do you guys think 3 x 290 non x + 2 x 270 (x) + system enough for single 1300+ w gold psu maybe add a entry psu for system?
I am just to build a similar rig for mining with same gpu but different psu
1. 3 x 290 non x + 270 (x) + system = 1300w or maybe with a entry psu for system ( 1300w for all gpu) + system and etc for 400w
2. same but with old psu setup ( 1000 + 750w) ( 2x 290 non x + system) on 1000w and 270x and 290nonx on 750w
both system mostly mining x11 coin
