OCIA.net checks out the I-Star 400W + 400W Redundant ATX PSU in their latest review.
One thing to note here is that both power supplies are fed from the same AC source. I-Star also has redundant power supplies that have two AC inputs so that you can hook one input up to a battery backup and one to a backup generator if you absolutely have to guarantee the system will not shut down due to power loss. For this project however, one AC input will work just fine as I am not running a corporate server off of this power supply.
