is 500W enough for R5 3600 + rx 580

[Kokkinoskoufitsa]

I am looking to buy a new psu. This is my system:

cpu: amd ryzen 5 3600

gpu: msi radeon rx 580 8gb oc

mobo: gigabyte aorus pro b450 

ram: 2x8gb corsair vengence 3000mhz

storage: 1x ssd 250gb | 1x hdd 500gb 7200rpm 

fans: 3x140mm | 1x120mm

So after searching for a while in the available shops I figured out the best options I got are Seasonic CORE GC 650 and Seasonic CORE GM 500. They are both 80 gold plus,and I've read some good reviews, but 500 version is semi-modular and 650 version is full-wired. Also the 650 costs about 5 more EUR. 

So the question is, are 500 watts going to be enough for my system? Or should I get 650 which feels like is going to be an overkill? if there was a 550 or 600 version I would have definatelly gone for that one... 

I am also thinking about adding 1 or 2 led strips in the feature. Dont know if that contributes at all...

Thanks

A ryzen 5 3600 consumes less than 100 watts, and the 580 is around 200 watts (give or take)

 

You will have a lot of room to upgrade with a 500 watt power supply.

Hi guys and thanks for the answers. I eventually went for the 500W option. as @Fasauceome said, i do have enough room for upgrade. Also, I saw the effiency curve of the seasonic core series and it reaches maximum efficiency of 90% at around 40-50% load, so 200-250W for the 500W psu. I believe that is what my pc will be drawing most of the time(idle-netfix-youtube) and it hits the 90% efficiency right in the spot. On the other hand for 650 unit, the 200-250W range == 30-40% load, at which range I would get an efficiecy of below 90%. 

Also the 500W unit being semi-modular and cheaper...

The 650 unit would give me better efficiency under load(gaming etc.), but its fine, I dont game that much.

Thanks for the answers anyway
