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

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?:eek:
 
Im not sure, but if a high end cards uses most of the x16 speed then it would be nearly making SLI useless by cutting it in half. But im not sure, i can't find benchmark comparisons..

Some info here
 
Go for the 590. Trust me. Otherwise you'll buy a 590 3 months later because you couldn't help but wonder if there was a little performance you're missing out on.
 
I think I have saw where its only 1 to 3% even with 8800 GTXs between X8-X8 and X16-X16. If you already have a 570 board I would not buy a new board just for that. If your ungrading your board wait a week or 2 and check out some of the new AM2+ boards if you dont you will being buying a (Old) board right before the new ones come out. AM2+ boards will run AM2 processors just fine then you would have a better upgrade path for the Phenom later on.

Oh, wow, so i may only loose 1-3% of performance when SLIing x8 versus x16? if so, i probably won't even be able to tell the difference:D
