Is this Coolermaster 600W PSU good?

[mk-ultra]

So my little brother's want a PC so I'm putting a budget build together really fast. Its a 600W Coolermaster (heres the link http://www.newegg.com/Product/Product.aspx?Item=N82E16817171036 ) It will be running a i5-750, and 6850. If I buy this power supply will it be able to crossfire the 6850 later down the road?

Thanks a bunch in advance.

No, it's a bit weak on the 12V rail, better get this one:

That Cooler Master psu got a very good review by a tough reviewer:

Is it enough for 2x5850 . . . maybe . . . but as mosox said at 40A (x 12V = 480W) its a little weak on the 12V rail. Many PSUs would have more than 480W out of 600W available from the 12V rail. But a PC with 2x5850 running Furmark peaked at 478W from the wall, which means less than 425W from the psu:

Since some of that power was not 12V power, there should be just enough to allow your cpu to run full out as well. But there isn't the margin we would recommend, so next year it might not be enough.

Either of the two PSUs recommended above would be much better.

How many rails does the seasonic have? I tried looking for it but can not find the answer.

Correction, I asked is it enough for 6850 in Crossfire.

How many rails does the seasonic have? I tried looking for it but can not find the answer.

It is a single rail split into two. Both the Seasonic and Corsair are better suited for crossfire since they have more power available on the +12 volt rail which counts for the GPU.

I have decided to just get the corsair 750W and to buy the 4650 for a graphics card, then in a month upgrade to a 6850. I am sure that the corsair 750W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006 will be able to run 6850 in crossfire, and overclock a AMD Phenome 1055T.

The Corsair 650 and Seasonic 620 would run that system just as well. Total system power consumption with 2xHD6850 running Furmark stress test 423watts http://www.anandtech.com/show/3987/amds-radeon-6870-6850-renewing-competition-in-the-midrange-market/20

Okay, I appreciate all the help.
