I would have said that if you're looking at putting 4 HD5850's into one PC, then you probably need more than a 750W power supply. With a 750W, as long as it's highly efficient, then you could probably do 2 5850's, maybe 3 if you're lucky.

Best way to check all this out is to use a Power Angel / Power Meter to accurately see how much power is being used...

because from what i read that 1 5850 is "only" 150 watt
so 4 of them "is" 600 watt

I'm not sure what your build is but I get 2x 5850's and all the rest for around $350 - $400

It's my most recent thread Tongue
At my local hardware store it is around $350 and I should get 700 KH/s (litecoin) from it.

Is the 150W per card a figure that you've measured from your rig? Seems particularly low in my opinion..
