It has 2 x 8x PCI-E, and 1 x 4x PCI-E. Question is.. are these powered? Will they run a 7950 without additional power? The board is a super micro X7DB3. The Xeon's are cheap, and I am sure I only need 1, and the ram I have laying around as needed. Will this mine?
modern gpu's get their power from power supply... so you need a big 650+watt power supply for 2-3 cards
