I ordered my parts and have mostly everything setup ( no graphics card and no memory yet :/ )
and i also added 2 500gb hdd's i had lying around, and i also just ordered a samsung 250gb sad and another 1tb hdd so i will have RAID 1 for 2 500gb ones and for 2 1tb ones and the ssd for start ups and stuff, that increased my power consumption i also have an msi gtx 770 and i was thinking on maybe sling or maybe even getting a single stronger card but i came across a problem i added the necessary components on pcpartpicker and my estimated wattage became 718 which cuts it pretty darn close to my 750w corsair cx750m 80+ bronze psu. What should i do?? Upgrading a psi when going sli seems to be kinda a lot of work unplugging everything unclipping cable ties that and this. So unless i REALLY have to i will, so i need the answer if 750w be cool with the setup.

My setup after upgrades: http://pcpartpicker.com/p/2h3u6

Nor would I.
If you are going to run triple monitor gaming, you will need some serious graphics capability.
sli GTX770 will probably do the job for you. You will need more than 750w to do the job.

If your upgrade plans are in the future, say a year out, then your options will likely change.
Maxwell and amd new gen cards are coming, and they are unlikely to need more than...

yes. always. but since you have a 770 already... it's cheaper to buy another 770 then to ditch it and get a 780 (ti) to come close to the speed the sli would get you. you could just get it and it may even work ok. considering it's so close to the limit i'd still plan for a new psu eventually.

Lol, I don't think I would want to sell a graphics card which took me a week and a half to get only to get a diferent me which jumps way out of my budget

It is not wrong to overprovision a psu. It will only use the wattage demanded of it.
As a bonus, it will operate more efficiently and quieter in the middle third of it's range.

I think I would defer on any preemptive changes until I needed them. Your 750W unit should suffice for now.

Yup, I guess I should wait and see, maybe some genius will come up with a powerful graphics card which won't consume much wattage. I can dream I can dream.

I calculated the power consumption of those system components and there's no way that it's 713 Watts.

I looked up the exact power consumption, where available, for each component and calculated the maximum power consumption to be less than 640 Watts and that's while running FurMark Stability Testing on the two MSI GeForce GTX 770 OC Twin Frozr IV and with all of the other components in use.

I wouldn't recommend using a low quality CX750M with that build though.
