Corsair VX550 PSU
3. Benchmarks
We tested the PSU under real-life conditions, meaning we put our PC system under heavy load with extensive CPU 3D loading from 3D Mark 06 v1.0.2, as well as burn-in tests with Sisoft Sandra 2007. Our test PC setup is as follows:
- 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 the power supply had deviated under load. A summary of the measured results is given below:

The results were very good. All readings are within range, and even at full load, the voltage only changes by 0.01~0.07V. The system can fully support a high performance PC with two VGA cards installed.
