As my title says... I've spend some time and made some money to upgrade my PC. My PC currently has

RAM: x2 4GB (8GB Total) DDR3
CPU: AMD Phenom II 955
GPU: R9 270 2GB (without x)

PSU: Sirtec - High Power Element BRONZE 500W

What I want to upgrade to:

RAM: 2x 8GB (16GB Total) DDR4 3200 MHz
CPU: i7 8700k
New Motherboard: Asus Prime Z370-A
New cpu cooler (not important.)
New SSD

I will not OC my 8700k.

Later this year(maybe even next year i don't know), I'll upgrade to a 2080 and I'll change that PSU for sure to a more W PSU anyways but for currently I am wondering if that PSU is enough these upgrades or if I should upgrade it. (Sorry for my english.)

Thanks.

Reading through the product page, its mechanical PDF sheet and Spec sheet, and this "review" it is low end, dated PSU. Not necessarily crap.

It's using mid-level capacitors, sleeve bearing fan, low quality protection IC, and a group regulated design that leads to poor voltage regulation in modern computers, which is evident in that review.

The PSU's support just 400W on the 12V rail (20A max for CPU, 20A max for rest, 33A max overall) in conjuction with its mediocre quality, I recommend upgrading your power supply if you wish to accomplish your system upgrades.

Without overclocking, a high quality 550W power supply should certainly be enough for the i7 8700k + 2080.
How long of a PSU can your case fit? Any longer...

Where would you be buying from?

Thank you for your answer. Yes I'm from Romania. I will also buy a new case (NZXT S340 Elite) and I don't think I should be worried too much because of the dimensions. I thought of upgrading my PSU to Corsair - CXM 750W 80+ Bronze or EVGA SuperNOVA 650 G3 80+ Gold, can't decide yet. Are these PSU ok for my feature upgrades? i7 8700k, 2080?

Quality before wattage. The EVGA G3 is a better PSU than the CXM, despite 100W less.
Your system would be fine on a 550W too, such as the Corasir RM550x, Seasonic Prime 550, EVGA G3, be Quiet Straight Power 11.
