Welcome to the forums, newcomer!
You've provided 3 lines of text though we're going to need a lot more info. When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
Paperclip test worked on the PSU
The paperclip test is flawed, it tells you that the PSU can power up but what the test doesn't tell you is how much power the PSU can effectively output to your build.
and mobo was just sent in for warranty for a separate issue.
Which was?
System has more than enough wattage, that shouldn't be a problem.
To rule out a shorting issue, did you breadboard your parts?
i3-12100f
Rx 580 2048 SP
it's a SATA SSD I got from taking apart an old optiplex
b660m pro RS
Assassin x 120 R SE
16 GB of Corsair vengeance LPX 3200 MHz ddr4
Corsair CX650M, about half a year old
Thermaltake MATX case, couldn't find the exact model.
Windows 11
Dell monitor that works fine with every other device in my house
I tried rebuilding outside the case, it had the same issue.
Sent in the mobo for having fan spin for a few seconds and then nothing.
Nothing happened that should've caused it to break, I just went on vacation for a week and it stopped working.
