Ahoy hoy!
I have a new build I'm tryin to cobble together but I can't get it to post the first time.
I have a ASRock B650E Taichi M/B, Ryzen 7 7600x cpu, an EVGA 850w Gold, a MSI 2060, 32 gig of ram, 1tb SSD and a 1000gig HDD, all in a Fractal Torrent case. I've hooked everything up and can see the RGB and smart switches light up, but when I hit either power button I get no response.
I've reseated the cables, removed the GPU, reseated the ram, waited hours, and nothin, not even the fans kickin up. What Am I missin?
Update: sorry for the delay, works been crazy. The PSU has a tester so I was able to confirm the fans an PSU works. Unhooked everything and plugged it back in, same results.
Update 2: Electric Boogaloo: success! Thank you for all the help, culprit was either the power supply itself or the cables, but the fix was a new psu
Did you try taking the mobo out the case and testing it, the CPU and RAM? If you did and it's still not working, then I'd follow u/dcdc's advice and update the bios, the board could be on an early build that doesn't support your RAM.
Here's a link to updating your BIOS without posting.
And the latest (non beta) BIOS link.
