Hi, I have a gaming pc but don't play games on it anymore so I decide to mine altcoins with it... So my question is will my PSU able to run 2 graphics card ?

I have Amd Rx470 4gb and just got rx570 4gb and is still in the box...(Got it for 350$ and was last pc)

Here's my specs:
PSU: corsair 550w
Ram: 8gb
Processor: i7-4790
HDD: 2tb

I am not gaming anymore just mining and regular pc use watching movies and youtube stuff...
So is this PSU suitable for mining with these two cards?


I have BIOS mod on rx470  and I am not going to mod my new rx570

I am new at overclocking and under clocking so here's my afterburner settings
