rcarkk Posted November 22, 2010 Share Posted November 22, 2010 My PC with two GTX 470s in SLI is configured this way. I have respected the HX1000 diagram that Power Guy posted here. Is this correct? MB + OC Quad core CPU + RAM on 12V Rail 1 = 180W GFX Card 1 PCI-E MB Slot on 12V Rail 1 = 75W GFX Card 2 PCI-E MB Slot on 12V Rail 1 = 75W DVDs + HDDs + Fans on 12V Rail 2 = 50W GFX Card 1 with the two fixed PCI-E Cables from 12V Rail 2 = 75+75W GFX Card 2 with two modular PCI-E Cables from 12V Rail 2 = 75+75W Total on the 12V Rail 1 = 330 Watt Total on the 12V Rail 2 = 350 Watt Some people recomend to put one of the cards PCI-E cables on the 12V Rail 1, but from my math, the Rail will be overloaded. Is this correct? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 22, 2010 Corsair Employees Share Posted November 22, 2010 There is no way to overload the rails on this PSU. Just make sure you do not have 12v1 and 12v2 connections hooked up to the same device and you should be fine. You have about 500 watts on each rail. 12v1 is meant to power your motherboard, CPU and a single graphics card. 12v2 is meant to power up to 2 more graphics cards along with your accessories.
