Power consumption

Hey guys, i need some help with my first computer build. I have selected the parts i will buy and use (listed bellow) but, well here is my story : i was planning to build a pc like this (ryzen 3 2200g,8gb ram, 1 ssd 120gb, 350w psu) and started ordering parts, the first was the ssd and the power supply, 350w for this kind of system is enough but later i started realizing that the vega 8 igpu would not be enough for gaming so the solution? this system: (ryzen 5 1600,8gb ram, radeon rx 570 8gb, 2 ssd 120,240gb). but one small problem: i have a 350w power supply and that's where i need help. will 350 watts be enough for my system? or will i need to buy a new one with more watts? (i don't plan to overclock but you never know...) oh and the games i want to play are demanding, such as PUBG, the witcher 3, gta etc.

first of all- ensure your ram is two sticks of 4GB, and at least 3000MHz. Running only one stick of RAM that is below 3000MHz is going to cause your performance to drop significantly because Ryzen does not perform well on slow memory

 

Also, the wattage of your power supply is not the only factor. efficiency, quality etc is important too. I wouldn't recommend going for 350W although you might be able to use it(again, depending on power supply quality) What power supply do you have?

 

You can visit the PSU Tier List to see what PSU's are bad and which are good. If it's not on the list it's probably really bad.

First of all, yeah i have 2x4gb of ram on my list but not 3000mhz, they are 2800mhz (g.skill ripjaws V)

And yeah my psu is not on the list but it has 80+ bronze certification. it is the Lc power lc420-12 v2.31

It had a lot of reviews and most of them were realy positive, thats why i got it.

I was planning to keep it for 1 year or so and then i would take a cooler master one or something, so i will change it anyway.

so what do you think?
