Crossfire PSU and Mobo Tags: New Build Crossfire Systems Last response: June 18, 2010 4:32 PM in Systems Share chiknbane June 18, 2010 4:11:47 PM I'm building a new pc in a couple of days and getting a HD 5830 with the intent of adding a second later. Will this PSU be good enough for crossfire http://www.ebuyer.com/product/152506 if i get a couple of http://www.ebuyer.com/product/124029 because it needs 2 6-pin each. Will there be enough connectors and do you need to put 2 4-pins or just one in the adapter? What would be a good/cheap AM3 mobo that will support crossfire? Do you need 2 x16 bandwidth slots? Whats the performance difference if you use a x8 or x4 slot? Will be with: Phenom II x4 965 4Gb 1333MHz DDR3 Antec 200 case with extra 120mm fan 2x500Gb HDDs in Raid 0 More about : crossfire psu mobo Transmaniacon June 18, 2010 4:18:30 PM http://www.ebuyer.com/product/135514 get that instead Yea you need 2 4-pins to make the 6-pin, you will have plenty of spare ones for this. This motherboard would work well, http://www.ebuyer.com/product/196392 though its not true crossfire with only 16x and 8x, though the performance decrease is pretty minor. Stepping up to this http://www.ebuyer.com/product/218919 would give you the full crossfire, as well as some more updated features. I would stick with that 790 board. I would drop down to the Phenom II X4 955, because the 965 is only factory overclocked, by one multiplier, this is something you can do yourself with one click, for $40 less... batuchka June 18, 2010 4:32:12 PM 1. You would want at least 8/8 on PCIex16 gen 2.0 for CF 2. Why not try to hit a HD 5850 and stick to single GPU solutions? Can't find your answer ? Ask !
