Starting with the 12V rail, the voltage there was off by 0.24V at most, which gives us 2% regulation. It varied between 12.16V (Test 2) and 11.76V (Test 7). That gives us a total variation of 0.4V, or 3.33%. The 5V rail varied between 5V on the dot (Test 7) and 4.94V (Test 2), which equates to 1.2% regulation. Although these results are tolerable, they are nothing spectacular. The 3.3V rail did much better, staying at 3.32V throughout most of the tests. While the regulation was somewhat tighter, the voltages did follow a similar pattern to those of the PSU I last reviewed (the Infinity 450W)

The efficiency was reasonable, peaking at around 85% during Test 3. The power factor was above 0.75 most of the time. While that’s a good result for a unit which only features Passive PFC, it’s still far lower than what could be achieved using Active PFC. I did attempt to overload this PSU to around 500W, and it exploded after a few minutes, so it clearly lacks OPP (Over Power Protection).

Another familiar pattern emerges with the ripple suppression. The 5VSB rail had the same overheating problem as the Infinity 450W. It’s ripple suppression was excellent until it warmed up, when it went through the roof. The other rails also displayed some similar wave forms to the Infinity, although the ripple on all rails was somewhat lower. As we will see on page four, this power supply is very similar internally to the infinity, which is why its performance was similar.
