I just buuilt my PC(first time), then i turned on. It was working fow 5-10 sec, after few red lights flashed on mobo(no sound), and it turned off. I couldn't run it, then I took PSU out, connected only 24 pin mobo cable, and it started-all fans which plugged in on mobo and CPU fan. But when I also plug in a CPU 8 pin it doesnt start.

And optical drive
I think my PSU is strong enough for these.
It should be strong enough to start even 24 and 8 pin connectors(just these 2)
