GPU / Power Supply Question

[smendlik]

A quick question, if I want to run 2 video cards, one needs 350w of power and the other 400w, do I need a 750w power supply or just enough to cover the card with the highest demand (400w)?

I suggest a 1000 watt Power Supply since you might be running both cards and extra fans, the motherboard, cpu processor, hard drives, and cd/dvd drives all together. Better to have more than not enough...
