The overall performance is not competitive. With a longer hold-up time, better ripple suppression at 12V and 5V, and tighter load regulation and transient response on the minor rails, the UD1000GM PG5 would be closer to the competition.
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
Under normal operating temperatures, the average noise output is high.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The average efficiency is high.
Power Factor Rating
The following graphs show the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius and 115V/230V voltage input.
The APFC converter has decent performance.
