Hello,
I recovered an Asus z97 Gyphon Armor Edition.
I installed my old I5 4690k on it with Gskill DDR3 1600 4Gb and a ventillo on the cpu pin
The problem is that the CPU_OV led (stays on), the power supply starts 3s then goes out (in loop)
No access to the bios so no display (I specify that it is not the CPU led) The leds which check the key components; CPU, GPU, DRAM, BOOT DEVICE LED are all off.

it is set to default, so it should be off
What I tried:
1: Flash of the bios (tested 3 versions) in usb with nothing on the motherboard, ditto with the cpu and memory.
2: connection with another 650W power supply
3: Installation of a GTX 970
4: test with DDR3 Balistik
All the stuff I try is working on my PC.
Update: I have unplugged the _8pins CPU power supply, the CPU fan and the power supply starts normally.
I even tried to connect the CPU power supply only with 4 pins and the same problem with loop reboot ......
Thank you for your help
