Best psu for dual psu extreme gaming setup

hi,
i am setting up a extreme gaming rig....i dont know that much about psu's..i think using 2 psu's will be more power efficient.....i saw some videos on youtube where people run one psu only for the mbo and stuff..and another one only for the gpu's..i think that would be a better setup than a really high wattage psu like the lepa g-1600w....so here is my rig hardware---
i7 3960x oc'd to 5.0 ghz
asus rampage 4 extreme
xfx radeon 7970 dd blaack edition running in 4 way crossfirex,core oc'd to 1265 mhz,memory oc'd to 1500 mhz
gskill 64gb black edition

so which psu's should i buy for a dual psu setup with these extreme hardware??

i searched bit and found these...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

i didnt put the silverstone strider 1200w psu link here cuz on the gpu support list,it says that the psu can run only 3x 7970's and am gonna use one psu solely for the gpu's so silverstone is a deal breaker..it might be able to run the gpu's in quadfire as it has all the connectors,but i dont wanna risk it....

am gonna be using this to daisy chain the psu's///
http://www.frozencpu.com/products/13815/ele-933/Add2PSU...

i am taking the easy way by buying the this one cuz i dont know much about the wire cutting and relay and stuff..lol

am probably gonna be using the same psu's as its gonna provide more stability or something..

plz help

thnx in advance

Damn this is gonna turn out to be one awesome setup.. (never tried this before so don't know much but... )

Just quickly looked at the given 4 PSU.. Looking at the Pictures Choose XFX looks lot cooler.. haha
i will reply back again after i check those PSU properly, when i get back gotta go somewhere first..

why have all gpu's off one psu. Everything else will take maybe 250W max, so unless you are going really unbalanced, i.e. a 300W psu and a 1200W psu then 2 x 800 would probably be perfectly fine as a single good 800 could cope with crossfire.

Your biggest concern with this, and i'm guessing you are inexperienced, is cooling that setup without going deaf, those 4 cards will need a lot of air, and will be choked by the small gaps between them. You will hit some unique and interesting problems on that build I am sure.

oops! Sorry, 1000w is not enough i thought you were talking about to crossfire in only 2 way but i've seen you have mention for 4 way crossfire so definitely need about more than 1000w.

Yeah checked it out, Every one of them is a damn good PSU's (people have their preference like looks, brand name etc) but all of them should easily be able to handle all your setup.

I am stuck at
1) ENERMAX MAXREVO Series EMR1350EWT 1350W
2) XFX ProSeries P1-1250-BEFX 1250W
3) COOLER MASTER Silent Pro Hybrid RS-D00-SPHA-D3 (for some reason i like this one no too sure why as haven't used it before..)

There is something else i am thinking 2x 1250W (XFX lowest) would be 2500W.. I have seen any setups ever needing that much power. Are you sure you really want to use 2X these, that would be waste money/electricity if you go with something moderate it will save some money as well as "planet" lol.. (climate change and all that crap)

Anyway just wanted to point out as mentioned by someone else before as well what is your thought on getting 2 a bit lower wattage PSU or just getting that 1500-1600W PSU should still be fine i don't see a problem ever occurring and this would also mean more free space inside the case helping you with the cooling a bit.. (and if a 0.05% chance (random guess) problem somehow does occur lower than you still have the option to add in another small PSU)


Personally If i had to go with one of the above 5 PSU x 2 setup than i Would go with "XFX ProSeries P1-1250-BEFX 1250W ".. Just due to the fact it looks a bit cooler than other.. sry when looking at this high level PSU's, I don't see a problem in any of them. Just small pluses and minuses which wouldn't normally matter anyway.

anyway let us know what you decide and post some damn good videos/pic after you complete the Setup. send me the links so i can check them out...

one of those psu's will be at about 20% the way he is setup right now, which is stupid.

20% of Each PSU will be 1000W if he decided to have both PSU.. Considering he is planning to OC the processor to 5.0GHZ
than 4 x 7970. When Gaming at Max 7970 Can take up to 300W Considering he is using all 4 he wont ever reach max (probably) but still around 250 x4 = 1000w
The 4x GPU will alone take in around 1000W if he runs them at MAX... so he should have min 1350-1400 W.
And max he will probably use ever will be around 1550-1650 if he has other things in CPU and also running very high.

though you are right he would be fine with one of those 1400-1600 PSU without problem as he would never use 1000W on 4x GPU as he wont be able to puss them to limit. processors/rams/speed will bottleneck this long before.. (might be wrong hey but it is still cool 4x 7970)

All the work above is my Mathematically genius brains work. (I self awarded myself this title..)

2 x 1250 watt units = 2500 watts

would you not be better off getting two graphics card, say two GTX 670 they will max out any game and reach around 80+ FPS, having 4 Graphics cards cause alot more problems than they are worth. unless you want to bench mark because the only resaon i can see is bragging rights.

are you going to be water cooling the cards then? because it makes no difference how big your case is if you are running 4 cards as the wont be enough space between them for the air to get to them.

Of course i came to help, i explained that the are no real benefits to using 4 graphics cards and that there are simpler cheaper alternatives, that wont cause problems, unless you are going to be benchmarking or just want bragging rights the isn't much point in spending this amount of money, if you do want to benchmark or you do want bragging rights that's fine but you would be better of getting 4 GTX 680's as they are superior to the 7970's. and as for the points thing that made me laugh, i couldn't give a rats ass about my points, im here to seek advice and give advice and express my opinion and nothing more.

let me clear some stuff about your biased comparison with the radeon 7970 and gtx 680

1.the gtx 680 can be quad sli'd but nvidia only approves of 3 way sli...+there are no guides for the 3d surround with 4 way sli gtx 680

2.the gtx 680 only supports 3 monitors+1 extended....and 3d vision is not availabe for potrait setup

3.gtx 680 has limited oc capabilities

4.i don't like nvidia

see..here are the 4 reasons why i didn't buy gtx 680's

ok..here goes why i bought the 7970's

1.they are 4 way crossfirex certified

2.each of them can run 6 monitos(currently 4 as there are no certified mst hubs and no monitors that have both display port in and display port out+you can play games on four of em..not like nvidia 3 monitor+1 extended:p )

3.7970 has extreme oc capabilities

4.i love amd

so 7970 is the best choice for me..and about the 2 way sli with cheap gpu part......i think you haven't read my post properly...i listed i7 3960x,asus r4e,64gb g.skill black edition ram in hardware......i think you can understand by now that moneey is no option and i want the best of everything

so what is the result??you got PWNED...LOL
