samarlian Posted August 10, 2010 Share Posted August 10, 2010 Running 2 X gtx480 sc edition in sli I have read many differnet problems or varients of rail distribution for the GTX480's and thought i would post here before i install my second gtx480 sc edition tommorow night I ran my 2 x GTX285 in sli in the below configuration will this be ok for my GTX480 in SLi Rail 12v1 CPU, MB, RAM GPU 1 PCIx GPU 2 PCIx Rail 12v2 HDDs x 2 SSD x 1 DVD X 1 9 X FANS & 1 WATER PUMP GPU 1 AUX GPU 2 AUX THX in advance Link to comment Share on other sites More sharing options...
Yellowbeard Posted August 11, 2010 Share Posted August 11, 2010 Make sure that both power connectors on each card are on the same rail. Don't pull from 2 different rails to 1 card. I'd suggest the MOBO + CPU and 1 GPU on 1 rail, the other GPU and everything else on the other rail if it will fit. If you have to put more stuff on the rail with the MOBO, put the small power draw stuff there. Link to comment Share on other sites More sharing options...

If you have to put more stuff on the rail with the MOBO, put the small power draw stuff there. How can i put some smaller stuff on the MOBO rail as there is only Mobo connector Cpu connector 2 x Blue PCI-E connector I am so confused with all the stuff flying around some are saying I suggested worst case senario (CPU OC 4.0GHz, GPU sucking 300W) Rail 1 CPU, MB, RAM = 300W GPU 1 PCIx = 75W GPU 2 PCIx = 75W -------------- 450W Rail 2 HDDs = 30W GPU 1 AUX = 225W GPU 2 AUX = 225W -------------- 480W others V2: 250W - 75W= 175W 250W - 75W= 175W 130/2 (CPU) = 65W 15W (Hard Drive) 15W (Hard Drive) 15W (Hard Drive) ~5 W (DVD) V1: 130/2(CPU) = 65W X58 Chipset= 25W 10W RAM 75W (PCIe) 75W (PCIe) So PLEASE help Do i put 12V1 CPU/MOBO/RAM GPU 1 X AUX GPU 1 PCIx GPU 2 PCIx 12V2 HDDs X3 GPU 1 AUX FANS & WATERPUMP & DVDRW OR 12V1 CPU/MOBO/RAM GPU 1 PCIx GPU 2 PCIx 12V2 HDDs X3 GPU 1 X AUX GPU 2 X AUX FANS & WATERPUMP & DVDRW After reading through the forums Ramguy suggests: The first card should be plugged into the 12v2 cables that are hardwired to the graphics card. If I hooked up the cards myself I would plug the second card into the 12v1 modular connectors which are closest to the fixed cable bundle. I thought I would post back that I have been running both cards on the 12V2 as suggested for over a week now and all has been working well. I am going to avoid too much of an overclock on the cards to be safe though, which is just as well since I am using air cooling and want to keep the temps manageable. So do i connect the SECOND card: on the 12V1 or 12V2. Sorry for all the confusion as i just want to get it right Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted August 11, 2010 Corsair Employee Share Posted August 11, 2010 You could really put the second card on either 12v1 or 12v2, you just want to make sure that both connectors that are plugged into the card are coming from the same rail.

HX1000 Rail Diagram How can i put some smaller stuff on the MOBO rail as there is only Mobo connector Cpu connector 2 x Blue PCI-E connector I mistated my last sentence in the quote. Since you can only put the MOBO and 1 GPU on rail 1, put everything else on rail #2 including the 2nd GPU. And no, you do not want the MOBO and both GPUs on the same rail. The cables are not suited for that anyway. This is the configuration you want. DO NOT split the GPU power across 2 rails. 12V1 CPU/MOBO/RAM GPU 1 GPU 1 12V2 HDDs X3 GPU 2 GPU 2 FANS & WATERPUMP & DVDRW Link to comment Share on other sites More sharing options...
samarlian Posted August 11, 2010 Author Share Posted August 11, 2010 Thx Ramguy and Yellowbeard done a little diagram of how it will be wired up so http://img80.imageshack.us/img80/252/hx1000wgtx480setup.jpg so does that config look correct Once again THX Link to comment Share on other sites More sharing options...
nitromullet Posted August 21, 2010 Share Posted August 21, 2010 Thx Ramguy and Yellowbeard done a little diagram of how it will be wired up so so does that config look correct Once again THX Looks correct as far as I can tell. Of course, the PSU is actually upside down (fan would be facing up) in the diagram... Something to bear in mind when plugging your cables in. I guess the key point to remember is that the 12v1 plugs are the ones next to the fixed cables, and the rest are 12v2. Link to comment Share on other sites More sharing options...

I essentially have the same exact loadout as Samarlian, and I want to be sure that I am wiring my HX1000W correctly as well. Link to comment Share on other sites More sharing options...

Looks like everything is hooked up to the ideal port on the PSU. Link to comment Share on other sites More sharing options...
