Performance, Noise and Efficiency
Performance Rating
Compared to more expensive units, the VS650 doesn't stand a chance, of course. Unfortunately we didn't have any EVGA N1 units to compare it with, which have similar price tags.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).
Given its low efficiency, the overall noise output is at a decent level. The VS650 won't be quiet though, under high loads and increased operating temperatures.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30°C.
In comparison with more expensive 80 PLUS Bronze, ETA-S and ETA-A- units, it is only natural for the VS650 to finish the race last.
