    Those TR2TT's are Thermaltake units. All but their ToughPower series aren't really units I run with today's systems. Those units have a paltry 18A single 12V rail, and that's nowhere near the required amount for today's high-end video cards. You realistically want 25A on the 12V or via combination of the 12V rails (when multiple rails are used). 30A minimum for Crossfire or SLI setups. The reason for this is that more and more components are running of the 12V. The two biggest power hogs, the CPU, and all PCI Express video cards, run off the 12V rails.

    Units I would recommend:
    -Antec TruePower TPII-550 (550W)
    -Enermax EG565P-VE/EG565P-AX
    -OCZ PowerStream 520/600
    -OCZ GameXtreme 600/700
    -Fortron (or FSP) BlueStorm/AX-500
    -Tagan TG-480-U22

    There's other good ones, but these are some of the more common good units.
    Other safe bets would be Seasonic or Silverstone 500W+ units.
