Weird electric noise coming from psu at random times

[Andres_8]

Well, this is odd, my psu starts making like clicky-electric sounds every like 2 hours, average, it sounds for like 3 secs then stops, is it dangerous?
btw is a 650w corsair psu that came with the case, It is 3 years old, is it time to change it? D:

Yes, an unstable power supply will start to cause all sorts of weird stability issues. PSU's are rated in tiers (tier 1 being the best, 4-5 being cheap. Here's a a link to a guide for that.

I would get one that's at least tier 2. The cheaper ones use crappy sub-par transistors and other components that are low quality.

But is there any risk of still running with that psu?? the electricity noises appear very rarely now that I think of it, not every 2 hours, but sometimes it keeps for longer, what could be the consequences of running with that??
also, my motherboard is a cheap 970a-d3 from gigabyte, it is 3 years old, can it cause some kind of trouble? it has a 4+1 power phase and running with an fx-8350 a coolermaster hyper evo 212 and a gtx 960 attached to it, can they like, drain more power than it can deliver and slowly kill it?

I highly doubt it. More accurately what will happen often is the the 12V rail(s) will start to give out inconsistent power -but you would be suffering from crashes/stabilty issues if that were the case.

That noise you are hearing is probably the PSU fan starting to die.

well, thanks a lot m8. Another issue btw, when I use the mouse to move myself around the map when using the black ops 3 map tools which came out as an open beta yesterday, an annoying buzzing sound comes from the motherboard, it only sounds when I drag my mouse around the 3d modeled map xDDD, what could be causing that? it happens in every usb port, is it some kind of negative feedback?
