Hello, I started gathering some parts to start my first build! I already bought a case, cpu and a motherboard which I will list below. Now the only thing that I am stuck on is buying a PSU with the wattage I need. I used the cooler masters website to calculate it and came up with around 460 Watts, but I don’t know if I can trust that. Here is a list of the parts I have and expect to buy:

I have:

Case:
Enermax Saberay RGB Mid Tower Gaming Case with Tempered Glass Panel, 3x 120mm T.B. RGB Fans and 1x 140mm Fan Pre- installed

Motherboard:
ASUS ROG STRIX B350F GAMING

CPU:
AMD RYZEN 7 1800X (Might be overclocking)

SSD:
Samsung Evo 850 500Gb (want to buy one more with 256Gb to boot the OS on)

Monitor:
Alienware AW251HF with Free-sync

Keyboard:
Logitech g910 orion spectrum

Mouse:
Logitech - G502 Proteus Spectrum

Headset:
Logitech - G430 Over-the-Ear Gaming Headset

Speakers: have a 5 piece set but I do not know the name since I’m at work :)



What I want:

GPU:
GTX 1080 or Rx vega 56 ( waiting on the new nvidia 11 series cards first, then comparing prices)

Ram:
looking for cheap 2x8Gb

Cooler:
Still deciding between air cooling and water cooling


If you have any considerations on changes/parts or tips please feel free to let me know :)

Good charts from Lutfij.

On ram, be very careful. Ryzen is picky about ram.
Stick with the ram QVL list for your motherboard.
Or, check with a ram vendor support app and pick a compatible kit for your motherboard.
Good looking case, it has 175mm headroom for an air cooler.
The very best would be a noctua NH-D15s, but other tower types with at least a 120mm fan will do.

My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
Past that, A AIO radiator complicates creating a positive pressure filtered cooling setup which can keep your parts clean.
And... I have read too many tales of woe when a liquid cooler leaks.
Google for AIO leaks to see what can happen.
While unlikely, leaks do happen.

I would support an AIO cooler primarily in a space restricted case.
If one puts looks over function, that is a personal thing; not for me though.
-----------------------end of rant--------------------------

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.

i learned the hard way, so i always go by the 650w+ rule for builds. thats just me. if i was going for a mid level cpu on a basic board using onboard graphics and sound , maybe not

No, unless your ryzen is an apu with included graphics.
My post on build process was oriented around a intel build which I favor.
I will have to edit it for more generality.
