This is a record of my newest, starting with my first 80+ model, and not 
including
any that came with any PC acquisition:

All are used with single CPU motherboards, roughly half with IGP video, none 
with
discrete GPUs that take 2 slots or require separate power connection, and only a
very few GPUs with active cooling. Maximum HDD/SSD count is 3 per, but most have
only 1. Thus, my PCs' power requirements are relatively modest. Maximum CPU core
count per PC is 6. Max CPU TDP is 125W, in one only (running on a 430W). All the
rest are 85W TDP or less.

Nearly all those I bought before 80+ eventually required recapping within 5 
years
of age, or warranty replacement. The EA500 was returned because it always shut 
the
PC down during UPS transition from 120V to battery. 2 of the other Earthwatts 
also
needed recapping.

AFAICT, I've never overloaded a PS that wasn't itself failing.

Since dual 12V rails became a thing, I've always avoided such models - KISS.

I buy on sale rather than immediate need. So, my cost has typically been in the
$20-$30 discount (or rebate) off regular price range.

I generally find:

Seasonic
EVGA
Corsair

to make reliable power supplies. I can't speak to AC supply
problems, because I always put any computer I care about
behind a UPS.

The Seasonic S12III series has several units in the $50-75 range
according to required power.

Really? I've used a number of cheap Chinese 300-400W power supplies in the $20 
range and they all worked for years without any issues.

   Does anybody how to make an ATX motherboard boot without having to
press the 'power' button everytime? That is, I want an standard AT
behaviour: if there's power in the line, then I want the machine running
without having to press anything.

There was a long discussion of this on slashdot.org last week; look
in their archives.

The solution is to electrically connect (certain) two of the wires 
in the bundle that plugs into the motheboard, or else to connect 
some  of the wires leading to the power 'switch'.  The deatails are
over there.

I believe that's incorrect. The power switch is a push button switch;
one pulse on those pins will switch the thing on, another will switch it off
(or suspend mode, as configured in the BIOS). It might be that holding the
switch in (ie connecting the two pins permanently) does the trick though.

 TIA!

Check your board's manual, BIOS setting section

This is more than likely a function of the BIOS of your
motherboard. Look through your BIOS and see if it supports this
functionality. If it doesn't you're probably out of luck.

Your BIOS manual might tell the tale, some careful experimentation might as 
well.

Insert standard caveats here. Remember 120V at 15 amps = Crispy Geek.
