (for 8-bit SCSI) or 68 pin male (for 16-bit SCSI) " IDC header " which has two rows of pins, 0.1 inches apart.
Electric Ireland (Irish: Leictreachas Éireann) [1] [2] is an Irish utility company that supplies electricity and gas to business and residential customers in Ireland. It is the supply division of the Electricity Supply Board, the former monopoly electricity company in Ireland. The company now operates in an open market competing for the supply ...
