Quote from cyberjunkieCheck the price difference between the HX620 and the TX650. If it's tiny, take the HX620. Even if you don't care about modular, fewer cables and better airflow is a nice thing to have
It £22 more for the HX620. That and it has triple rails that give the same power as the TX's single, not sure if this is actually important or relevant though. One review I read said the triple rails on Corsairs all come from the same place so theres no benefit or some such rubbish.
