Corsair 1200i unable to handle the pc?

[Derpherpderp]

lately, i bought a sound card for my pc, asus xonar phoebus solo and after 3 days, pc started experiencing some weird problems.
my pc components:
gpus : radeon 7990 and 7970 cfd
cpu: i7 4770k
psu: corsair 1200i
mb : maximus vi extreme
ssd: 128gb sandisk
hdd: about a TB seagate
no waterblocks or something

The problem was that either my ssd or my hdd didnt work. When I connect to the mb only the ssd, it works fine, when i connect the hdd alone, it works fine too.
but when i have both connected, in the beginning, both work fine but after some minutes, the hdd gets automatically disconnected. Also have to say that this happens if no gpu is overclocked with extra power. If even one has +20% power enabled, the pc doesnt even turn on.
Im not so experienced in hardware problem solving etc but the meaning i could give to all this is that my psu is cant afford all this power? psss
case doesnt support an extra one and im not gonna give other 400 euros for a better one...
what do u propose?

The corsair is more than enough power for your specs.

I dont know if it plays an importand role, but i have many periherals too. gaming keyboard, gaming mouse, headset etc
if the psu is ok with these specs, what would seem to be the problem?

They use very little power , 1200w is plenty.

Could be a board issue .

 

[Derpherpderp]

that would be even worse...
im pretty disappointed with the maximus vi extrme rog design... if the sata gets broken by just pressing the cable on it, im done with rog...
is there any possibility of needing format or a new hard disk?

 

[Dark Lord of Tech]

You could try it but , the 2 storage drives should stay connected and running together.

If you format only leave the SSD attached while installing windows.

Install the HDD after your up and running.

I agree with everybody that you have way more than enough power. But, if you want to make sure, isn't the 1200i the one that supports CorsairLink? You should be able to see exactly what the real-time power output is.

And finally, motherboard is extremelly bad designed, actually my second gpu's fun touches the sound card chip i have to pull the card upside in some way. aparta from that, it had about 8 sata 3.0 gates and everyone doesnt work now, cuz its "sensitive". if we put the cable in it, we break it...
and the 1200w is not enough...
when i have everything on, the gpus' fans work but there is black screen, but when i disconnect the sound card, the pc works.
nope, the hdd is not connected...
im really mad with all this sh*t

lol this corsair link is the worst software i have ever seen...
doesnt even show the current power provided to the systems
