That is a couple of years old now, but still just as relevant today as when it was written.

Figure out how much wattage each component will consume and add 30 percent to that. If you're planning to overclock, double it.

The advertised wattage is actually one of the least important factors.

The amperage on the 12V rail is most important
2nd would be efficency
And 3rd would be the wattage

Seasonic and Corsair are pretty much default good brands. Antec and Fortron/FSP generally pretty good too.

What you need depends on what components are in the PC and we have no idea about that.

Too many people buy on the basis of watts, subject to their budget, and end up with a a mediocre unit, when a less powerful but high quality PSU would be much preferable.

There are only a few PSU manufacturers---but there are dozens of brands. Which means that many of the brands contract with the manufacturer to build a PSU subject to the brand's specifications and intended price point. The brands often choose to use cheapo internal components and then sell the thing based on an inflated wattage rating. Why not----people eat it up. If 350 is good, then surely 650 is better, right? Right?
