hi guy, I am using nicehash legacy.

My rig always restart if I set my afterburner power limit to 90, now I am running 80. Got fews times after I install the Gigabypte PSU (power limit 90), I saw 3 of the GPU stop working after few seconds

Also I am using NH to mine, so if I turn on Lyra2 my rig also will hang and restart it self, now I only can only Equihash and Neoscrypt.

May i know what is the problem?

My rig spec:
-Asus EX-B250-V7 x 1
-Intel G4400, 3.3 GHZ , 3MB Cache, LGA1151 ( BX80662G4400)
-Corsair ForceGT 120GB SSD x 1
-Corsair HX1200 x 1
-Gigabyte Xtreme Gaming 1200w x 1
-MSI GeForce GTX 1080ti x 6
-Corsair DDR4 2400MHz 4GB x 1

I connect Corsair HX1200 to motherboard,SSD, CPU, 3 riser and 3 GPU, and Gigabyte Xtreme Gaming 1200w to 3 riser and 3 GPU.

MSI Afterburner Setting For 2 PSU IF I set the power limit to 90, rig will restart it self or power on the 2nd PSU will trip/cut off.
Power Limit - 80
Temp. Limit - 80
Core Clock - +95
Memory Clock - +600
Fan Speed - 80

MSI Afterburner Setting For 1 PSU( work fine)
Power Limit - 100
Temp. Limit - 80
Core Clock - +95
Memory Clock - +600
Fan Speed - 80

Anyone have this problem?

**Update
Today reformat my rig and add new ram to 8 gb, and new SSD. And the problem still the same

Problem Solved
For restart - change riser and SATA cable port
For trip - PSU failure
