Barneyj41 Posted October 3, 2010 Share Posted October 3, 2010 So I just built my machine... The problem I came across is that the 8pin EPS/ATX connector for the Mobo is the same size as and takes up the spot on the PSU for the second PCI-E cable. So I can't use this PSU to do crossfire with 5850s. I don't understand why the EPS/ATX 8pin comes with a plug that has 12 (4 are not used) and takes up the spot on the PSU for the second PCI-E cable???? Any thoughts??? What did I do wrong?? The PSU finder says the 850 was the way to go for such a setup... Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 4, 2010 Corsair Employee Share Posted October 4, 2010 The PCIE modular cable would not fit in the EPS 8 pin connector on the PSU. The PSU has 2 modular ports for PCIE cables, these are 12 pin ports. The PCIE cables themselves will have a 12 pin connector on one side (which plugs into the PSU) and on the other side there will be 2 PCIE cables and connectors with the standard 6+2 pin PCIE which would plug into your graphics card(s). Both PCIE cables have 2 PCIE connectors so that gives you 4 available total. Link to comment Share on other sites More sharing options...
Barneyj41 Posted October 4, 2010 Author Share Posted October 4, 2010 Yeah I'm a moron... I didn't notice that there were two EPS/ATX cables that have different connectors on the psu side. One has an 8pin on the PSU side and the other has a 12pin as I said in my original post. I obviously used the wrong one. So when I add go crossfire, I have to swap that cable out. Thanks anyways...
