SLI or not?

Can someone help me find a good deal on a cheap SLI PSU? I don't know much in this area, and i was wondering if there are any PSUs that aren't SLI certified, but have enough connectors for two graphic cards. if not please reccomend a cheap SLI PSU. (you can look @ my sig to judge how much wattage i need) Thanks.

A bit off topic, but why do you need 8800GT sli'ed?

B/c it beats a single GTX or Ultra... Not what I would do but, I wouldn't try to mess with his what he wants.





Cheap? How Cheap? I would spend a good amount on a PSU, and for SLI the same, that's two Gfx cards you have riding on that power supply and if it malfunctions it could take your card/s with it....

I'm not necessarily going to use the 8800gt in my build although i was planning to... but if i get a less powerful one, i want to be able to SLI in the future if need be. And how many watts do you think i need?

Also, to answer my other question, how rare is it for a non SLI certified PSU to have enough connectors to power two video cards? (the number of connectors the PSU has is the bottleneck, right?)

No it's the amps and watts.... Try something like this...

I see you have the nForce 570, you do know that it will only allow SLI at x8/x8, right? The 590 will do x16/x16 in SLI mode.



If it weren't the 8800GT i wouldn't say there would be a difference in SLI on a 570, but i havn't seen benchmark SLI comparisons on the 570/590



I would say your going to have to dish out $130+ for a SLI PSU to handle those cards



Edit: i always recommed that Corsair 520w, OCZ GameXStream 600w, Corsair 620w, OCZ GameXStream 700w



Those are all in the $100-140 price range i think.

I wouldn't really be inclined to use the HX520 or GameXStream 600W for SLI'd 8800s, even though the GTs draw less power than any of the previous cards. Better off to spend a few more dollars on something a little more powerful.

Corsair's HX620 or TX650 would be at the top of my list. The Antec Trio 650W will do the job at under $100 as well.

So i need a 590 north bridge to SLI in PCIe x16?

Correct!



but their should still be a performance increase on the 570

How big of an increase? will it be worth it to SLI? and how big of a difference in performance is there between SLIed x16's and x8's?
