What motherboards have 2 4-pin ATX hook ups

[alucardxva]

I just bought the sapphire radeon 7950 but my motherboard only has 1 4-pin ATX hook up an it needs 2 to power the card.. I have looked online an found--- ASUS Crosshair V Formula-Z AM3 AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Gaming Motherboard with 3-Way SLI/CrossFireX Support and UEFI BIOS---- it says it supports crossfire but i don't see how if it only has 1 4-pin ATX hook up... I'm a bit new to building computers/upgrading... so is it the motherboard that has the ATX hook up or is it the power source?

The Card gets power from the PSU (power supply) directly! http://www.tomshardware.com/forum/274745-31-step-step-guide-building
