While the Thermaltake isn't very good, since the High Power isn't, either, so it makes sense to just continue using it rather than getting a second mediocre power supply. We keep a curated power supply list stickied in the Power Supplies forum and while everyone's going to disagree with something, it does a good job separating the good power supplies from the poor ones.
The may not be lying about Taiwanese capacitors as there's a large variance between companies and rating.
There are few brands that are recommendable across the board as it depends on the usage. For example, the Corsair VS, an entry-level power supply, is a perfectly serviceable power supply when you're talking rigs that don't use a lot of power, as in no overclocking and either integrated graphics or a discrete graphics card that doesn't use supplementary power (like most 1050 TIs). Your current power supply is of unimpressive quality, but it's also not likely dangerous for your current specs, as long as you're not overclocking; the GTX 1060 isn't particularly power-hungry. A better quality power supply is definitely recommended when talking about getting a high-end, recent Intel or AMD chip with eventually upgrading the GPU.
We go on a lot about power supplies and some people find it exhausting, but we see a lot of people coming here who see their components have shorter lives because they didn't spend $20 or $30 more on a power supply and now their $300 GPU is recycling center material. The more people we can save from that, the happier we are!
