PSU and CPU fans do not start when power turned on

post #1 of 7
Thread Starter 
The green light on the mobo (signaling there is power) is on though. The case is fine, I tried shorting the "power on" and got the same response. Is it the PSU or could it be something else? Oh, and when I turn the computer on, aside from a very short burst of fan activity (both psu and cpu), the psu starts making a sort of quiet buzzing-ish noise.

Most probably PSU, but if you can, test another PSU on your system, or your PSU on another.

Yeah, already did that, I forgot I had an old Sempron rig lying around. It's the PSU - the old generic one powers the sempron just fine, whereas M12II does not. Damn, not even a month passed and it's already dead. This sucks.

Seasonic isn't known for quality...

Try and get a corsair PSU, or a PC Power and Cooling.

Sorry, but i couldn't disagree more...
Seasonic is a good PSU maker, very realiable, but just any other brand, their PSUs aren't meant to last forever, and some live longer and other have a little less life spawn. Any high-end Seasonic PSU is as good as any other Corsair, Antec or PC Power and Cooling, as some of their own PSU are made by Seasonic and then rebranded.

Well, any electronic component (in fact, virtually everything) could potentially fail at some point in time. It's a small chance, but it nevertheless exists. And afaik, SeaSonic is a pretty good firm with a pretty good price/quality ratio. It's just bad luck. Though if the second one fails as well, I would reconsider my position

edit: whew, after 80 glorious minutes of public transport, 50 minutes of standing in line at the store, the first part is finally over. Fortunately, they seem to think the replacement would arrive by the end of the week, which is much quicker than I expected.
