First of all, thanks for the replies

that has one R9 295x2 in it, they are recommending that you use a PSU that has a 12V output capacity of at least 50A, which is 600W. This means that a good quality-made 650W PSU would be plenty if you had just one R9 295x2 in a computer because a good quality-made 650W PSU should have a 12V output capacity of 648W (54A).
so you are saying that My 750W Corsair will be ok to use in a first sime a single 295X2
Don't add amps like that by the way because you will always get unrealistically high results.
So, never add amps to amps in the way that you did it.
as i said, its theorical, but now, i had some informations about how the Power is calculated on the PSU .
This means that if Guru3D had added a 2nd R9 295x2 to their test system, then a good quality-made 1200W PSU would have been plenty.
So, I will say to you that a good quality-made 1200W PSU should be all you will need.
i'm interested by buying a AX1200i because i want to be equiped with Corsair brand, i have the ram, the Case, the watercool, the psu, then fans
but i'm not closed to buy another brand
Now, there's one question that needs to be answered by some experts, but in order for the answer to be given, we need to know what monitor you have. The question is this: would it really be worth your money to buy a 2nd R9 295x2 later on?
i play on a LG 23" HDMI monitor 1920x1080 ( LG 23MP55HQ ).
4K Gaming is not my priority now, but i consider play in 4k in few years, when 4K monitor will be cheaper .
I'm not an hardcore gamer and i hate the overkill in general, but if you look at the recommended setups in today's games, it's really complicated to get the game running good, even with the recommended hardware setup !
i mean 60FPS all the time MSAA 4X and Very High textures /graphics / visuals effects, i think the Radeon R9 295X2 is a good option to run many games without difficulties .

Hell, with the 390X coming out with ridiculous specs I would never buy 295X2 now, if I had the money of course. But if CF 295X2 is your plan I would NOT go lower than 1300W for sure, and that is if the cards are stock. If you're planning to OC and slide that power limit all the way up better get a 1600W. In any case, look for EVGA G2 1300W or higher, those are excellent quality and longest warranty of all.
i know there is the 390X coming in june or before , but if its to get 10FPS more... : I better get the Dual GPU board in hands
you know, i'm not a compulsive buyer who stays tuned into what graphics cards will come out, and then buy it .
no, I did not plan to overclock the R9 295x2 because i think the frequency (1020MHz) is ok to play GTA V in HD (1080P), or Just cause 3 , then Far cry 4 , and all the games they will come out in 2016/2017
so, now i know that having a Good PSU > 1200W is a thing to consider if i want to do CF-X.

Just so he knows to consider that.
i was searching for how many watts and Amps the FX-9590 CPU consume ? is it really 220W ?
i have smetimes errors in windows like "Kernel Power error" ... but my PSU is not used at 100% . i think its about 80% Usage .
in HW Monitor, i have 77W MAX when i am under unigine benchmark such as valley
or when i play GTA V , i can't belive the system is just pulling 75W from the PSU when playing or benchmarking...
I'm in this party, I'm assuming this is for an upgrade to a 4k setup. It's hard for anybody to know what they want right now really. On the bright side, in 4-6 years a 295x will be dirt cheap to add a little extra horsepower to the machine. On the other hand, we're talking a big chunk of change in power bills over the course of that many years and I'm sure the bandwidth on GDDR5 just isn't going to cut it in 2020, especially not at such a huge wattage.. But then what is the power consumption going to be like on a 390x and how much of an edge is it really going to have, it's all just up in the air for a few more months. I would vote to get the single 295x2 and then sell it and upgrade to a 490x, which I believe is what I'm going to do.
i'm Ok with you, and yes, i see as you see, no ones knows what he wants, i know i want quality built PC and high perfs !
in my old pc ( i mean old by before having what i have now ) with 8GB ram Radeon HD6950 and AMD Phenom II 955, i was able to play games, and do some video editing easily , but games were not playable in HD :/ . i had this setup for at least 4 years ! so assuming i'm interested by having the 295X2 in the next week , i want just to get a little extra perfs, i plan to buy another one later in 5 years,
then in 2020 i will see what is new, and what needs to be upgraded .
in some years, i think the R9 295x2 will cost a little lower, i had it for €699 . in other sites in france we can find them at €750 !!!
i want to take a single Card now , but also a Good PSU , in case of Wild CF-X with 2X 925X2 ... or if i upgrade with another GFX card .

I'm figuring around 1150W for it at 80% TDP & Load counting all his drives and the cpu cooler + assuming a few fans. I would figure the 1200W would be good but could be insufficient for an overclock and high stress levels depending on the machines use. You're the PSU wizard though these are just my thoughts
i do not want to overclock, definityvely, its not necessary on this AMD FX 9590 !
i use my computer to play games first and to edit footages taken from my gopro . sometimes i do After effects work, i do application developpement too.
I worry about the heat this kind of setup is going to create, CPU temps are definitely going to be jumping up quite a bit from the heat those GPUs throw off, especially if you set up the GPU rads as intake to favor lower GPU temperatures, I'm assuming the rads are going to go in the dual 120mm front fans on that case. It's definitely something to consider, you're talking about a MONSTER amount of power in that puppy
yes i planned to put the fan on the rear of the case, inside, but leave the two fans in the front bring fresh air . if i have a CF-X i will change the placing of rads, and stick them to the front of the case where there is the 120MM places.
the heat is not a problem for me, its good in winter, but i have conditioned air in my room for the summer
also, DDR3 1033? Are you able to run those at atleast 1600? I would think to upgrade to a higher speed kit over jumping to 16GB, I'm wondering what speed you have your current kit set to.
yes, I did a mistake, its in facts 1600 MHz , 2x4GB , if i CF-X i will jump to 16GB .Edited by al3x360 - 4/25/15 at 7:08pm
