Then here are some ~650W modular power supplies that I recommend just from Newegg alone.  All of these have enough power to run your system if it had two GTX 680s in it (some don't have enough PCI-E connectors thereby requiring the use of adapters that are usually included with video cards):

 

 

 

If it were my money, then I would get the 650W Rosewill CAPSTONE!  It has four PCI-E cables that are 6+2 Pin each (which is nice for the sake of compatibility), and it includes a free 16 GB Flash Drive.  The other PSUs are excellent too, but this one seems to have it all.

 

 

Edit:  Of course, there's the 750W modular Rosewill CAPSTONE for $87.99 shipped with the promo code EMCNANC35!

http://www.guru3d.com/article/geforce-gtx-680-sli-review/4

Their test system pulled 473W with two GTX 680s in SLi under full load.  The CPU was idling during the test, so we can add about 200W just for good measure making for a power draw of 673W being pulled from the wall outlet.  So if the PSU were 85% efficient and pulling 673W from the wall outlet, then that would mean the system would be pulling no more than about 575W from the PSU.  However, I added 200W which is a bit on the ridiculous side, even when overclocking the 3770K.  wink.gif  A much more realistic figure is about 150W which changes 575W to about 525W.  The only way we'd see a power draw this high is if the CPU and the video cards are under full load simultaneously, but that doesn't happen very often (if ever).

So yeah, a quality PSU that has a capacity of 550-650W is enough.

After looking at that review, they say that for SLI 680s they recommend at least 750?

They are taking into consideration the possible ownership or purchase of a generic 750W power supply (this ensures that they don't receive complaints from anyone about their PSU not having enough power).  Many generic 750W power supplies would have a +12V capacity of 500-525W or less (usually less).  They could say "650W", but then they'd have to explain what they mean.  So that's where sites like Overclock.net come in handy.  :)

 

Here are the +12V capacities of the PSUs I recommended:

 

 

 

Most of these have a peak capacity that easily either meets or exceeds 750W.  The 700W LEPA G700-MA likely has a peak capacity that exceeds 800W.

 

This is one reason why these PSUs can be recommended.  The other reason is, again, the 575W maximum possible draw on the PSU that I discovered and discussed above (which is why they generically recommend a 750W power supply, and it's why I specifically recommend these quality 650W power supplies).

Here are the +12V capacities of the PSUs I recommended:


[*] 650W SeaSonic M12II for $115.17 after shipping:  636W +12V capacity
[*] Corsair TX650M for $115.98 after shipping (comes with $10 Mail-In Rebate):  648W +12V capacity
[*] 650W NZXT HALE82 for $115.98 after shipping (comes with a $30 Mail-In Rebate):  636W +12V capacity
[*] 650W LEPA G Series for $114.99 shipped (comes with a $15 Mail-In Rebate):  648W +12V capacity
[*] Corsair HX650 for $119.99 shipped (comes with a $10 Mail-In Rebate):  624W +12V capacity
[*] 650W SeaSonic G Series for $135.17 after shipping:  648W +12V capacity
[*] 650W SeaSonic X-Series for $139.99 shipped:  648W +12V capacity
[*] LEPA G700-MA (700W) for $150.98 after shipping:  696W +12V capacity
[*] 650W FSP AURUM GOLD for $148.98 after shipping (comes with a $15 Mail-In Rebate):  600W +12V capacity
[*] Corsair AX650 for $155.98 after shipping (comes with a $15 Mail-In Rebate, but internally this PSU is the 650W SeaSonic X-Series):  648W +12V capacity
[*] 650W KINGWIN Lazer Platinum for $175.98 after shipping:  648W +12V capacity



Most of these have a peak capacity that easily either meets or exceeds 750W.  The 700W LEPA G700-MA likely has a peak capacity that exceeds 800W.

This is one reason why these PSUs can be recommended.  The other reason is, again, the 575W maximum possible draw on the PSU that I discovered and discussed above (which is why they generically recommend a 750W power supply, and it's why I specifically recommend these quality 650W power supplies).
Thank you so much! You have been a great help! I just ordered my new power supply. Went with the 750W modular Rosewill CAPSTONE!
