The power spec has also been increased. A new version of the power supply connector that is used for graphics cards that need more power than the slot can deliver (sometimes called a PEG connector, for PCI-Express Graphics) has been introduced, changing from 6 pins to 8. A single x16 card may now draw up to 300 W of power (75 W from the slot itself, 150 W from an 8-pin PEG connector, 75 W from a second PEG connector), up from 225 W (75 W from the slot, 75 W each from 2 6-pin PEG connectors) or originally 150 W (75 W from the slot, 75 W from a 6-pin PEG connector).
