Yes, that PSU should work. That PSU can deliver 360W maximum, which means at 230V it will draw 1,57A maximum (230V x 1,57A = 360W). At the 12V side it can deliver 30A (12V x 30A = 360W). So the household plug only needs a 2A fuse, because it's at the 230V side of the PSU.

20A @ 12V should be fine.
20A @ 12V = 240 Watts. Depending on your household location, that would be
around 1.4 or 2.7A at 220 or 110 VAC; modern cheap power supplies being approx 80% efficient.
ok so im gonna sit down and think whether to get 200/250cfm with symprojects fan controller. less power but been told more than enough and is all plug and play.
or the 380cfm delta fans with the arduino bypass etc.
could i use a pc power supply? i have an old one lying around.
also would the arduino need any cooling or anything?

Adding a fan controller seems less plug and play
than connecting Arduino PWM directly to 4-pin fans...
PC power supplies come in many different specifications.
Most will require hot wiring some pins
to enable power without being connected to a motherboard.
Turn a Computer Power Supply into Bench Power
An Arduino typically uses between 286mW and 1.3W of power
ok probably easier to just buy the one i linked.
will the arduino need cooling or anything?
as far as permanent connections instead of dupont i guess some speaker cable will do which i will solder.
can i just use the dupont ends soldered onto some thicker wire?or should i remove the headers on that side and solder the wires into points 9 and 10? (after testing with dupont ofc)
does the ground from the arduino going into the powersupply connect at the same terminal as the ground from the fans or should i use a seperate terminal for each seeing as this psu has multiple?
this is the diagram im thinking for use with simhub. does this look correct?

Some Dupont wires solder poorly.
Wires are antennas, both transmitting and receiving.
Since I have it, DMX cable works for PWM signals. USB cable would be another option.
Consider short power leads from 12VDC supply to motors instead of overkill gauge.
Stranded copper insulated 16 AWG twisted pair wires looped thru a ferrite bead
would be my preference for power:
FWIW, I use STM32 and ESP32 boards with Arduino code,
instead of Arduino microcontrollers.
STM32 and ESP32 support more PWM pins without bit banging,
allowing a single controller to drive both fans and harness tensioners
as well as e.g. input switches.

1/4 to 5/4 Watt power is not much heat, but anything is possible
if pathological packaging prevents airflow or thermal conduction...
Packaged like this, mine has no trouble:
- hot-glued to corrugated cardboard
- corrugated cardboard hot-glued to supercapacitor module for massive power filtering
- 2DOF harness tensionner with Fly PTmover

the runs from the power lead will be about 1.5m for each fan. is that considered short?
handy to know regarding the boards. im guessing simhub proces is the same?
Not by me; power wiring from supercap to motor pigtails in above image is about 9cm.
