  1. It really doesn't matter as they're both good choices. I'd get OCZ because it takes less time to read. That's how pointless it is to decide between the two.
  2. I'd go with a Seasonic or FSP as they actually produce their own parts and build the PSU themselves... neither TT or OCZ do.
  3. If I were you I would take corsair's HX850 . It is one of the best series ever made and it's manufacturer is Channel Well which is for years the best psu manufacturer. The only downside is that the HX850 is 80 silver while the others you suggested is 80 gold. Still the difference is small, so i would prefer HX850.
    The final choice is yours. :)

    Btw Thermaltake and Corsair give 7 years warranty. OCZ gives 5 years.

  6. You can get objective PSU test data on power and performance from, and Tom's so you know which PSUs are quality units as all Corsair, Antec, Rosewill, etc. branded PSUs are not the most reliable and you can't tell which are good PSUs without objective, scientific testing and internal component inspection.
  7. This OCX ZX series 1000 gets a 9.5 Performance rating

    This OCX Z series gets an 8.5

    This Toughpower Grand gets a 9.0

    Seasonic X-650 (10.0)

    Antec HCP-850 (9.0)
