4 GPU Titan Steup

	My 4-GPU Titan / Titan Black Setup is like this:

	PSU: www.newegg.com/Product/Product.aspx?Item=N82E16817182251

	Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813132262 (You have to switch the PCI-e port to at x8 speed and change boot parameter to include "pci=nomsi irqpoll" to get stable performance).
