And then you still have to buy the boards, cables and use a 240v outlet.

Much simpler to buy the other PSU's that come with everything you need and use 110/120v. In case you were not fully understanding, you get two PSU's in that kit with all the boards and cables pre-assembled for $119.00.

If you want to go in another direction, that's fine. But I think I was giving you the best option.
