I found two PSU reviews. http://www.overclockers.com/thermaltake-smart-series-530-power-supply-review/
"..The Thermaltake Smart 630 W proved to be a very good entry-level power supply, having excellent performance for this market segment, with efficiency between 80.2% and 85.2%, voltages closer to their nominal values than required (three percent regulation) most of the time, and low noise and ripple levels.

PSU looks OK to me. I use Seasonic, and would prefer that over this, but not a bad PSU.
Wattage is PLENTY for that configuration.
