ok i has HD 7970 in crossfire OC to Ghz 1050mhz core 1500 on memory, my CPU is OC to 4.3ghz i5 2500k, i has Corsair Gold rated 850W PSU
now from what i can tell TDP of 290x is 300w each, and crossfire HD 7970 stock voltage is 250w each
500w vs 600w i did the power supply calculator the 290x were not in listeing so i went with HD 7990 +HD7970 to replicate close to same power draw with 4HDDs 6fans+2 140mm and 1 SSD with 4 sticks of DDR3 ram it said 700w total TDP . i think power draw of 7990 is 350w idk.
What do you guys think?
