Answer 1

Googling the brand of BP. Reading. Looking for reviews (if any) on this brand or at least on any brand of this manufacturer.
Chinese non-name guano rarely squeezes out more than 60% of the declared power. Therefore:
- calculate the required power on the online calculator (thousands of them)
- take a PSU with a bronze certificate - it provides not only energy efficiency but also quality.
DO NOT SAVE ON PSU! You can be very sorry...

Answer 2

The power of the PSU is its most important technical characteristic, and therefore it is indicated not only on the glued label, but often this figure is included in the technical name of this PSU. But I do not advise you to believe this figure. The reason is marketing. Marketers need to show their PSU as more powerful, and they are interested in writing as large a number as possible on the label (although, of course, real, not from the bulldozer). The procedure for measuring this very power is also adjusted to this matter - a run for several minutes until it has time to overheat and burn out.
And you need this PSU to work not for minutes, but for months and years. Therefore, feel free to halve the power figure from the label - this will be its real long-term power.
So you correctly began to summarize the power consumption of components. When you find out the amount, double it at least, and buy for such power.
