Does an Corsair HX1000i can handle a stock 7990's crossfire in my system?

[Mandre96]

heres the built:
Asus X99 PRO
I7 5820k @4.5GHz Water cooled(Thermaltake Liquid Cooling System Big water 860)
16gbDDR4 G.skill 1600 Mhz
Quadfire 2xHD 7990
HX1000i 1000w 80 plus plantium 96% or more efficiency.
raid 0 2x250gb Kingston SSD NOW
Case Chaser a71 LCS
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!

1 7990 uses around 300 - 350w depending on your model so yes u can run 2 cards but overclocking could be a problem since it doesnt leave u much space. If you really wanna overclock i would swap the psu

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

Overcloking the gpus is out of question with only a 1000W, but it will be dangerous to do the 4.5 overclock in the 5820k?Thanks
