ASUS tech support doesn't even help you, they just keep pushing you for an RMA. BUT THE REAL PROBLEM FOR ALL IS the 3 pin connector for the cpu . That's the culprit, You need to NEVER connect to the cpu power 3 pin female connector to the mobo 3 pin cpu fan male connector . You have to use the 3 pin female connector from the CPU on the 4 pin male connector just to the right of it on the MOBO called the cpu fan optional, it is a 4 pin male, but you use the 3 pin female cpu connector there and the embedded slot that places it in the right direction IS USED leaving 1 pin unused> so spread the word...the 3 pin male connector on the sabertooth FX990 is useless.

I had the same problem: ASUS Sabretooth 990FX with AMD-FX6300, 16 GB DDR3 RAM. RED CPU always on, and no signs of life except for LED indicator that power was on. Got a power supply checker...all OK, got a MB checker...no POST. Pulled CPU and replaced with another from Amazon (did I mention the great customer service? Replaced the CPU chip after I explained. With second CPU, board booted, red CPU LED went out, and I in the BIOS Setup Screens. Looked closely at first CPU--> bent pins in one corner (very hard for old eyes to see). So the red CPU LED being always on meant something that was useful.
