I have Ryzen 5 1600 & EVGA GTX 1070 FTW. How big PSU should I get? I already have 620W 80+ Bronze PSU and I was wondering that is it enough? I'm not gonna do much overclocking.
 
Solution
Even a quality 450W PSU would be fine with your system with overclocking. You're good! All that natters is the PSU quality and if it can handle the load, and the only way to know whether it'l handle the load is by knowing the model anyway.

Basically, and like anything else, you should a) never install something less than the manufacturer says you should, b) Allow for overclocking if planning to do so, c) select a quality product and d) make sure it has the appropriate PCI-E cables ... adapters are never a good idea.

a) https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1070/

Maximum GPU Temperature (in C)
150 W = Graphics Card Power (W)
500 W = Recommended System Power (W)4
8-Pin = Supplementary Power Connectors

b) http://www.guru3d.com/articles_pages/evga_geforce_gtx_1070_sc_superclocked_gaming_review,8.html

Here is Guru3D's power supply recommendation:

GeForce GTX 1070 - On your average system the card requires you to have a 450 Watts power supply unit.
GeForce GTX 1070 SLI - On your average system the cards require you to have a 650 Watts power supply unit.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.

c) The Seasonic S12 and M12 designs are solid products.

d) If the cables match what the card wants (2 x 8 pin), you fine .. the PSU has 4 x 6+2-pin PCIE so you fine
