On New Ryzen build can't see the monitor on startup

[almand]

Hey,
I build a pc with ASUS b350 plus, Ryzen 1800x, Crucial Ballistix Sport LT Red 16GB and I'm stuck. Plugging on monitor for the first time doesn't give me the bios or anything else onto monitor.
I noticed as well that switching the PSU onto Input selection starts automatically the pc (which it's not normal, since the PC should start with on case button.)
Please enlight me what is wrong, sinse all 4 fans and systems leds work properly, except monitor signal (graphic card Gigabyte GeForce GT 1030 and Netzteil 750 Watt CP 750W Plus aktiv PFC ATX PC.
Thank you in advance

Hi, If leaving only CPU and CPU cooler installed, both 24 and 8 pin power cables connected (no other wires or components), same automatic start?

I suppose the suggestion was about the PSU issue. So, stepping backward I unplugged one by one almost all components (graphic card, SSD, memory, etc) but the problem was still there. For a while I managed to have a Input ON and mb standby idle PC, but plunging Cooler's cable the PSU starts again working without on case button. So I'm stuck again. The post was helpful in order to find out where to focus, and that is cooler's connections on splitter. So I'll try to see a video with the Cooler Master ML120L RGB Water Cooling installation in order to find out what is wrong with these connections. Thanks again.

No problem. Can you test different power supply?

 

[almand]

I've already done. (It was my first option). Both were 750W and work. Correct me if I'm wrong but at present I'm focusing on Coolers connections

 

[alexoiu]

How have you connected the cooler (radiator fans and pump)?

 

[almand]

According the manual but it's not that clear, that's why I try the connections to find the right one

 

[almand]

What buttered me is the fact that fan and pump have 3-pins connector and the mb a 4-pin. (And no colors since the cable is covered)

 

[alexoiu]

Can you post a picture of the pump connection on the motherboard? And, again, what headers on the board have you used for connecting pump and fans?\

 

[almand]

Sorry, but how to do that? I'm new and I don't know howto post a picture

I upload 3 pictures. Cooler's diagram and connections on Chas Fan and CPU fan. I didn't used the splitter since I didn't solve the PSU issue yet

It looks ok. Do you have the original AMD CPU cooler?

 

[almand]

No cause it's AMD 1800x and not 1700 ryzen

 

[alexoiu]

I'd try testing the board outside the case. If still no go, I'd return the motherboard, if under warranty.

 

[almand]

Finally the MB wasn't stable, and the shop is going to send me a new one since it was under warranty. I tighten gently the screws on board and I manage to see Bios and make the update. The MB worked properly if no one touch it but not stable. Thank you for your help.

You're welcome.
