I recently assembled an impressive workstation build at work featuring an Intel Ultra 9 285K CPU, MSI RTX 5090, and a solid 192GB of RAM among other high-end components. However, I'm facing a frustrating issue — the system simply won't boot. When I switch on the power supply, the RGB lights on the motherboard illuminate, hinting that it receives power, but pressing the front power button does nothing at all. I've even tried using a screwdriver to jump the power pins with no success. The only indication of life is those RGB lights.
Here's a rundown of what I've tried: I've removed the GPU, reconnected all power cables, ensured the CPU and motherboard connections are correct, and seated the RAM in various configurations. I've also cleared the CMOS multiple times and reseated the CPU without finding any bent pins. I'm planning to remove everything from the case and check for any hidden motherboard standoffs, and I'm open to testing the PSU, but I'm unsure how to do so. I heard that my motherboard might need a BIOS update to recognize the new CPU, but I'm not certain. Any advice would be appreciated!

Just a thought — is your power supply even switched on? I’ve overlooked that before, and it’s a quick fix! 😅
If you’re not getting a response even when shorting the power button connector, try the ATX connector directly. Short the green and black pins on the 24-pin ATX cable. If the PSU powers on, it might be the motherboard that's faulty, or vice versa.
Don’t forget to power it down and reseat those RAM sticks! Sometimes that little push is all it takes to get things working again.
It sounds like a classic case of a loose connection or something not seated properly. Have you checked all the connectors? Try testing each component in a known working PC if you can. Sometimes a new part can turn out to be faulty, which can be frustrating!
Regarding the BIOS update, there's no need to stress! All 200-series CPUs are supported from the first BIOS. Just ensure your power cables are firmly attached — the 24-pin and the CPU power cable. Try booting with just one RAM stick in the fourth slot, and clear the CMOS again.
Got it, I’ll skip worrying about the BIOS then. I’ve tried some of the suggestions but will give it another look later today.
Absolutely! Testing parts individually can help pinpoint what's causing the boot issue. Don't forget to double-check your PSU connections too; even a slight looseness can stop the boot from happening.
