Are any of you running linux? I'm on Linux Mint 16 Cinnamon and the AMD driver keeps screwing everything up. I tried installing fglrx, fglrx-updates (both native to mint) and the AMD Catalyst driver from their website but it screws up my system. The only driver that works is the native xserver-xorg-video-ati. Running anything else breaks xorg and I'm not able to boot. Any ideas?

But Im not gonna run Furmark on the PC -.-
And games tend not to stress GPUs like Furmark

How about, since you guys obviously got wattage meters. Boot up BF4, play for an hour and monitor your wattage with a camera or something.

I did google: 750W 7970 crossfire, 280x crossfire, 770 crossfire etc and seems the majority says its fine.
There is also a thread here on OCN where a guy asks about 750W and Crossfire and seems majority seem to say its fine.

280X mentioned on page 5 or something.

Hey guys! I have just completed my review for the XFX 280x Double D. let me know how you like it. Sorry in advance that I don't have full run of games but I do want to add that at my max OC I can play Crysis 3 at max settings give post processing and particle density.

http://www.overclock.net/t/1419675/is-a-quality-750w-psu-enough-for-7970-crossfire

280X mentioned on page 5 or something.

Then don't take my advice and get a 750w, that's fine if you think it's fine. At least go with the Gold rated though. You need to get what you think is best, all any of us can do is make suggestions based on our experience. My experience and from talking with others tells me I would not go less than 850w for if I wanted to push 2 x 7970's or 280x's. I have more than $1500 into my system, I will not compromise.

Dont PSUs have failsafe incase something goes wrong or its using too much juice, the PC shuts down?

If so - at First Notice - Get new PSU/Return PSU (if within returndays)

Most do however it depends on the quality of them and also how much do you want to rely on a fail safe that may not function correctly as all other electronics always carry that risk, I was running 2 GTX 460s pushing 1.087 with a gold rated 750w PSU (but key thing is that it is built with quality) I will need to check on the actual wattage that was being used by each card.

What DevilDog is saying is that why put that much money on the line as if a PSU fails or if a fail safe does not work correctly a surge of power can literally take out your entire system. You then would be out a grand. The thing about over head and PSUs is that if you work (just like any other component) it 100% at all times the life span would be greatly shortened. Not saying that it can't do it but why not spring for a littler more so that in the long run you do not A: have to buy another PSU and B: run the risk of pulling too much power and having the PSU fail.

As what has been stated it is your choice but is also a well advised suggestion. I have had a PSU kill a board, ram and chip so I am now more cautious.

Why would the system require 750W 24/7 during gaming?
It makes no sense at all.


Also 280X cards all seem to have this massive barrier blocking the Xfire connections meaning you have to buy additional bridges 23094meters long and bend them (possibly break em) in order to connect two cards.

You most likely will be ok with the 750w but as stated we are only suggesting what would be a great longer term solution, more or less future proof it.

No such thing as "future proof" in the world of computers.
