Sakkura :
I wouldn't trust that power supply.
The combination of a locked CPU and an overclocking-enabled motherboard isn't optimal - you could either save some money on the board or get an overclocking-capable CPU instead.
Coffee Lake or Ryzen would probably be a better idea than buying old Kaby Lake hardware.
And finally, if you haven't bought the VR headset yet, you might want to consider an Oculus Rift or maybe a Windows mixed reality headset instead. The Vive is not worth its current price.
Thank you for your time
I've a few questions
I'm not gonna OC my GPU or CPU (Maybe Later i will do if i upgrade my CPU to K's & GPU to GTX 1080 OC)
& about the Motherboard its because of the Wifi & BT it has otherwise i was gonna go for Asus Strix Z270H.
If any other suggestion for Motherboard?About the CPU its just for now i mean after years gonna upgrade it to ofc the OC ones,If i get the GTX 1080 OC
Also about the RAM should i go for 16GB 2400Mhz or 3000/3200MHz?
About the Power supply as @RickRenzo have suggested about "EVGA SuperNova 550" i agreed,but i hardly find that in my Country(Iran-Tehran) if you could suggest other brand Good as EVGA would really Appreciated it
Once again Thank you for taking your time
