Hello,
I'm planning to run 3ea. PNY 9800GT EE graphics cards in a new computer I'm building. The only power specs PNY gives indicate that the minimum requirement is a 450W PCI Express-compliant system power supply with a combined 12V current rating of 24A or more. The problem is that I will be using 3 of these cards.
Unlike many graphics cards these do not have a supplementary power connector, so they will be drawing all of their power from the motherboard's PCIe power buses themselves. While I can obviously get a power supply that will deliver anything I want, I am concerned about the current handling capability of the motherboard PCIe buses themselves. I plan to use an Asus P6X58D motherboard but I cannot find any specifications on its power capabilities either. Any ideas/suggestions?
Thanks,
Ray
