SLI question about the EVGA X58 Classified

717 Views 11 Replies 4 Participants Last post by  06si
I was wondering if the X58 Classified can run 2 cards in SLI in the first and third PCI-E slots? Assuming you had the correct SLI bridge of course. See pic below.

you can run sli in any of the 16x or 8x, once you get to 4x you might start to see a bottleneck, I don;t think even many if any cards can get bottlenecked in a 8x slot, maybe a gtx 295 or a 5970 but I'd need to see proof

lol noooo they are all 16x when used in a pair on the E760, so you can use the first and fourth for SLI or what ever, OP yes thats the standard SLI setup anyway.

sorry, I was just reading the print below the slots, it says 1st slot-16x, 2nd slot-8x, 3rd slot- 16x, and 4th slot- 8x.

its funky, it goes like.. GPU1 and GPUx = 16x16, X being one of the 3rd PCIe slots. but when you mix it up with say 3 GPUs its now 16x8x8. or even physx will drop it down to 16x8x8

On a side note, what PSU would it take to run this and 3x of the GTX 285 Classifieds? Would it require a second PSU?
I'd say atleast 1000w would be needed maybe more like 1100w, maybe 1200 if you plan on running an i7 at some point

I was thinking what specific PSU that would have 9x 6pin PCI-E connectors?

I use corsair HX1000w 1000watt psu. That's with 2 9800gtx+, 1 ssd, 2 2tb hdd, two radiators(rx360 and rx120), pump, two waterblocks, and 5 delta fans without any trouble. Let's see what other people might suggest

http://www.newegg.com/Product/Produc...82E16817256054 although it only has 4 8pin and 4 6pin. Additionally, you can use the 6pin to molex adapter that comes with the gpus and power it using molex connectors from the psu

here's another one http://www.newegg.com/Product/Produc...82E16817256038 has 6 6pin and 3 8pin connector
