Question 1

Why does it say no to Crossfire support? The EA-650 supports Crossfire.

Accepted Answer

Honestly Its usually just marking buzz words. Its like how some psu say Haswell ready. Doesn't matter what cpu your using the psu is pretty much ready for anything that doesn't exceed its power limit. Being a platinum certified it has to be a quality component to get that rating. Just check to make sure you have enough pcie cables. You'll need two to four (possibly more depending on which particular gpu's your talking about). Most Gpu's use between one and two plugs. You'll also need to make sure your loads are balanced across the multiple rails. To much on one rail and even if you have excess capacity it will still shut down on you. In other words if you have two rail at 20a and one is using 21a and the other is only using 5a your psu will still shut down.

Question 2

Thanks.

Accepted Answer

Works just fine for Haswell.

Question 3

I have an older Antec Earthwatts EA-750 that is going out.  It is powering a first-gen Intel Core i7, motherboard, and the other components in my machine.  Will this newer Antec work for my system?

Accepted Answer

Hi Michael.  Not a problem.  That Antec EA-750 will work just fine.  Plenty of power and is compatible with earlier generations of motherboards and cpu's.  
Have a great day.

Question 4

Why is this listing ratings on both the 550W and 650W Power supplies when the "New arrival" is 750 watts?
Being new also means that the reviews are for an older model making this useless as a sales tool.

Accepted Answer

Ive had mine for a week now the New 750 watt. Very quite cant even hear it. Stays cool as well.
