Question Spontaneous shutdown TR4

[mshedden]

Getting some random reboots and spontaneous shutdowns on a new threadripper 1920x system.

PSU is a Corsair AX860. Will 100% shutdown when running 3D portion of Passmark benchmark. Bang, power off, no lights, nothing and will not power on again for a couple of minutes.

Figuring the gpu is pulling a bit of a load and tripping out the (bad?) PSU.

Everything is brand new, otherwise running fine. Cooling is fine, so not overheating. Nothing o/c, ram @ 2400. Motherboard 20 pin and 2 cpu power cables connected, 2 pcie power cables going to gpu.

Ugh, hit post before done, edited it with info. Corsair ax860, CPU 44C, GPU33C, all new gear.

The fact it won’t do anything, no leds, nada for a couple of minutes after shutting down makes me suspect the PSU.

Replaced PSU with an identical Corsair AX860. Problem appears to be solved!!
