What's wrong with your Ultra X-Connect, that's one of the PSUs out right now in my opinion...
And please keep in mind that the thermaltake has a 24 pin BTX connector, and you will need an appropriate ATX 20 pin adapter if you plan on using that PSU with an ATX motherboard.
To the person who suggested to stay away from Thermaltake, can you please provide some sources which you are basing your claims from? I'm not arguing with you, but I have only heard good things about Thermaltake and I am interested in hearing others who think otherwise.
