On the ASUS website, there's a PSU calculator, but it doesn't work. It
always recommends 0 watts when I select all the options describing my
cpu, number of drives, etc.

A couple of the Asus pages are like that - they work in IE6 but
not in Firefox.
In any case, you're not missing anything. The Asus web page, rounds
to the nearest 50 watts, so tells you the power is 50W, 100W, 150W,
200W etc. And when it decides to switch from one value to the next,
does not inspire my confidence.
For selecting a power supply, what you also want to know, is total
amperes on heavily loaded rails, like the 12V rail.
There is only one online power calculator that I liked, and the
web site has been shut for several years. An ideal power calculator
web site, should offer a spreadsheet output display, showing what
all component values for the power are. This allows verification
of assumptions.

I've been using this one as of late. It's Mozilla/Firefox
friendly and let's you model different scenarios.

That one looks pretty nice. For my new build it said 297W so I got a
Corsair 620W. No problems at all.
The one I finally chose was based mostly on this review:

Would you want to buy less than a 750 watt power supply these days ?

Most PSUs run most efficiently when they're not running above 50% if their
rated capacity. Therefore, to save electricity, get a good quality PSU rated
at twice what you think you need.

Very good Shaun......:-). That is a very good way to look at it. In general,
a PSU of 350W running at max value may use more electricity than a good 700W
running the same components.
