I was mainly looking into that HX 750 and the AX series when I built my unit. I have an AX 850 and have had absolutely 0 issues with it. Wonderful piece of equipment. And since Seasonic built it, I would guess their PSU equivalents would be just as amazing.
Edit - And like Asmekial mentioned, the HX750 isn't fully modular. But in all honesty....is that such a bad thing? >.> The only non-modular cables are the motherboard and CPU power cables. The 2 you NEED to power your system...no matter what.
