Am I understanding correctly that only 1000 w psu has more then 2 pci e connectors for triple sli? I mainly just want to run a 2 8800 gts 320 in sli + 1 6800 gt card for physicx processing when games that support it come out. I was hoping to go the ocz gamextreme 700 w but found it only has two pci e connectors. I also want to attempt my first oc on an intel 920. Is there anyway I can do this with anything less then a 1000 w psu , or is there a psu thats less then 1000 that has more then 2 pci e connectors?
 
forget about doing that with those graphics cards... the performance is going to be worthless, seriously.

about the power supplies..... my Tagan BZ800 modular one has 4 of them, infact even my corsair tx750 watt one has 4 too.. a lot of power supplys under 1000w do.
 
The OCZ GameXtreme line is based on the FSP Epsilon platform, which has out of ATX specification DC ripple on the 12v lines under heavy load which can kill your hardware. Avoid it. Stick to Corsair, PC Power & Cooling, Silverstone, Seasonic, Antec (Earthwatts only) and Thermaltake (Toughpower only). The BFG ES-800 is also a really great supply.

8800 GTS 320 SLI doesn't make sense; don't purchase another card unless you own two already. The limited amount of video memory prevents the cards from excelling at any resolution about around 1680x1050 in pretty much all modern titles, and below that resolution a single card will be plenty fast. You would be far far better off selling your 8800 GTS 320MB (or both, if you already own them) and purchasing a single 8800 GT 512MB, or if possible, better yet a GTX 280. They're down in to the $200 range now, and extremely powerful for the money. A Radeon 4870 1GB would also be worth considering.

The 6800 GT has no stream processors and is not CUDA compatible; it cannot perform PhysX calculations. Assuming you meant 8600 GT, it is too slow to be an effective PhysX card. The absolute slowest card that is any good for PhysX is the 9600 GT (far different core than the 8600) / 8800 GT. You might also consider keeping one of your 8800 GTS 320MBs for PhysX.

You might want to look here first.

I haven't had the time to fully spec out an i7 CPU yet, but, it would appear that the i7 has somewnat different needs (voltage) then we have seen for a while. This might also explain many of the questions of those who purchased some of the newer bigger PSUs not understanding the voltage spread between the three basic rails.

I'll do some more research but a quick look at Intel's specs looks like a rethink of PSUs might be in order.
 
Thanks for the input guys, I originally rma'd two 7900 gt's and got two 8800 gts 320mb cards in return. No doubt, there is better stuff out there. Thats why I was thinking about upgrading my processor from a fx-60 to i7-920 to push those two cardsin sli faster and oc- but after hearing you guys, I'm halfway wondering if its not just better to keep my fx-60 with 470w ocz powerstream and just ditch the two 8800 gts- for the new 55nm gtx 285. I can do either or , but not both right now. What would actually yield the most performance?

About the psu- I always thought 1000 w was overkill- but I'm glad to know there are psu's less then 1000 out there with more then two pci-e connectors.

6800 gt will go in the crap drawer since it cant do physx, and I'll keep at least one of the 8800 gts if I go with videocard upgrade path.
 
system A - Core i7 920 with 2 8800 gts 320
or
system B- Amd fx-60 with 1 gtx 280

putting price aside- which choice would yield more performance in game?

The second, because the 8800 GTS 320MB is very low end by today's standards. Were we talking about a 9800GTX or Radeon 4850 with an i7 vs. a GTX 280 and a FX-60 it would probably be something of a draw unless you're talking very high resolutions,
 
Yah , I'm really hesitant to drop that coin for i7 right now-
it would mean buying a new mb, processor , ram and maybe a new psu. unless 470 powerstream could hang with just a standard sli and and i7 920- sometimes its tough being a cheap bastard :) . Thanks for the responses.
 
"Avoid it. Stick to Corsair, PC Power & Cooling, Silverstone, Seasonic, Antec (Earthwatts only) and Thermaltake (Toughpower only). The BFG ES-800 is also a really great supply."


That's incorrect, the Antec signature series are superb.

They're not that great. The Earthwatts series are built by Seasonic, and have superior DC output quality when compared with the Signature series... and Signature series is overpriced anyway. There are far superior options for less.

There's no way in hell your current PSU could take an i7 quad and a SLI setup. No. Way.

I would not try with anything less than a 750 watt, and your current 470 watt probably has a true maximum output of about 400-425 watts due to its age (PSUs de-rate slowly over time -- I'm assuming your supply is roughly 3-4 years old).
 
Heard good things about the signature series, but I would also have to agree with silent-circuit that they are way overpriced.
