Either total power drawn off the power supply. Or total power drawn off the PCI[whichever it is] bus power leads. Check if any of the add-on cards have extra power port (many video cards do). Card likely will work without extra power connected to it, but connecting extra power on the card may solve your problem. Next: borrow more powerful power supply and see if that resolves the issue. Or temporarily disconnect everything else (like all hard drives), and boot with all three cards off live CD, and see if that doesn't crash, then it is marginally insufficient power supply. I hope this helps.
