My friend has a OCZ ModXStream 700W 80PLUS (80% efficient) power supply and an HD 6870 1GB graphics card. He plays a lot of games on his computer. My friend's planning on getting a second HD 6870 1GB graphics card for his computer. Would my friend need to get a bigger power supply, or will the 700W power supply suffice? He has an i5-2320, 4 hard drives, and like 7 fans in his computer, if that helps.

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)

Little wiggle room either way for different iterations of the reference card, but in a nutshell your friend should be fine.

Sorry, he has a 700W power supply, not 750W, and it's still 80 PLUS ($80 efficient.)
