Will Fractal Design Newton R2, 1000W run 2 x 6950 and 1 x 7950 24/7?

[headmaster200]

Hello I'm building one of my mining rigs, and have noticed that 1200W PSU:s costs way more than just a 1000W. So I'm planning to buy a Fractal Design Newton R2, 1000W 80+ instead of a 1200W as I've conventionally done.

Thus my question, I'm planning to run 1 x 7950 + 2 x 6970 ( wrote wrong in title ) on the system ( full load ) all time, everything else is practically the cheapest you can get. The motherboard is a model Asus P5K Premium.


Thank you in advance!

tbh i think 1000w should be fine adding up say if they are max 250w per graphics card then 750w for the three and the rest of you system is going to be about 200w so should be fine aslong as it is a 80plus psu but all three should be about 650-700w

The AMD drivers won't support multiple, different GPUs on one system. You can only have 3 x 6950s or 3 x 7950s. Mixing them will lead to system instability and ultimately failure.

sorry to post again but both the 6950 and the 7950 have a 200w power consumption which means 600w for the craphics cards so ye 1000 should be fine

I'm very sorry guys, I've got two 6970's not 6950. Have changed this info in the title.

Would this change anything, or is it still in the green?

Thank you all.

But that configuration will be impossible to run. The driver software won't allow it. It's not like Phys X where you can mix and match cards. All cards have to be exactly the same or you will risk system failure.

Are you sure? I've seen people run all kinds of different cards on their system?

 

[ngsilverwolf]

basicly you will need all three the same card pal and a 6970 is 250w so if you had three of them then its 750w palso should still be fine but dont cross gens...................

NVIDIA's Phys X drivers allow you to swap different cards for different performance levels, but I've never seen anything that allows you to do that with AMD cards. From what I gather and my own personal experience is that on AMD rigs all cards have to be the same in order to get the most out of Crossfire.

 

[ngsilverwolf]

the mod is correct even though he isnt answering the question but a 7950 and a 6950 are both 200w and 6970 is 250w all maxed but dont cross the cards keep them the same gen and card pal.

Ahh I see, no they will not be used in crossfire, but be linked by risers.
This setup is for mining https://en.bitcoin.it/wiki/Mining, so any use except that is not needed

Yes I see, that's really what I'm looking after. But will the cards be able to run 24/7 stable in this condition or will the PSU maybe be running too high resulting in breakdown later on?

 

[ngsilverwolf]

how much is that psu you are looking at ....

Depends on what power supply you get. You don't want to get a cheap one.

 

[ngsilverwolf]

the power supply is in the title MOD LOOOOOOK

I am planning on going for this one : http://www.fractal-design.com/?view=product&prod=29

Although I've previously used 1200W from Corsair which have run fine, but they cost 2x (!) the cost of the 1000W.

 

[ngsilverwolf]

i believe the psu you are looking at to be good for the job and dont see it failing but tbh i would go for http://www.overclockers.co.uk/showproduct.php?prodid=CA-025-SS&groupid=701&catid=123&subcat=2464

Thanks. Yes I would agree, but they do after all cost 2x the price of the one I'm looking at. The PSU costs are around 30% of the total costs so it makes a great impact.

 

[ngsilverwolf]

stick with the one you have looking at it now it should do the job you want
but me personaly would go for the one i linked just to make sure i got what i needed for sure plus you can always sell it again after

Check out this one then: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438010

This one is made by Super Flower, who is known for producing high quality units. That Fractal Design one is made by ATNG: http://www.tomshardware.com/reviews/power-supply-oem-manufacturer,2913-6.html

I would read some reviews before purchasing though.

 

[ngsilverwolf]

if you are a us man or somewhere where you can get this delivered http://www.newegg.com/Product/Product.aspx?Item=N82E16817153134 i believe that is good value for your money

 

[ngsilverwolf]

plus not amazingly known but has some brill reviews in http://www.newegg.com/Product/Product.aspx?Item=N82E16817152045 check it out for your self but i believe aslong as it is 1000w plus and has a 80plus badge plus good reviews then get it ...... after all your graphics cards at max going to take up 750 maybe even 700 and that is at the max

 

[headmaster200]

Thank you both for your suggestions, I've checked them up and unfortunately I live in Scandinavia so thus have no access to those nice prices 🙁

Have now checked up one guy who was also mining and he had the same PSU and ran 3 x 7970's so it should all be fine.

 

[ngsilverwolf]

all good pal i live in uk so cant get em either 🙁

 

[headmaster200]

Yea it's too bad to see those nice deals, so close but still so far away 😛
