What do you think?

Yes, I noticed that PSU.
Did you notice it "looks weird" ?
That's an SFX, not an ATX.

"main difference is its reduced dimensions"
It doesn't belong in the "power supply bay"
of your computer. It's for another type of computer.
Apparently, there are adapters for SFX to ATX.

So now you're back with the $91 one,
which is an ATX.

A lot of the candidates are the same size,
which you should check via visual check with
your scale. The 5.5" one, the housing can be
a bit shorter, because all the wires on that one
are fixed. (The cables don't unplug.)
When the supplies are modular, it adds to the
length of the casing.
If you think this isn't going to work, you
could shop for a lower power unit.
If you have a Kill-O-Watt meter, you can do a
total power measurement via the AC plug, and
that establishes the ballpark for each machine.
For example, I have a big video card in the Test
Machine right now. The Kill-O-Watt (which is currently
connected), reads 100W when the machine is idle.
It reads 350W when Furmark is running. It measures
around 200W when running Prime95. Those are examples
of tests that heat stuff up.
And based on that, I know roughly what size PSU
that would work for the system.
You have video cards which are similar to the
cards I normally buy, and I could probably easily
shave 100W off the size of PSU I buy today. I
could go shop for a 500W one for example.
If the casing is really too long to fit nicely,
you can go through the next lower range of supplies
and find one. Maybe it would be smaller.
You want an "ATX" supply, for the
3.40" x 5.90" x 6.30"

faceplate
dimension
The SFX, the holes in the faceplate of your
computer, would not align with the threaded screw
holes on the SFX.
The ATX on the other hand, the screws line up, as well
as in some computer designs, there is a short "lip" that
sits underneath the computer case end of the PSU and
holds it up. That takes some of the weight off the
screws.

I tried the 500W tier, and didn't really like what
I was seeing. Then I tried the 550W tier.
OK, this one looks sweet. First I put your $91 one for
comparison. Then the 550W one. You'll need to check the
wire length.

That's about as low as I'll go on the lower rails,
and still buy a product. That's my exact limit on modern supplies.
The length of the cables for the 550FM is here.
