Is this a sign of my psu dying?

[MehRepublic]

few hour ago(at the time i post this) my pc suddenly shut down, i was just browsing the internet (no heavy program running)

turn on the power and it fail to boot, only my mobo light are turning on

 

from what i can say its not cpu or gpu related, temperature is perfectly fine, no coilwhine sound

 

what make me say its my psu is it sometime fail to power on on standby mode, i can only power it afterward by unplugging the power socket on plugging it back or around 5-20 sec after turning on the power socket

 

is there anyway i can check this? troubleshoot it? any info missing?

 

i somehow manage to turn my pc on 5 min later...

 

System spec

I7-3770k (no oc)

Sounds like a dried up capacitor on the +5VSB. That explains the failed start-up attempts.

should i get a replacement? sometime it power on, sometime its not

 

warranty is still left few month(maybe its over) 5 years but its way to troublesome

you should RMA it. It should definitely be covered under warranty.

Well, I guess you could always wait for other people's opinions but unless you have a way of testing it in another system there is no way to be sure

the same thing just happen again, but this time it happen around 10 min after i turn on the system,

manage to reboot it again, i think i try to contact seasonic about this and probably get another backup psu if i gonna do the rma

i ask from the shop that i buy my pc, i and i got the best answer i can get

 

"should we charge u for this service(answering my/this question, not the RMA), u can send ur whole rig and "some money" and we will do the test"

 

BS, i guess i have to do this on my own
