Can I still use this while waiting for a new PSU?

[kitnoman]

So I already bought a new PSU. But it might still take 4-5days to arrived. Technically there's no issue power wise, but my psu started to vibrate loudly at start up and would eventually settledown after a while. I think it's the fans, but I really don't  or know how to troubleshoot psu. I really need to get my work done. So my question is, do you think It's still "safe" to run this pc while waiting for the replacement? And what happens to a psu that does not have a fan, in case the fan really fails? By the way, the psu is thermaltake smart se 730w and I had this since 2015 I think.

Yeh that's just a bad fan bearing. it sounds like it's at least spinning so you shouldn't have any problems

Thank you, for the moment I can't game on my pc or anything that draws a lot of power. I've notice that the fans ramping up and causes an even loader squeaking sound when the pc pulls more power and creates more heat. Good thing, I only need a browser and excel to work lol

In my spare time, once I got my new psu, I'll try to play around with this. Can you tell me, generally speaking, just how long should I wait so the the psu is fully discharge? I'll probably watch a few more videos but I think it has a 140mm fan and I also have an extra arctic 140mm. I hope I don't burn myself in the process though

Bad fans can run for years in a state like that, its more that its annoying and you know its going to fail eventually that dictates replacement.

There is no rule of thumb, it depends how its designed.  This is why people generally advise turning the PSU off then pressing the power button on the PC, in the hope that the PC trying to turn on drains the last drops of power out of the PSU.  But the only way to be sure is to find the big capacitors and short them with a screwdriver, being careful not to touch anything else (or your finger) at the same time as you don't want to discharge them into another component.

I don't have any real technical background as I took liberal arts, so I might not be able to locate correctly the capacitors. What I know are bits and pieces from watching my uncle(computer sciences) as a kid and videos. But I do like playing around with pcs. If I'm not yet confident at shorting the capacitors and just leave the psu for a while, let's say a week, will it drain itself or will the capacitors keep whatever charge it has left?

Then it's probably not a good idea to mess around with a PSU. Unless you really know what you're doing you don't want to mess with one, they can kill you if you do something wrong.

depends on the PSU, but I've heard of units keeping charged for upwards of a year. it's just not something you want to mess with.
