I'm building a new rig of 4x SLI (more would be better), however I'm having difficulties deciding on a motherboard, a PSU and case,
With total requirements for wattage its upto about 1400w and I can only see 1200w PSUs for sale so I think i'll need to put in another.
Does anyone have experience of any cases that will support the 4xGPUs and 2x PSUs?

I was thinking Asus IV Rampage as I don't really need more than 1 CPU just pure GPU processing.

So far this is the spec
1x or 2x Corsair Professional Series Gold AX1200 Power supply
4x GTX590
1x i7 2600k
4x 120gb SSD RAID 0 (Not Picked the exact one type yet yet)
1x 1tb 7200 RPM Hard Drive
RAM Undecided but around 12gb mark

Thanks In advance
 
Sorry my mistake 590s are dual GPUs it will have to be 580s.

This is also a serious post its not something that I've ever really wanted or needed but this rig will fit a very specific purpose hence my mistake around the 590s. It is not for gaming it is for other processes in which i need pure GPU power as well as the SSD's to read and write quickly too.
 
I was hoping for air cooling but I doubt that that will provide enough cooling for the the system. So I guess water cooling, to be perfectly honest thats more of a case of cross that bridge when i come to it regarding water cooling.

You should be able to use 8 GPUs, I know you can with 4x 6990s under Linux.

Not together then? or at a reduced performance? (i think you can get crossfire working without a bridge, but im sure the drivers for windows support 4 gpu's maximum) as there is only one set of fingers per card for the crossfire connector, the same is true for the GTX590, it only has a single SLi connector.

I thought SLI/Xfire bridge is only needed if you're gaming? For pure GPU processing, the cards can manage on their own without the bridges, I might be wrong though. I dunno about Nvidia but with multiple AMD cards for bitcoin mining, Xfire bridge isn't needed.

Without going watercooling, you can try something like this.

(Custom made case and few PCI risers)
 
Yes I looked into the workstation cards but to be honest there isn't a requirement for stability for this project. Just pure grunt so the use of teslas would be a waste of money when i can just use consumer grade stuff and save the money and buy something quicker or more to make it quicker

ironic post there?

My guess is rendering that can be done by the GPU, but exact software/purpose is beyond me.

:p

I'd guess that if he wants SLI its gonna be a gaming rig. If its folding or some other rendering purpose I'm pretty sure you don't need to SLI the cards to get the most out of them.
