Remove your GPU, unplug all connections, extract the RAM and check for boot errors on the motherboard. This appears to be a PSU issue—it attempts to power on and then stops unexpectedly. Let's eliminate basic causes first.
@Whatisthis Even simpler, remove the power button from the motherboard header and try to short start it with anything metallic, like a screwdriver tip. I've seen this from shorted power buttons. If that doesn't change anything, then you know the power button is good. Or if your motherboard has an onboard power button, then just use that with the external power button removed from its motherboard header to make sure its not shorted.
I attempted a different approach by disconnecting all wires from the JFP1 and placing the reset button in the power connectors. The issue persisted. I'm unsure what's happening. Have you seen any other attempts? I've also tried removing the GPU to lower power consumption, but after installing a new PSU (the Cooler Master MWE 450), the system would shut down after a few hours without errors—just a power cut. Sometimes it powers on normally for 8-12 hours before failing and restarting repeatedly. The frustrating part is my motherboard is out of warranty, and I suspect an issue with MSI. They initially claimed it was a scam after I pre-ordered the product, which had problems like no display. After about a month, I received a refund or replacement policy, but it took over 30 days. I reached out to Acro for help, but they sent the item back after a few days and asked for a diagnostic fee of around $5. They also suggested I submit the motherboard for testing in three days with a charge, then get an estimate for repairs. I've contacted Cooler Master since my PSU is under warranty, hoping it might be faulty. However, my V750 80+ Plus is EOL, and they offered a lower-end MWE 750 V2 80+ Gold instead. I’m asking for a better PSU than the one I have. Thank you all for your responses—it really helps!
You attempted two power supplies, both failed. Likely dirty electricity from your wall outlet caused the problem. Consider bringing your setup to a friend’s location to test functionality there. Do you have a UPS or line conditioner available to confirm the issue?
