Hi, I am thinking of building a new computer and am very please with these components. However, it is the power supply that troubles me. My main concern is if a CX series would be recommended with this build that I have. Thank you.
The CX750 IS A GREAT choice and is Haswell certified.
The XFX 550w isn't Certified for Haswell
The XFX 550w is tier 2
Can you please tell me the difference between a TX series and a CX? Thanks.
CX series is known as the "builder" series and is about as close to entry level as Corsair offers. The TX series is their enthusiast series which are built to stricter standards. Above that is HX which is their professional series, and at the top is the AX series which is what they call "professional gold", several of which reach 80Plus Platinum ratings. There's also a VS series for european systems only and a new GS series for gaming which is very oddly positioned from a marketing perspective.
In particular, the manufactures are occasionally different. Most of the AX series is manufactured by Flextronics and Seasonic (with Seasonic being one of the best SMPS manufactures out there, and Flextronics usually working in the enterprise domain), most of the TX V2 series are also manufactured by Seasonic. The rest, including the CX, TX (non V2), HX, and CX V2 are manufactured by CWT. CWT can do some impressive work, but in my profesional opinion they're not as good as Seasonic.
