^+1 on the NZXT PSU as I have that very same one and so far has been giving me no problems and looks really good quality-wise. It is half modular but you most likely will need the cables they have fixed in anyways so it won't be a big deal to have it half-modular. Anyways, the cables are black too so it will look nice and yes it is very rock solid as it has a 100% Japanese capacitor and is Seasonic built.
The link provided above however is for the 650W model.
Here is the 750W one:http://www.newegg.com/Product/Product.aspx?Item=N82E16817116015
If you want, there is also a HALE90 series NZXT PSU that is even higher rated in quality and energy usage. It will cost more but I think it is worth it. Take a look:http://www.newegg.com/Product/Product.aspx?Item=N82E16817116011
