First off, you don't need to bother about going with the 250 or 300W versions of the HDPlex as they are no longer made. Unless you plan to purchase used, the 400W is your only option now.As far as which power solution to use, you have three options. If you want to run the system without limits, you can purchase a Dell 330W brick and have significant overhead to run your system comfortably. Your second option is to run your hardware setup off of a single 210W brick, but undervolted/underclocked in order to stay within the 210W rating. Your third option would be to try using the Mini Box load sharing device Larry @ HDPlex recommended (http://www.mini-box.com/Y-PWR-Hot-Swap-Load-Sharing-Controller). The device is rated at 10A per channel with 20A output total. Hypothetically this means you can use 190W from each AC-DC brick to push out up to 380W which means you're doing quite well with two. The adapter can accept 5V - 30V inputs which means the use of a 19V brick is fine.
