Psu component ticking/clicking sound since June'16, overheating(i feel it through case) and little hang during gaming recently.

There is possibility that the current flow in our house is not stable as there was a case that psu started to clicking when aircon is being turned on and stopped clicking after awhile when aircon is turned off.

There is also a possibility that the psu has reached it's lifetime, but it's just 2-3yrs old. It could survive for atleast 5yrs according to manufacturer co.

Should I get a new psu? or an AVR? UPS?
The clicking sound is smtg similar to this video

I'm sure it's not harddisk or fan, i had already tried to unplugged harddisk and stopped the fan but it's still the same. The sound is coming out from back of psu. It usually occurs after few hours of gaming and the startup of pc.

Any advice please? Thanks

well....i mean case and psu fan
that sound is coming right inside the psu...(i opened it up and put that fan aside too) and the sound is not coming from the fan...it's from one of those components in psu...but i'm not sure which one is it

hmm...it's ok thx for ur answer btw
what's high frequency switching about?
 


Oh it's just what makes a switchmode power supply a switch mode power supply. It starts out as high voltage, low frequency alternating voltage and current. It is then rectified and filtered into high voltage direct current and then it is run through high frequency switchers to make it high frequency, high voltage alternating current/voltage, and because it is high frequency the transformer can be smaller, so after the transformer and rectifiers you get low voltage direct current.

Yep. :pt1cable: fun stuff. Sounds more confusing than it actually is.
