Personally I would go with about a 600w PSU for that build, you are not leaving yourself a lot of headroom especially if you start overclocking that processor. You'll be running a 450w power supply flat out almost all the time to power that. Even a quality power supply will have it's life shortened under constant load not to mention the heat generation.
Use this http://www.extreme.outervision.com/psucalculatorlite.jsp to give you a rough idea of how much power your machine will draw, and then add at least 100w on top of that.

It's an H81 chipset with a non-k cpu, won't be doing any overclocking. 500-550W should be plenty.

Ah for some reason I didn't read the specs correctly, however a GTX 760 still pulls 160w on it's own under full load. This is only my opinion of course but I really think when you are running a gaming graphics card you really should look at a minimum of 600w. But that's just me, I'd much rather have too much output than not enough. Why put the PSU under more load and generate more heat?

i5 4670 doesn't consume much power...
if you have only 1 hdd then your 450W is more than enough for 760..
nvidia recommends 500W because nvidia is assuming that you have 8-core amd cpu and 2 hdds..
don't listen to nvidia's recommendations....

Yes but the cost difference between 450w and 600 - 650w is not massive and I think it's worth it. I'm a strong advocate of only using what you need, and not paying over the odds and the build that the OP is going with is a shining example of that. However, after recent experiences with power supplies and building some machines for other people I am also a strong advocate of a decent power supply. If you buy a power supply that meets your requirements you will be constantly running that power supply over 50% of it's output. A higher rated power supply will only draw the power it needs so costs no more to run but it would in theory be more effecient if it is running at say 30% capacity and will produce less heat.
