Boot loop PSU clicking noise

[Scopey]

Hi,

 

My pc won't turn on properly and I can't figure out why. After turning it on it turns off after a few seconds and the PSU makes a click sound. I've tried a different known working PSU + cables but the issue remains. No display output at all.

 

This system has been working fine for years but suddenly developed this issue overnight.

 

 

Parts list:

CPU: i7 4790

Motherboard: Gigabyte GA-Z87X-D3H rev 1.1 (removed CMOS battery for troubleshooting)

PSU: CoolerMaster RS-650-AMAA-G1

RAM: corsair 1600mhz DDR3 8GB x2 (only 1 stick for troubleshooting)

Sounds like just a relay. Any half decent PSU has a relay to bypass the NTC thermistor on the input side. The click is not a cause of any issues, it's just a sound the PSU makes when turning on or off (from the motherboard's signal).

Good to know, thanks

Could it be a dead motherboard? I'm really out of ideas at this point.

its true some psus can make sounds like this - but it's not always a good thing, it could be over regulating or something,  ie i had a similar issue (it would just crash tho)

 

replaced the psu with a Corsair RMX, no issues since  (and no clicking)
