Corsair TX650W PSU

3. Benchmarks

Testing PSUs is not something easy, we used the user side, meaning we gave to our system enough load either through extensive CPU and 3D usage via 3D Mark 06 v1.0.2 and burn-in tests with Sisoft Sandra 2007. Our test PC was:

  • AMD Athlon 64 X2 4600+ AM2
  • ASUS M2N32Pro WS
  • 2x Asus EN7900GS Top VGA cards
  • 2GB Crucial PC-8000
  • 1xWD 80JB SATA I
  • 1xSeagate 80GB SATAII

All PSU ratings were monitored with Everest Ultimate Edition v3.0. The following table lists the industry wide specifications for DC Output Voltage Regulation.

 

After running 3D Mark 06, the monitored outputs showed us how much stress the power supply has taken. A summary of the measured results can be found in the table bellow.

The results were very good. All ratings are within the standard range, while even at full load, the voltage only changes by 0.01~0.06V. The PSU can fully support a high performance system even with two energy demanding graphics cards installed.
