New Gaming Pc

So what do you guys think about this budget gaming setup. I am going for a red and black setup, but anyways these are my parts.
-DIYPC Solo-T1-R Black USB 3.0 ATX Mid Tower Gaming Computer Case with 2 x Red Fans
-EVGA - 400W Power Supply
-MSI B350 PC MATE AM4 AMD B350
-AMD Ryzen 3 1300x with Wraith Stealth Cooler
-GIGABYTE GeForce GTX 1050 DirectX 12
-Crucial Technology Ballistix Sport LT 8GB (2x 4GB) 288-Pin UDIMM DDR4 2400 MT/S (PC4-19200) Desktop Memory Module Kit, Unbuffered, 512Meg x 64, CL16, NON-ECC, 1.2V, White

Is this a good setup becuase I want to run games like gta 5, pubg on low, bo2/3, gmod, games like these. I am trying to save money so do you think going back to the 1200, or what about cheaper ram or good power supply. Also would all of these parts work together, and make a good pc and do you think 400w is enough for all that. I am going to ask my family for the cpu or gpu for christmas so which one should I ask for? Do I have to buy windows ten too or w7 or does it come with it. Anyways thank you guys in advance becuase I know that is a lot of questions.

U should change the psu to a seasonic s12 520 or corsair cxm 450 or cx 450 2017.

An if you can, get a 2800/3000mhz ram.

If you are playing e sports, a 1050 is OK. Else, get a 1050ti min.
