OCIA.net takes a look at the Etasis ET-850 850w Power Supply in their latest review.

The ET-850 is certified to be SLI Ready by Nvidia, and even features four PCI-Express power leads for graphics cards. It is rated for over 80% efficiency with four independent +12V outputs, and has eight Serial ATA power connectors. With plenty of power and plenty of connections, it sounds like it's ready to take on anything available on the shelf from quad-core CPUs to SLI graphics cards with as many Serial ATA drives as you can fit in most cases.
