[HELP] Motherboard probably dead ? SB_PWR not on ! Tags: Motherboards Last response: June 9, 2012 3:13 PM in Motherboards Share nyxfx June 7, 2012 10:02:09 PM 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?
