I cant use 5x4090 turns off if run hashcat with the parameter -O

[tomei]

I use this hardware:
5x4090 msi ventus
motherboard asus pro ws w790e-sage se
cpu xeon w5-3425
ram 64
power supply super flower 2x2000w
win 10

power supplies are connected like this 2x4090(motherboard+cpu+pcie8pin and 6pin)+3x4090 on the other power supply
Im using x16 raiser gen 4.0
if you run benchmark hashcat with parameter -O
hashcat.exe -b -w 3 -O
there is a click power supply and the system reboots.
If you run benchmark without the -O parameter everything will be successful and the system will not reboot.
If you remove one gpu leave 2x4090+2x4090 then everything works.
tried 3x4090(motherboard+cpu+pcie8pin and 6pin)+2x4090 does not work, also reboots with parameter -O
3x4090(motherboard+cpu+pcie8pin and 6pin)+1x4090 works!
Help where to dig, what to do?

And as you might have realized, it doesn't work with 5 video cards. If I plug in 4 or less, everything works.
All video cards have been tested to make sure they work.
