Hi, I recently assembled a new PC. when I turn it on, all fans and lights turn on... for one second, after that all components turn off, 3 seconds later it turns on again and so on repeatedly.
it doesn't even POST.
First thing I did was to test the system with other (VERY old) power supply everything worked fine, no problem.
so I thought the new PSU was damaged, for my surprise, when I put it in other (VERY old) computer... it work!!
I have build a lot of systems and it's the first time I see this
How is it possible?
Is there a problem with the psu?
I have the same problem. Did a new PSU solve it for you? Thanks
well yes, I got a corsair CMPSU-650TX, and it's working fine
but I don't know what was the problem, the Antec PSU is working PERFECT in my old computer.
As I said before this is the first time I see this, I don't know if it's a compatibility issue, or something else
