    For example, in North America, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volt transformer. This system is able to concurrently provide 240 volts and 120 volts. Consequently, this allows homeowners to wire up both 240 V and 120 V circuits as they wish (as regulated by local building codes).

    The ATX connector provides multiple wires and power connections for the 3.3 V supply, because it is most sensitive to voltage drop in the supply connections. Another ATX addition was the +5 V SB (standby) rail for providing a small amount of standby power , even when the computer was nominally "off".

    The connector first appeared in the Nvidia RTX 40 GPUs. [3] [4] The prior Nvidia RTX 30 series introduced a similar, proprietary connector in the "Founder's Edition" cards, which also uses an arrangement of twelve pins for power, but did not have the sense pins, except for the connector on the founders edition RTX 3090 Ti (though not present on the adapter supplied with those cards.)
