I think the issue is more connected to FSPs for having a lot of low-range PSUs.. not because it's a Chinese or an English brand

.
Based on my experience in the industry, it is not unusual to encounter extremely cheap PSUs that malfunction and emit smoke. However, this is also attributed to PC-selling companies prioritizing cost reduction to maximize profits. Sometimes, they would install low-quality PSUs in gaming rigs, taking advantage of the fact that the general population lacks knowledge beyond assessing the CPU/GPU.
Companies typically source from FSP or even OEM ones when opting for extremely cost-saving PSUs. This is because FSP offers a wide range of PSUs at very low prices and is readily available in bulk. Therefore, they often become the culprit in 'those' situations. Whether this can be considered an excuse for such scenarios happening is a matter of personal judgment, my opinion doesn't matter here.
While FSP has good PSUs like the one mentioned by
@KleoZy , they also have many that are low quality, which can lead to consumers losing faith in their products.
Ultimately, it's up to the brand to manage their reputation.
If I speak about gigabyte PSUs now, I already know how people will respond. It's the same thing.
