Thread Starter 
Want to pull the trigger on one of these. I currently have the corsair hx850 but would like to go with the ax series because of its full modular and i want to get the sleeved cables.

Will an ax750 provide enough juice to run my components take a look at my sig rig for reference.

Even a quality 450W PSU would be enough, so yeah it would be plenty and it would be extreme overkill.  ;)

 

http://www.guru3d.com/article/geforce-gtx-680-review/9

 

Their test system pulled 307W from the wall outlet with one GTX 680 under full load.  The realistic power consumption that could potentially be pulled from the PSU with both the 680 and the CPU maxed out simultaneously would be about 425-450W maximum.

It's like advanced alien technology! :)

Yes AX750 is more than enough. Also its complete overkill, but it would run everything fine

If they are rated to pull 0.083A, then 6 would be about a half an amp.  Is that about 6W?  I haven't paid attention to the power draw of fans.  redface.gif

 

So yeah, you could get away with the 460W SeaSonic X-Series:

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151099

 

I'm only using this one as an example because it's fully modular and it has enough power.  ;)  However, I'm not telling you to get it because then what happens if you want to add a 2nd GTX 680?  If you did, then you would need at least a quality 550W power supply.

That'll still be pretty overkill, but yep!

 

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

 

The maximum amount of power that their system would pull from their PSU if they maxed out the CPU along with those two 680s is about 575W.  I don't know how much the 2500K pulls when overclocked to about 4.5 GHz, but I added 200W to their at-the-wall power draw bringing the at-the-wall power draw from 473W all the way to 673W, and then I multiplied that by .85 for 85% PSU efficiency and I got about 572W.

So now that you have that all figured out. What you planning on doing with your old crummy HX850??

EDIT:Phaedrus2129's psucalc says 520watts would be plenty for your system overclocked with the 670
