I want to know How many GPU can be used with one power supply 1000?
I have one R9 390X and one R9 380 now...
Can i use two R9 290X too? totally 4 GPU (R9 390x - R9 380-R9 290X -R9 290x) with one power 1000?
thanks
No
Not if you are mining coins. The 290x are power hungry.
Also you should be in alt coin.
I assume you are mining eth coins.
