Hi, need a confirmation. When I on my PC, thre is a sound in my PSU. Hard to explain how the sounds like but it's like a fan balde is hitting something. Or like a clicking sound. When I switch off the PSU, it's stop. The PSU fan blade did not hitting something coz it's still running when I switch off the PSU before it's stop completely and no sound. Only when PSU is active. The sound continous from I on the PSU until I switch off. This is new PSU I just bought and it's happened the first time I'm running it. First few minutes, the PSU running fine without any noise. Only after that it's start making noise. After few try, I never on the PSU agian coz afraid it will damaged other this such as mobo, ram etc.... Please advise me coz the shop said it's normal!!!

If i open the fan case, it will cause the warranty void is I'm not mistaken. Hmm.... why he said it's normal??? He promised me to repair the PSU.... That one should be exchange 1 to 1 right?? Not repair it coz the problem happened on the day i bought the PSU.

Has send back the PSU. He said will check what is the problem. If fan that , he will replace the fan. If electric component problem, he will exchange it. Hmm..... tired of waiting . My new GC also can't test till now due to PSU.....

Last night received new PSU from the seller. Confirm my PSU damage. The sound came from the capacitor or transistor (can't remember clearly which one is damage). So, he give me a new one coz that can't be repair by him. If fan problem, he will repair himself. One more thing I'm shock when he told me is that i'm so lucky coz the PSU never explode.........!! So, be careful....... TQ all for suggestion and comment.
