In Turkey, I can mostly find Thermaltake, FSP, Corsair, Cooler Master, Gigabyte, Sharkoon and Zalman. I just wanted to know if 650W going to be enough for that CPU and GPU, even if I am not going to get two of them. I just don't want to be in trouble in future, I mean after 3-4 years of usage, I don't want to change my PSU once more only because it doesn't provide enough power. The one that I mentioned was the only one who offers a good W with a good price but it is a B Tier. The PSU that I am using right now is Thermaltake Smart 650W and I want to change it since people saying that its nto safe to use it.
Looks like I can get this one

That is also out of stock but I added that into my wishlist too. Thanks for it.
