I'm up to finish building my PC, though since it's my first I lack

Mine is Intel BTX DQ965COEKR, and having consulted its documents as
far I felt competent to understand them, the ATX 12v required seems
in simple general term of wattage about 610W. cf.
http://www.pcpower.com/products/power_supplies/dual_cpu_selector/

Then lead by your wording of it (PSU selector), I finally found out
http://www.extreme.outervision.com/PSUEngine , rather better for
practical use than http://www.formfactors.org/ given by Intel.

Oh wow. That's the worst PSU selector app I've ever seen :-)

Required PSU wattage actually has very little to do with the
motherboard. The key components are the CPU, video cards and HDs. Note
that even a high-end system will generally draw less than 300W at load,
so a quality 350-400W unit is usually plenty.

I cannot agree here with your statements. Motherboard specifications
let see it otherwise. http://download.intel.com/design/motherbd/co/D5601901US.pdf
I'd guess the PSU selector of pcPower is partial to its brand though
has an appropriate database of motherboards and fit a simple choice. I
would have preferred one with several brand names - and price!

PCI-express 16x cards are more power-consuming than this, there's a
more significant change in wattage needed. In books and web-sites I've
consulted to build one's PC, none detailed PSU choice. Though this
motherboard PDF specifications stresses it quite more. The choice of
it isn't explained simply, calling for professional know-how. I must
confess not having read through the posts of this newsgroup either. I
feel being too well informed for a question a bit too technical; since
there's no comp.hardware USENET forum active anymore (or ideally
comp.hardware.ups), here is probably still a good place.

How many and which kind of cables come with a PSU is different from
one to another. Little indication too whether ATX 2.0, 2.1, 2.2 would
make quite a difference... I would want it to be fully compatible, long-
term buy and cause no trouble when upgrading at least the hardware
I've got now (mainly deduced from the possibilities of my mainboard!).

As that board doesn't appear to support quad cores and definitely
doesn't support multiple video cards, you're not likely to run into PSU
issues.

High end PCI-express are quite consuming and 610W wouldn't seemingly
be sufficient. I mean I want from the start to figure out, whether
this motherboard will justify, for me, upgrading it to its limits
without having to change PSU or not. Maybe though I shouldn't upgrade
the hardware I have here to its maximum; a long-term economical choice
would involve to buy another when comes time instead. No need either
for over-clocking. I figure out PSU choice could be quite technical
but shouldn't matter so much for hobbyists when building their own PC.
It could though become quite frustrating when hardware upgrade
wouldn't be possible only because of PSU issue. Be it by lack of an
interface on PSU or lack of wattage. Some little tech details in volts
and "rails" make me remain scrupulous. I like pcPower simpler answer
for that.

Lastly, as in the subject header, since my processor came boxed with
an ATX fan, should I expect here in Quebec retailers to trade it in
fairly against a BTX for me?

Don't ATX coolers fit in BTX systems, at least if you remove the
ducting? If it fits and works (even suboptimally), you're not going to
get any joy out of the trading laws. A proper BTX cooler would be
considered an optional extra.
