Hmmm...it seems like most people who have their psu seated on the bottom of the case have the fan pointed downward. I have my psu the other way around, where the fan points up. Is there a reason why most people have it the other way?

Theoretically pulling in cooler air from outside of the case, vs the hot inside.
Obviously depends if your case has a opening on the bottom, though (ideally with a dust filter).
Interstellar is what would happen if I ever open up my PC
That's not true. The exhaust fan is pointing out the back of your PC. The fan that you're talking about is the intake. It doesn't blow air anywhere. It sucks air in. That means it's fighting with the GPUs fans for the air in that space when it's facing up.while this is technically correct, does not precisely explain the whole thing.
By pointing the PSU fan upwards, you're actually blowing hot air directly onto your card(s) which may have some adverse effects, specially if you overclock.
This can be countered by building enough positive pressure within the case itself by placing some intake fans on the front, and having the rest (back, PSU, etc) blow all hot air towards the outside.
For this of course, you have to also consider how much positive pressure you have built which in most cases, is required to be higher than that of your components and their heat convection properties (all heat tends to go up), but which can also be solved by placing top exhaust vents.

I don't think GAF can handle its glory! This picture is a few years old, and I did some much needed cleaning up.

I've been expecting you.
What monitor is that in your second pic by the way?
Based on the cleanliness of all of your equipment, I'm not about to take a picture of mine.
I don't know how you all do it.

It is the Samsung UD28D590D 4k monitor. $600 when I got it but on sale for $500 at the moment.
so many colors, this is cool.
please excuse the crappy diagram....
unless you have delta fans which can dissipate heat fast enough,
or place the PSU somewhere near the front/middle of the case,
it will catch some of the hot air and "cook" itself
Assuming the PSU is at the bottom of the case:
PSU fans are intakes. If you have the fan facing up then it fights with the GPUs to collect cool air from the front intake.
If you have it facing down it will get fresh air from the outside of the case.
In carpet/dusty environments it's better to have the PSU fan facing up (else you'll get a ton of dust and poor airflow through the PSU), otherwise facing down is better.
I think you are way over exaggerating the PSU grabbing it's own exhaust since that hot air will want to rise.
I try not to over-exaggerate, but I'm seriously OCD about case temperatures and airflow.
Specially since i used to have these rigs set up for crypto-currency mining running 24/7 ..... 1 degree would make a world of a difference.
And as an added note, .... single fan PSUs wont work as intakes because by the time the cold air they pull in has passed through the circuitboard and heatsinks, is already reached "above room temperature"
When I meant intake, I meant the fans bring in air into the unit and exhaust out the perforated rear side. That's why they wouldn't blow hot air into the GPU as you said in your first post.
That's actually a relatively small one, as I was limited to a height of 15 cm
It looks larger because the case is small (for ATX).
Dude, you have a cat in your PC.
Old parts have to go somewhere right ? LOL
It's a 970 instead of the 770 now though.
4790K 5GHz
2x 970 1500MHz
Runs cool and quiet
Can't really get a decent photo at the moment.

It's a Jonsbo UMX2.What case is that ?
