Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v7.2 (Windows/Linux)

Hello

Its a 1300w edga gold power supply enough to dual mining with 6x of msi r9 390x?

Not really, you will need to undervolt a lot and maybe underclock, and run low -dcri. Even then you are pushing limits of it, consider dual PSUs. Their total TDP is 1650w. Someone on this forum does it, and it is very unstable.

Hello,

And 1300w for 4x msi r9 390x its possible?

4 would probably work, would still want to undervolt just to lessen load a bit.

how much i undervolt?

As low as possible without it crashing...

I would get a killawatt meter ($20), and test wattage at wall, then factor in PSU efficiency, and try to keep PSU under 80% capacity.
