Motherboard shuts off immediately on new build

[aashton482]

So I've gotten the components to build an ethereum mining rig.

The specs of the system are an asrock z370 killer motherboard, 4x nvidia 1070ti on risers, 1 x 288 pin 4gb ddr4 ram, and an intel celeron g3950 kaby lake 3.0 ghz cpu, 2x roswill 1000w bronze power supply.

I've tried the system with two different cpus (the other was a kaby lake 2.9ghz), I've tried both power supplies individually, and tried it using only one gpu in case it was drawing too much power. Every time the system is switched on it immediately shuts off. The power supply and motherboard both kick on for a second and the cpu fan spins but it shuts right down. The motherboard does not offer error codes so I am not sure what the issue is.

Start pc with cpu and onboard graphics only without gpu. Do you have mining rig case to stand your GPU or they are on pcie extender?

The GPUs are on risers connected through PCIe. We've tried without any GPUs and with a single GPU

z370 killer motherboard support only 8th gen CPU. Intel Celeron g3950 kaby lake is 7th gen. You probably want to get Z270, H270 or B250 to guarantee compatible. Z170, H110 and B150 may required bios update first with 6th gen CPU.
