Yes, but these high end video cards usually require an extra power
connection. The PCI-E expansion chassis would need to offer the extra
power connection for all of the slots with a strong enough power
The high energy demands of video cards are the reason why high-end PCs
are coming with 1000W (or higher!) power supplies these days.
Keep in mind that the typical 115V wall outlet in the US is only
capable of supporting a max of 1500W, and a continuous power draw at
anything close to this level will heat the wires in the wall and waste
energy. A higher voltage outlet, and/or carefully-designed dedicated
circuit, may be required to safely/efficiently support the hardware.
