With parts picker go back in see if there any combo deals. If you have local micro center there CPU prices are low and they have combo discount on up and mb. Dropping down to a 4760k you should be fine.
along with the look at pcpartpicker.com the CX series from corsair are not as good as the rest of the models and 750 watts is more than needed even for an OC'd haswell and 770 SLI set up.
if you must shop @amazon
XFX PRO550W Core Edition 80+ Bronze $61.24
or if you are sure you are going SLI later than the 650 watt for $83.11 -before $10 rebate - would be better.
oh, and to echo what trademan stated, a 128gig SSD is pretty cheap. anymore there is no reason to get such a small SSD with what prices are now.
