need help with s17 pro error message

I just got my hands on an s17 pro and I'm running into some issues. The rig only stays on for about 5 to 15 minutes before it shuts down. I've included the error messages I've been getting below. Any advice would be appreciated, thanks from your friendly boomer dad.

I would say you need a new psu.

new psu is almost certainly need. do you have proper power 210 to 240 volts? if you do. try opening gear and using only 1 of the three hash boards. if that works try using two hash boards. more likely  the psu is dead. if the power is 210 to 240 volts. once in a while you can run a board or two boards if the psu is weak. finding a new psu will be very very very hard. good luck on that.
