My new DZ87KLT-75K has difficulty turning on. When my machine is off the red "Power Supervisor LED" is lit constantly. When I turn on my machine, I get prompted with a message telling me that the Intel Power Supervisor has detected a "Catastrophic Power Event." If I press a key at this message, the Power Supervisor LED turns off and the machine usually proceeds to POST and boot to Windows 7. Sometimes instead of booting I instead get the red Power Supervisor LED combined with the memory error beep code (three beeps, repeat). When this happens the machine turns itself off automatically. Once booted to Windows the machine seems stable with good thermals and game performance. The power supervisor LED stays off when Windows is running.
My first thought was the power supply. I have tried two Corsair AX860i PSUs so far. I RMAed the first one because I figured if the power supervisor LED is lit then it must be a problem with the PSU. Today I got another of the same exact model, but the above symptoms persist. Corsair's website insists that this model is compatible with Haswell.
A separate but possibly related problem is that I seem unable to update the BIOS on the motherboard. I tried twice. Both times the machine shut itself off and went into BIOS recovery mode. I suspect this power problem is to blame.
Here are my full specs:
Core i7-4770K
DZ87KLT-75K
32 GB (8GB per DIMM) of Dual Channel Corsair "CMY32GX3M4A2133C11"
Nvidia Geforce GTX 780
Samsung 256GB SSD
Western Digital 2TB HDD
Corsair AX860i PSU 860 Watts
Do you think it is safe to use this machine until I get a fix for this? Could using it damage the components?
Any help would be greatly appreciated!
