Power Issue

[XanderTheLink]

Hello All

I need some help I was building a new pc to replace my current one. When I turned it on the only thing that seem to be working was My HDD which I could tell was spinning. I tested the power supply and got the following screens.
I thought it was my motherboard now I think it's my PSU.

This is the seventh PC I've built and the first time this has happened. Any Ideas

PC Specs.

Ryzen 5800x New
Gigabyte x570s New
32GB Ram (From the PC I'm replacing)
Used 1080 ti 
Thermaltake Toughpower GF1 PE 850 New

You certainly have a manual to explain fault codes. What does the F means for the +12V rail ? A fault could be caused by a faulty PSU or because something was tripping some overcurrent protection.

Take time to check if all cables are correctly inserted into their sockets and the insulation is not chipped and creating a short circuit.

The basic test to do is to use another known good PSU to test if that changes anything.

A 850W PSU should be able to run your system, but if the PSU is indeed faulty, you can't do much except return it or RMA.

Good luck !
