How to determine a good power supply? Which ones are best for me?

Ok, so I'm preparing to build a mid-high end gaming PC with an Xeon 1230v3, i5 4670k, or i5 4690k, a Z97 Mobo like MSI Gaming 3, 5 or 7, and a Nvidia GTX 760.
I've been looking at PSUs for a while now, but all the ones recommended to people are $130 and up, some even $230. I was hoping for 700w or 750w, but would like to spend less than $100, or $120 at most if I can't get it for less.

I was under the impression one could get a good quality PSU for less than $100 without an issue, but now I'm not so sure, and although I can afford a higher costing one, I would like to avoid increasing the price of PC, which now sits at approx. $1,400 Canadian (after our silly 13% tax rate).

The PSU in that build is a Corsair CX750M, it's $100 CAD and has 750w, allowing for future SLI and overclocking. It seems good for me, and price is decent in my books, but I'm also completely clueless in this field. Is this one any good? If not, what should I look for? I would like quality and reliability, but also not super expensive. What do people normally buy for gaming builds? I will only be gaming on one monitor, 720p to start with and later 1080p if I decide to make the jump up. I will only be doing one task at a time, I'm not really much of a multi-tasker, and will be using the PC for gaming 90%-95% of the time, if not 100%.

Thank you for your time and consideration.

    That is a good psu and will suit your needs. For gaming go with the i5 cpu. Also you could go with the i5-4670k and Z87 mobo to save money.

    It's good enough quality and should be reliable? Why do people recommend $130+ psus, and sometimes above $200? Ya, I'm leaning towards the i5, but I also wanted a Z97 for the Haswell Refresh lines, and the Broadwell lines of CPUs. Furthermore, the Z97s I'm looking at are around the same price for some Asus Mobos like the Z87 Gryphon that I was considering for a bit. Other than being bigger, they seem to be just as good as the Gryphon, but are for the "newer" generation. Still, I won't write Z87s off.
  3. For your case that psu would be sufficient. IF you were to go with say 2 x R9 290s and overclocked everything, then yes you are going to need a bigger, better psu.

    Wow.... More than 750w seems crazy to me.
