I have had this issue in the past. I disassembled the entire PC and put everything back together and It worked. I assume there was a loose connection somewhere and the process of taking apart and putting back together solved it.
Also, you can buy adapters to convert atx to at so you can use a modern power supply.

The SYS Fail 8004E is related to loss of communication between the WS-CPU (Let) and the RT-CPU via the Basic Bridge Board (BBB)
Bad Connections; damage Capacitors; something pulling down the power supply voltages; such as a bad keyboard; board; fan on WSCPU or RTCPU; bad Spinning Hard Drive;
mixing fast CPUs with Slower CPUs; poor Board Connections; Corrupted CMOS BIOS Settings; Grounding/Noise issues etc.....

Hello
Thank you so much for your replies. What i did so far:
1. I made 4 industrial PSU connected and work as one powerful power supply (I have +12; -12; +5 and -5 V now). So I have no more doubts related with junk power supplies.
2. I changed all the capacitors on the WS-CPU (some of them seemed suspicious).
Since then (10 days ago) I got the fail only once. That's why I unplugged the WS- and RT-CPUs and plugged them again (4-5 days ago). I hope the problem solved.
One question: Are there any capacitors I could change on the BB?
Thank you one more time, guys!

Any ideas if this issue was solved? I am having the same issue sporadically with our one CNC machine.

If you have the BIOS cmos parameters on the Real-Time CPU motherboard corrupted by a low battery this can happen.
The board would need to be reflashed or setup on a bench.
Also check that all CPU Cooler fans are running and that the CPU heatsink compound if present is not all dried out.
Some RTCPUs such as the 3-424-2168A02 had a jumper setting to slow the processor speed down some and this may help.
Poor Grounding or board seating can be responsible. etc...
