![]() You try to avoid theoretical maximums for production. Typically, power supplies supplied half that for peripherals (5A for both comes to mind). With the 14 AWG cable, you could get 11A on 12V circuit (Pins 1 and 2), 132W, and 11A on 5V circuit (Pins 3 and 4), 55W. And OP 44A/connector.įrom SuperUser (but no reference to external source) Is this a floppy disk connector to the power supply?: Increase wire size to 14 AWG and you do get 11A/pin. Odds are that no actual circuit will have 18A sourced due to other factors. There are other factors: Ambient Temperature. All applications should be tested by the end user.Īs in designer is responsibe. are intended to be a guide in the selection of a connector family. That is 18A supplied and 18A sunk (Ground). 36A per connector theoretical maximum, if 105☌ and 30☌ are maintained. With every circuit energized, for a 4 in-line connector, with 18 AWG wire is 9A/pin. Derating connector due to adjacent conductors. For technical drawings and 3-D models, click on a part. A locking tab keeps them securely in place when mated. Each set includes one male plug and one female socket. All come assembled with wire leads already installed so they can be quickly added to existing wiring systems. Table shows number of circuits vs size of wire. A sealed polystyrene plastic housing protects connectors from weather. The maximum current that can be carried is a function of the maximum temperature of the housing (105☌) and the maximum temperature of individual connection (30☌) (and maximum temperature of wire insulation) (and length of wire) (and ambient temperature). The problem is a little bit more complicated than that. So 4 pins at 11A/pin leads to the 44A of OP. Budget SMPS have less number of these connectors but high-end Power supplies have a higher number.Max. Note: The number and availability of these connectors vary and depend upon the model and brand of the SMPS. The new PCI Express 8 Pin cable can provide a maximum of 150 Watts power which is double that of the PCI Express 6 Pin cable i.e. Older mid to high-end graphics card comes with PCI-e 6 Pin slot while the newer high-end graphics comes with PCI-e 8 Pin slot. Budget and low-end graphics cards do not need them as they draw their power from the motherboard PCI-Express x16 slot only. PCI-e 6 Pin or PCI-e 6+2 Pin are 12 Volt Connectors that are used to provide power to mid to high range graphics cards that require extra amount of power for their working. ![]() by the use of converters or adapters e.g. You can also use this Molex 4 pin connector to power other devices like SATA devices, Graphics cards etc. Peripheral 4 Pin Molex Connector is used to provide power to IDE devices and other peripherals like Fans, case lights etc. Floppy Drives are not being used commonly, but in some cases they can prove very useful. This 4 pin power connector is used to power floppy drives. This power connector is used to power up SATA devices that mostly include Hard Disks, DVD Writers / Drives. Some motherboards have 4 pins 12V CPU socket and some have 8 pins 12V socket, therefore most of the good power supplies come with 8-pin (4 + 4) detachable connectors which can be split into two 4 pin connectors. This is the 12 Volt connector that supplies power to your CPU or Processor. Therefore nowadays all the SMPS comes with 24 pin detachable connector (20 + 4) that can be split into 20 pin and 4 pin cables. Earlier motherboards have 20 pin sockets only but now modern-day motherboards require 24-pin power connectors. This is the main ATX connector that supplies power to your motherboard and other components like RAM, Low-end graphics card, PCI cards that are connected to your motherboard. SMPS or PSU Connectors 20 + 4 Pin ATX / Motherboard Connector
