To test the PSU, we put our system under heavy CPU and 3D graphics load, using 3D Mark 06 v1.0.2. We then monitored the PSU voltage levels. Our test PC was as follows:
- ASUS M2N32Pro WS + AMD Athlon 64 X2 4600+ AM2
- Gainward 8800GTX
- 2x1GB Crucial PC2-8000
- 1xWD 80JB SATA I
- 1xSeagate 80GB SATAII
All PSU levels 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 levels shows us how much deviation each power rail suffers when put under load. The summary of the test results can be found in the following table:

The results are good. All ratings are within specifications, while even at full load, the voltage deviates by only 0.01~0.09V. Compared with other, similar rated PSUs, the Thermaltake RX600W had slightly greater deviations in the voltage rails, but nothing to worry about.
