If you really want to know the how, then you need to be able to look at and understand proper PSU reviews. And if you want to do that effectively (i.e being able to examine and compare each part of the review, not just the final score or even the conclusion which can sometimes be vague when it comes to details you should know if you want to compare), then you need to understand what there is when it comes to PSUs.

If one of us were to walk through a review explaining everything, it'd be long and time-consuming, so actually showing you fully how to choose a PSU the best isn't something most are going to be willing to do. Normally I'd be willing to do something like that, but I won't have the time until at least late next week.

If being able to effectively look at reviews to compare and choose PSUs is something you are willing to be able do, then I suggest checking out the relevant PSU sections (PSUs, and Power supply related, respectively) here:

The first thread has articles that will cover most the technical stuff. This should give most of the technical background you need to know. The second thread mostly has various bits of information that are more relevant to system builders, and can play a role when choosing a PSU (don't forget the PSU platform database by OrionFOTL, who is on this site right now as I type this). The first thread also has 10 links for PSU reviews that you can use.

Beyond this, it helps to spend some time somewhere like the jonnyguru.com forums. You can also try searching for things there with google using site:jonnyguru.com/forums/ It also helps to read a bunch of reviews and collect tidbits of useful information into something a text document.

double your max estimated wattage

This is a good way to end up spending a bit of unnecessary money or choosing a generally inferior PSU unless you plan on really power-hungry upgrades. PCPP's wattage estimations already overestimate a bit when it comes to how much power your components as a whole require.

But, when you actually do go to choose a PSU:

  1. Decide on a wattage and decide on your budget. Like I said above, PCPP's estimations are generally more than you would actually use (although overclocking can change that situation). A good quality, modern 450W PSU is fine for the vast majority of mainstream, single CPU, single GPU systems, although such PSUs may be limiting when it comes to cables. PCPP will automatically filter properly when it comes to cables (and physical length) when you have compatibility filter on. Don't bother with 80+ ratings unless electricity is somehow expensive enough for you to worry about efficiency.

  2. After you've narrowed down to some promising choices, look at reviews. This is the hard part, as you could probably tell from above. Use Orion's platform database to fill in the gaps for specific models in a series that might not have reviews. Ones based on the same platform in the same series are almost always pretty much the same in the end. Compare based on what you know.

  3. Decide.
