I might as well get the MSI Z97 Gaming 3 Intel, CXM Corsair builder series 750 semi-modular and a intel i5 4690k.
CXM is better than CX but still you can better PSU's for around the same price.
You should take a look at this list will give you a better idea--> http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html
The CXM is not any better quality than the CX.
CX430: Panasonic/Matsushita 180µF, 400V, 85°C capacitor on the primary and predominantly Samxon 105°C on the secondary with some Nippon Chemicon, Jun-fu and CapXon.
CX430M: Panasonic/Matsushita 180µF, 400V, 85°C capacitor on the primary and predominantly Teapo and CapXon 105°C on the secondary.
