I have searched a lot,and they say its possible with a good 1000W psu to handle two 7990,but,it will compromise my Overclocking in the processor?ddr4 sets consume more energy(all the rewiews were in DDR3)?I have only one 7990,should i just buy another one when i exchange my psu?This one is a dam good psu I wanna try.Waiting for help!

Thanks for all the help I always can get from the Tom's Hardware community!

R9 295X2 quadfire needs more than 1.4KW

7990 TDP is 325 i think or something so 650 for the cards alone calculate your CPU TDP in it might as well use a PSU calculator to see how much your system will eat im sure that the HX1000I might handle it as the PSU is known to go even above it's limits and not shutdown until 100~ watts later lol but that will kill it fast ha ha
