ASRock X470 Master SLI not powering up

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,
I have problems setting up my new system and wanted to ask for assistance.

My parts list:
Mainboard: ASRock X470 Master SLI
Processor: Ryzen 2700X
PSU: Cougar 700 SX
RAM: G.Skill DIMM 32 GB DDR4-3000 Quad-Kit (F4-3000C15Q-32GTZR, Trident Z RGB)
Graphicscard: Palit Super Jetstream GTX 1080 ti

I currently have the issue, that after putting everything together, the system does not even power on. Yes I have double checked the 24pin and 8pin + 4pin power connections.
I tried with different RAM configurations (only one DIMM in A2).

But after powering the system, only the chipset starts pulsing and when I press the power button nothing else happens. No spinning fans, no "powering up". - Do I miss something obvious?

Is there an even more minimal configuration I could try to get the system powered on (only cpu installed for example)?

This is not my first system I built over the years, but currently I'm out of ideas.

Thank you, all.

	the obvious first, have connected the case power button? try to short pins with screwdriver to power up. on a old case my power-button failed one time. i think you will need MoBo+CPU+RAM+GPU to test. connect a pc speaker maybe for beep error codes?

	Power button is/was connected. I completely built it into the case, ready to close up (I know, I should have known better and test everything outside first :)) so the first thing I double checked after the thing didn't power on were all connections (graphics, quick wiggle on the RAM, all case connectors, ..). After this didn't help, I started ripping things out / disconnecting things again. In the meantime I upgraded the bios on my wifes Ryzen Mainboard and confirmed that the CPU and the RAM are working in her machine. While on that, I put her 1600 Ryzen into my board and her RAM also. Still not booting. (In this configuration I also tried shorting the pins cause it was a flying setup on the table and the cases power button cable was to short.) I'm currently pretty convinced that my board is dead. Except I have missed something crucial. I ordered an ASUS and will try again tonight. Thank you, for your input.

	Quick update on this. I switched to an ASUS PRIME X470-PRO. Plugged everything in. Booted on first try.
