Under clocking-Afterburner and PSU for 2 graphics card

[Sparsh Bhatli]

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...

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

not even for mining ?

especially not for mining, gaming has down periods why temperatures can reduce, mining doesn't, it's very very stressful on components.

Someone said that I can here:

anyways I won't risk it might buy new power supply

that's a good supply, i'm not sure what a 470 and 570 would draw.

The GPU's look to draw 300W between them in total, so 550W should do it.

thank you
I will underclock them to use less power like 100w
