[EVGA SuperNOVA 850 G2]

Hi,
I'm worried about my EVGA SuperNOVA 850 G2

I have 3 GPUs:

• Asus Strix GTX 1070
• Sapphire Radeon RX470 Nitro+
• Sapphire Radeon RX480 Nitro

Will 850W be ok if I add a MSI Radeon RX580 to the rig?
What could happen if I test it?

Thank you.

Hi,
I'm trying to overclock my sapphire nitro radeon rx 480 8gb to achieve greater hashrate than the current 23.5 I got.
I followed the steps I did to overclock my nitro+ 470 8gb (used Uber-Mix timings) but I now found 2 groups of timinig straps on Polaris bios editor.



I copied the timings to the 1st group, didn't change anything. The same if I modified the 2nd group. If I modified both, Ubuntu won't even start X.

Can somebody help me to overclock this card?

Thank you
