Cx750 is 2x overkill. I'd rather you see if evga 500b is there than pay for that amount of wattage. You can't open er clock your cpu or memory, you are likely getting a 150W gpu. Truth be told you don't need 500W.
Can you the website of retail store I put link above, and find the PSU, then tell me. Cause when I searched that site, I can't find good PSU in that price range, that are semi modular or full modular that are at least 80 Plus Bronze or above.

Like ED said, I would recommend changing the PSU to a lower watt but higher quality unit. It is a foundational component and you don't want to cheap on it. The Corsair CX series is serviceable but you can do better for approximately the same amount of money since you don't need nearly 750 watts.
Another recommendation I have is changing the 1TB spinner hard drive for a smaller SSD, at least if you don't need a lot of storage space. Truth be told, most people don't come close to using 1 TB of storage space. There are exceptions of course, particularly those who archive a lot of pictures and music. But an SSD will give your computer a performance shot in the arm in everyday computing like nothing else. The computer will boot and load programs in a fraction of the time it would when using a spinner hard drive. Look at changing that spinner hard drive for a 240-256gb SSD.
Finally, you have no video card listed. Will the games you list run acceptably on the processor's built-in GPU? I'm not a gamer so maybe some other forum members can chime in here.
I chose HDD, cause my budget is $600 lower for total price including tax.
I live in USA, so, sales tax is addition to price.
Also the component that I didn't listed, I already have/ going to use what I already have.
Also, if you seen what I'm going to use this PC for (All the Sims 3 and Sims 4) which needs lots of storage to store, I need that 1TB space.
Also, please check the above post for the retail store website for PSU and tell me what to recommend, cause that website, is where I always buy and I have to buy what they are actually selling.
