need your suggestion and advice in my first build

Looks decent, except that I would choose a better-quality power supply unit than the one that you chose. You see, that Thermaltake Smart is only an 80-Plus plain certified PSU with all of the cables - both necessary and redundant - permanently attached. This is a sign of a relatively low-quality power supply unit to begin with. Despite its "600W" rating, it might only handle 450 to 500 watts before shutting itself down to save the connected components. Moreover, all of the components in your planned build combined draw almost as much power (at maximum load) as the maximum practical capacity of that Thermaltake-branded unit, even when none of the components are overclocked at all. That's way too close for comfort, IMHO.

And like other "600W" PSUs priced as low as that Thermaltake-branded unit, it is continuously rated at 600 watts - but at a rather unrealistically cold internal operating temperature of only 40ºC - which is the maximum specced internal operating temperature of that PSU. Unfortunately, PSUs realistically heat up inside to 50ºC or even 60ºC internally with these higher-performance multi-core components. It is at those elevated temperatures that the cheapie PSUs choke (*wraps hands around neck and throat*) themselves out (as it happens in the case of the aforementioned Thermaltake unit) - or worse, slowly poison (kill) some of the critical components with out-of-spec voltages and ripple even if they themselves don't croak, or (worst of all) explode (literally) into flames.

The pudding on this cake is its standing on the PSU quality tier list: It is rated on the next-to-worst tier, suitable only for very cheap PCs with only integrated on-CPU graphics. That's just barely above "garbage" or "landfill" quality - the tier that is potentially dangerous.

Why would you spend nearly $700 on the CPU and GPU but only $58 on the PSU? That's penny-wise and pound-foolish. As it stands, that $58 PSU is just suitable if you're only going to spend $150 on both the CPU and GPU combined (which means a quad-core or weaker CPU and only an integrated graphics processor rather than a discrete GPU). Even a decent 600W PSU costs more than $75, while real quality PSUs cost at least $100.

This planned build is the computing analogy to a car that had all of the high-performance racing-class components but equipped with only a three-speed automatic transmission from a 1980s sedan.
