Power supply safety...

[N64CUBE]

Long story short, I took apart a psu to get a screw and avoid shorting it. I have to reassemble it now. Is it safe to do that or am I gonna have to get a new one...

If it is okay should I be aware of anything?

It's safe. Most PSUs auto-drain capacitors once they are turned off. Just be careful.

Sometimes you are able to discharge capacitors but just be careful. You took it apart fine, just work in reverse

[manikyath]

as long as you reassemble it in pretty much the exact same way and didnt damage anything, it should be fine.

 

just be very careful.

Which way would the is fan go?

Which way would the is fan go?

with the sticker facing down.

with the sticker facing down.

Okay. Can the wire go any direction as long as that sticker faces down?

I think so. Have the wire as close as possible to the fan header where you need to plug it in.

the arrows you shown show fan blade spin direction, and airlfow direction.

depending on your preferred airflow setup, place your fans in the right direction. (generally, with the label side pointing the direction of airflow)

EDIT: most modern psus have the fan as an intake, btw.

As stated, the sticker goes down, and that plastic cover will be towards the vent.

While sticker down is the correct answer, it doesnt necessarily teach him why. Like someone else pointed out, the arrows indicate direction of airflow and spin direction. The arrow that denotes airflow should be facing into the power supply. The fan is supposed to cool it, so it has to be set to intake.
