===== Slot power ===== <!-- Please DO NOT add the claim that the PCI express 2.x standard adds support for up to 150 W from the slot itself without a very good reference. While several references make the claim, particularly around the time of release, other references particularly those relying on the spec. dispute this. See the talk page discussion dated November 2012 for details. --> All PCI express cards may consume up to {{val|3|ul=A}} at {{val|+3.3|ul=V}} ({{val|9.9|ul=W}}). The amount of +12 V and total power they may consume depends on the form factor and the role of the card:<ref name="CEM1.1" />{{rp|35β36}}<ref name="jArAO" /><ref>''PCI Express Base Specification, Revision 1.1'' Page 332</ref> * x1 cards are limited to 0.5 A at +12{{nbsp}}V (6 W) and 10 W combined. * x4 and wider cards are limited to 2.1 A at +12{{nbsp}}V (25 W) and 25 W combined. * A full-sized x1 card may draw up to the 25 W limits after initialization and software configuration as a high-power device. * A full-sized x16 graphics card may draw up to 5.5 A at +12{{nbsp}}V (66 W) and 75 W combined after initialization and software configuration as a high-power device.<ref name="PCIe card 2" />{{rp|38β39}}
