Performance

Performance of the Tagan TG480-U01 PSU

One of the only meaningful tests that can be performed on a computer PSU is the fluctuation of core voltages provided by the unit. When the computer is "stressed" during benchmarking, the power loads on each component will differ from idle, and due to the laws of electronics cause a slight fluctuation in the voltage drop provided.

A high accuracy multimeter was connected to the various power connectors coming from the PSU. The Min / Max values were taken over a period of 10 minutes from initial bootup, idle for 2 minutes, and then the remaining time running a "burn in" test application. This should stress the power supply to a maximum and enable min/max readings to be taken from each individual power source.

All of the results recorded comply with the ATX12V specification, and are well within the recommended limits. None of the voltages slip below the required voltages, and are always slightly above - which is a good sign under high loads.

Tagan state that the maximum current for the PSU is as follows:

• +3.3V at 28A
• +5V at 48A
• +12V at 28A
• -12V at 1A
• -5V at 0.8A

These values resemble those of similar PSU's in the same high-end class, and should be enough to power any consumer system to a high degree of reliability.

Conclusion

Final Conclusion on the Tagan TG480-U01

The Tagan TG480-U01 is one of the latest generation consumer PSU's, and has several features that you would expect on a high-end model (such as Active PFC, multitude of connectors and stable voltage lines). Conversely, several items that you would not expect are included too, such as an array of extra cables/ties to neatly install the unit.

The overall build quality of the unit was very pleasing to see, as I initially had concerns when the price tag was significantly lower than other high-end PSU's. This is one of the best constructed PSU's available, and the 3 year warranty is very reassuring. A lot of thought has been put into the design, with twisted power cables, extra grounding protection and a membrane covered power switch.

With near silent performance, high build quality and high performance, this is a PSU which would ideally suit enthusiasts and high-end users. The power supply should last more than a couple of upgrades of the main system, and will be able to cope with the new power standards being introduced soon.
