Asus Z170 Pro Gaming 8-pin ATX12V Issue

SilviuParvu · May 20, 2016

After finishing the PC Build, the motherboard's LEDs will turn on, but the PC itself won't start. But if I plug out the 8-pin ATX12V connector, the motherboard LEDs, the chassis fans and the GPU fans will all start, and again the PC won't turn on. Any idea how to solve this problem?

It looks like a short at the CPU level. Check the CPU cooler backplate. See if properly installed. If ok, try testing the board outside the case. If still the same, try removing the CPU, taking a picture of the CPU socket and posting it here.

Also make sure using the proper 4/8 pin for the mobo connection - we've had a number of people plug in an 8Pin PCI-E connector

Actually, I think I may have put 2 4-pin PCI-E connectors there too. 1 fit fine, but the other was the wrong shape. I plugged both in and the board is running fine. I've found 3 other 8-pin cables in the PSU box that WILL fit properly. They are labelled CPU, AE04 and AE09. Can you tell me which one I should use..?

Tere are no 4 PIN PCI-E connectors, this is prob the correct cable 2 4pin connectors on the same cable?
