AXP / Xion SuperNova 600W |

Performance
I miss several important certifications here like UL, TÜV and VDE. While this does not mean that the PSU is bad it may be important for companies where certain policies are in place regarding equipment use.

Tested on: AMD Athlon64 FX-62 @ 2800 MHz, ABIT AT8, 2x 512 MB DDR400, WD Raptor 36 GB, Radeon X1900 XTX + Radeon X1900 XTX Crossfire
Voltage stability is good, the 3.3V line flucuates a bit more than normal, but still stays inside the limits set forth by the ATX specification.
The ripple voltage was measured on the 12V line at idle. With an amplitude of 17mV it's sufficiently stable but nothing out of the ordinary. Overall the voltages seem to be ok, especially if you consider the total wattage of "only" 600W.

Standard deviation is a statistical term, which tells how far away from the average the measurements are. In other words it's the average of the average.
A large standard deviation indicates that the data points are far from the average and a small standard deviation indicates that they are close within the average.
While we have seen a lot of very efficient PSUs in recent tests, the AXP SuperNova 600W can not score here. Around 74% is not that bad, but in times where 80+ is advertised on almost every PSU and people getting more and more concerned with PSU efficiency this could become deal breaker for some "green" people.
