i have a core i7 950 build thats running all stock housed in a antec 902
theres only one hard drive
6 120mm fans
wont be overclocking
i know the requirements ask for a 700 watt psu with 48amps but my psu is 3 amp shy on the 12v but i have 50 watts more then the card asks for


anyone think i will run into issues with this set up with a gtx590?

I'm going to guess that you will be okay, particularly since the rest of your system seems to go light on the power usage.

What brand and model of 750watt supply do you have?

Unfortunately "750 watts" doesn't really set much of a standard. A Cooler Max 750watt supply would be lucky if it would boot your system with ON-Board graphics... while a Corsair HX750 will arc weld the frame on your car....

So, what do you have ?

Ah, no such luck Ultra, Professional .... etc won't help this power supply....

Even IF they meet there own specs this is a 45A on 12volts or a 540 watt supply.......... not even close to a true 750watt supply.....

decided im just gonna try and get a better 750 watt psu perhaps something with 52+ amps on the 12v,i know ultra as a brand is crap and i,ve had a 750 watt thermaltake tr rx crap out on me with a single gtx580 so i know my chances with the ultra are cutting it close with a gt590,thanks everyone for your replys,think its best not to cheap out on a psu,requirements

Well while your working your way up from crap supplies to REAL supplies (dude, teh GTX 590 is a BEAST your not going to drive it with some second rate supply...)

P = V * I (electrical engineering formula...)

750 watts = 12 volts * 62.5 Amps

BTW a Proper supply for this graphics card would be the Corsair HX850. That would be 70A on the single 12 volt rail. All day long....

I love the Corsair 850HX supplies because they remain dead silent to almost 600watts...

yeah crossfire does suck (at least for anything other than 6900s in crossfire) I abandoned my 6870s bc of the terrible stuttering which is a product of low minimum fps, for now im happy with a single oc'ed 570 until I can sli down the road with a stronger cpu then the one I have...

OP:

the PSU should work but Ultra is a skeptical manufacturer at best and Iv'e seen many threads of people having issues with them, so if you can afford a gtx 590 then you can shell out the 100 bucks or so to get a proper psu... you can try the ultra but you might regret it (instantly or down the road)

yeah i have always used single nvidia cards all the way from my first purchase a 7900gt to my 8800gts512mb to the gtx280 to the gtx295 to a gtx580,all evga with zero issues,i buy this system from a friend for $800,bam my first pain in the ass set up,i should stick with what i know:p  i know the low min frame issue when i get on a server for the first 5 seconds,the card just bogs down to like 12 fps,if theres a spawn killer im down for it sucks lol

yeah well i bought this system from a friend for $800 the first appearence with the make of the psu hidden gave me the first impression it was a corsair or thermaltake,all the cables are sleeved it looked very sharp till i pulled it out of my 902 and flipped it and saw the brand,i know i was disappointed but i figured perhaps anyone had any good experience with them LOL yeah i already figured im gonna go with a 1,000 watt psu,call it overkill but people said that about a 750 watt psu back in 2008 im sure too:p  i always figured a 750watt would be enough,i had a thermaltake 750 watt toughpower power my 7900gt,my 8800gts,and my gtx280 and my gtx295 crazy that nvidias later dual gpu offering asks for that huge of a psu,i guess effficiency is out the window now with nvidia LOL:p  but i guess you gotta pay to play

dont worry about me overclocking this if i get it:p  not gonna do what the other dummies did on the reviews and overclock a gpu that has the max wattage that a video card could pull thru 2x 8 pins and a pci express slot,i read somewhere that this card is at the limit of what a single card could ever push,whats next?a 14 inch card with 4x8 pin?

sounds good but really for anything less than a 6990 or or gtx 590 a good 650w is all you need imo, high end crossfire and sli are of course going to require that 750-1000w psu

dont buy a gtx590yet. you may face serious issue.

1- TechPowerUp, 267.71 burned
2- Sweclockers.com 267.52 burned
3- Itfiles.ro driver unkown burned

6- Micutzu, Lab501, 267.71 no voltage incrase / burned
7- Tweaktown 267.71 burned
8- Pclab.pl 267.71 burned

buy a 6990 which is the faster card especially at high resolutions. you wont
regret it

Even the quadfire scaling is better than nvidia... nuf said



read the post carefully before you get all out of whack, I was referring to a specific case where my crossfired 6870s (not 6900 series) did suck and offered terrible minimum fps, even though the averages were high the sporadic microstutter that was a product of the minimum fps that occurs when adding a second 6870 drove me insane and I have no idea why someone would spend over 400 on gpus for crappy, laggy, overall terrible performance... I was fed up and bc I play at 1080p went with a single PNY GTX 570 (it overclocked to 580 levels and saved almost $200) over the HD 6970 and I am very pleased, the 6970 is also a great card, but I'd rather have less quality frames then suffer from the minimum fps plight of the 6870s in crossfire. I was not in any way talking about the 6950/70 which seems to not suffer from the same problem...

My question is, what are the minimum fps loss with a 6970 or 6950 crossfire setup, over a single card, I have heard that sli seems to keep a higher minimum than crossfire in general but im wandering about the 6900 series, So really does anyone have any info on fps minimums with the 6970 or 6950 in crossfire?

well I'm glad there are at least a couple people on here that reinforce my point, but I really feel like there is a reason that you pay a premium price for an Nvidia product, and even if the 6900s scale better than the 5 series Id still take a 5 series sli setup because of their better minimums. Higher minimum fps will also come a lot more into play when the 6970s or sli setup are not able to play the game at 60+ fps and the graphics begin to flirt with that 35-50 fps mark... of course by that time everyone will probably be running AMD 8 series or nvidia 7 series or something, lol

but then again the 6970s in crossfire do seem to be a better choice for multi monitors/ high res gaming so its a tough call but I'd like to see how the 6950/70 fairs regarding minimum fps when in crossfire mode....?

All the people i have heard complain about AMD/ATI dont have the patience or knowledge to find a solution to their problem. Also, as to the amd crossfire "stuttering" problem, that is easily fixed by disabling vsync or enabling tripple buffering with vsync.

^ no, low minimum fps is a product of 6870 crossfire by nature. I personally had this setup, dont you think that I would have already tried all that? it has nothing to do with vsync and triple buffering, this problem was consistent with it on or off, I think it is different for the 6900 series but for my setup, the 6870s did not work as advertised and now I am much more happy with a single gpu, low minimum fps is a deal breaker and if the minimums fps on dual 6870 is much less than with a single 6870 then that is not worth it imo, has nothing to do with not being able to fix a problem and there are many competent pc users that feel the same. Does anyone have any benchmarks of minimum fps on crossfire 6970s im really curious to see if it suffers from the same plight my 6870s did or not....

Another reason that I Went to a single card was because I felt liek my p2 955 @ 4.0ghz did not have enough overhead to properly control 2 gpus, so in my case it made even more sense to switch to a single powerful gpu.

If you have owned this setup or something similar then you would know what im talking about, if you have not owned a similar crossfire setup then you might not understand how shitty the overall expirience was with the 6870s in particular, by no means am I saying that this is true for the 6900 series cards but the is why i wanna know about mimum fps...

please some numbers on minimum fps of 6970 crossfire would be nice how many minimum fps does it lose from a single card to a dual card?

the simple fix?lol everyone getting a 6990 and dealing with a card thats louder then a 426 hemi warming up from 200 yards:p  naw i kid idk i think bc2 has alot of issues with crossfire and sli,i cant say for sure but considering a few of my friends have the same complaints with the game

oh yeah and i saw a gs700 corsair today at best buy for $115 i jumped on it the 12v rail ratings look good at 56amps,675 watts dedicated to the 12v,from the reviews looks like none of their systems pulled 600 watts on full load,so i should say im safe,i couldnt help but notice for some reason today i heard a compacitor in the ultra make a noise when i turned it on and off,glad i ditched it eitherway

for anyone who wonders why anyone would pay a premium on a card like a gtx590,probaly doesnt wanna bother with the two cards,one possibly failing maybe?twice the heat twice the noise,finding that right driver i know my 5770 crossfire i went with 11.2 10.5 i then tried one year old 10.4 after reading a forum i had very few issues after that driver still had a occasional lock up but it was rare,i was able to game for 4 hours straight last night no issues period,i woul gladly pay the premium for a dual gpu as ive owned one,and i had zero issues with it,besides gta4 and sli support,but that would be game developers at fault

Rocketfish hardware stuff you have to hit and miss with because they simply re-brand items . For example, in my workstation computer I have a Rocketfish 900W PSU but I actually did my research and it's a Huntkey 900W PSU which has a very solid build with the 80+ Silver and good build quality. So don't shoot down Rocketfish right off the bat.

i saw one at best buy today and i was gonna buy it but im not to familiar with the brand i saw the gs700 corsair psu with 56amps on the 12v,since ive used corsair products ranging from fans to ssds with no problems,i use what i trust,maybe in a tight spot ill experiment with a new brand but i like staying in my comfort zone,i know friends who bash asus products cause they had bad experiences with them back in 2006 LOL its stupid crazy cause asus makes the best motherboards now

doesnt seem to be any problems there. Maybe it was your MB or CPU?


yeah I definatley think that my CPU was holding me back a bit even though it seems like it should be ample but likely just not powerful enough to manage crossfiring 6870s I suppose but I do think that there is some notable performance loss in other games beyond what those benchmarks indicate but no doubt my cpu was likely a limiting factor, at the end of the day I'm happy with a single card for now, when I upgrade my motherboard and cpu to something more high end I might try sli or crossfire again...

signature had it as if you had plurals when i saw 6990,s it kinda gave the impression you had two:p  i heard about those monitors how are they im comparison to lets say a 22 inch 60hz monitor that does the same resolution?is it one of those 3d monitors? but wow i couldnt see what game on gods green earth could use dual 6990s,man ramp those fans up to 100% gonna sound like a jet ready for take off:p  i usually keep my computer on 24/7 and its in the same room me and my gf sleep so why i didnt opt for the 6990,to many reviews about the noise,but if its in a seperate room and i had noise cancelation headphones hell yeah i would prefer one over the 590 in a heartbeat:p  assuming the drivers are stable after my crossfire ordeal not sure if im ready to rock another amd product but if my lucky frys doesnt carry the 590 and they only have the 6990,then the choice is obvious :p

whats crazy bro is that i had just last week a amd athlon x2 555 with a gts250 i couldnt play bc2 on my 1600x1200 19 inch crt monitor unless i dropped the settings to medium and enabled dx9 ,but this set up even with a single amd 5770 can play it at high with dx at auto on a 1920x1080 this is with bc2 pretty crazy huh?i was able to unlock a third core using a gigabyte mobo and my frames jumped thru the roof,but still had dog slow loading times and a crappy min frame,i know the 5770 isnt that much different from a gts250,but yeah i know in games like bc2,the cpu makes a world of difference
