Conclusion

I should confess my impressions about Topower products are not all positive. The company seems to have a good potential and shows the ability to develop and manufacture interesting products, but too many of them have this or that defect. It’s just funny how those defects may show up – I can remind you of the clumsy rubber knobs on the connectors and of the stiff screened cables, for example.

Among the discussed products the Topower Silent Green TOP-600SG seems the most interesting. Although it is not exactly quiet, its parameters are going to satisfy most users. The Tagan TG500-U35 combines good parameters with an original, fascinating packaging.

The other models are not so interesting, unfortunately. The P7 series is obviously outdated now, and the PSUs from it didn’t meet the output voltage ripple requirements in my tests. The P8 series seems exciting on paper, but turns to be not so pretty in reality. The 700W PSU couldn’t work under full load while the 800W model would be good if it were not for the strange operation of its PFC (but I should acknowledge that the other parameters of this PSU meet all the requirements).
