Hello...

I bought the Sabertooth Z77 motherboard and an AX650 Corsair psu.


The problem is that after I installed all my pc components ( hdd, sdd, gpu , cpu, cpu stock cooler, etc...) , I tried to power on my system but nothing happened: no fan noise, no leds....


My first thought was that my psu was dead, so I tried it in another PC and it worked.


I noticed that my SB_PWR ( green led) is always off , for me it is really strange because even thought it is broken the led should turn on.


Can anyone help me please?
