should the psu fan face up or down?

[knighttime]

im ready to install my new psu and i dont know if the fan is supposed to face up or down?

[Snapjak]

Face it down. Cool air in through the bottom.

If it's an old case that mounts on the top, get a new case that mounts on the bottom.

top mount, down

bottom mount
if its on carpet, up, hard surface, down

its a corsair 750 watt. peripheral and sata i know its important to plug the wires into the correct slots but as long as it fits am i good to go or can i fk something up?

[tacoshy]

depends... that fan on a PSU is an intake and emnt to cool a PSU. if it is top mounted you have to mount it facing down so it can take air from the case.

if it is bottom moutn you either have airhoels in the bottom for that exact reason. if not you have to turn it upwards, unelss you have a PSU shroud. carpet is not an issue. every PC with a bottom PSU mount shoudl have airholes as mentioned and standoff for the case.

if it is modular make sure not to mess up SATA, CPU and PCI-E, Espaically if you place SATA PSU cables not in the SATA ports of the PSU you could emss something up.

its ibuypower prebuilt im goona look right now for airholes on the bottom of the case im sure they are there

i used to have mine suck air from inside case to outside and i killed mine in 3 yrs

no half decent psu should die because of that... otherwise every PC 10 years ago should have died within 3 years.

i cant find the back plate i took off that holds and screws the psu in place. can i still install it if i cant find it? nevermind i found it

Pretty sure it will only screw into the case the correct way up but dont quote me on that.

carpet can be an issue
if the case is sitting on carpet, it will block the intake vent for the psu, and the psu will overheat with the restricted airflow

i plugged most of the slots in right now i got three thick cords hanging out and the pc wont start. im almost ready to give up can someone please help? i dont where they plug into there not matching up to any slots

[tacoshy]

So will it when you place it upwards beneath a PSU shroud blocking the air as well... Besides manufacturer tired are no idiots. If they make authors in the bottom for the PSU the case itself will be elevated with standoffs to allow airflow.

[knighttime]

the psu is fitted the right way

Mounting a PSU is not keyholed. You can indeed mount it the wrong direction most of the times.

OK you have 4 kind of cables for the PSU.

CPU:
Has a 4+4pin cable most of the time and connects to the motherboard on the top side.

MB
Stands for Motherboard and is a 24 pin cable most of the times that fits into the right side of a motherboard.

(SATA) POWER
Has multiple L-Shaped cables called POWER actually but on a PSU cables as SATA. It should connect to every drive you having (despite M.2).
That ports on the PSU can also be used for Molex (trapezoid shaped cables).

PCI-E
Those are cables to power GPU's with 2x 6+2pins.
