What is the best hardware for a home PC to build?

Question

Iron

Good day, I set out to update the hardware.
Now I have a Gigabyte G31 mother at home on socket 775, under it an Intel e5700 processor, 2x2GB Kingston 800, WD 500Gb Sata II.
Well, for today's realities, this is not enough and I want to assemble something on the 1150 socket. If I can still decide on a processor (initially it will be an Intel Pentium G3250 as a plug, and then i5-4590/4660), then I can’t decide on a chipset with my mother. Of course, it was cool to immediately grab the z97 or z170, but I don’t need so much, I wasn’t going to overclock the system relying on my hardware now. I want something medium gaming, sometimes with the ability to run OBS. At home there is a GTS 450 Cyclone card, I'm not going to update it yet.
What I have chosen for myself at the moment:

Zalman ZM500-LE 500W
Asus H81M-K (s1150, Intel H81, PCI-Ex16) # I doubt it
Intel Core i5-4590 3.3GHz/5GT/s/6MB # or ntel Core i5-4460 3.2GHz/5GT/s/ 6MB
Kingston HyperX Savage 120GB 2.5" SATAIII MLC
Kingston DDR3-1600 4096MB PC3-12800 HyperX FURY Black x2

Help with advice on mom, please ;-)
Thank you!

Answer 1

Look in the direction of this https://www.asus.com/Motherboards/H97PLUS/
PSU, I would also look at something else. And more Watts, suddenly in the future you decide to update the card after all? so take it just in case for 600.
The rest is all ok)
p.s. Do you have HDD besides SSD? 128 in total will be very small.

Answer 2

The processor can be simpler, and the memory, on the contrary, can be added up to 8. Personal opinion - as a rule, there is not enough memory (especially in games), and only then the processor and video.
The rest is ok.
