ASUS Maximus X Hero not powering up

[Delnilas]

I’ll include a full parts list below. But the short version is, I have a STRIC 1080ti and both of their LEDs light when I hit the power switch on the psu. Both the case power button and the motherboards “start” button do nothing. The start button is lit red, if that matters. I assumed when I got my power supply years ago, it was a thermal power supply. As it worked fine, but the fan didn’t spin up when I tested it. So I can’t use th normal paper clip method. Help?

Try borrowing a power supply and testing.

Don’t have one. I have an ancient power supply that doesn’t even come close to the power requirements for the system, but I doubt it’d work.

Try testing with only CPU and CPU cooler installed. No other components/wires/fans. How old is the setup?

System was first built in June of 2015. I’ve had the psu since then, almost every other component is new. It’s worked fine with the 1080 it, but I recently got a new Ssd, cpu, and mobo.

I'd firstly try to rule out a faulty power supply and then go further. Try also clearing the CMOS (unplug the power cord and remove the CMOS battery for a minute).

Just pulled everything but the cpu and cooler, including RAM, nothing. How do I safely remove the cmos battery? I’ve tried clearing the cmos several times with the button on th board, but nothing. And I don’t want to damage it by remove it wrong.

If you've tested the button, then it's the same. Try borrowing a power supply. Or buy one and, if not working, you'd have a spare... Or, a local pc repair shop might help.

Just got back from Best Buy with a new power supply. Tested it same as before, nothing plugged in except for the cpu, cpu cooler, and mobo power. Nothing.

If removing the 8 pin power cable and connecting a case fan to the motherboard, does the fan spin when board started?

Before I test that. I have my AIO’s pump connector (3 pin) plugged into the 4pin AIO pump connector on the motherboard. I read online that this was safe, electrically, could that be causing any problems?

No, That port is designed for pumps. Higher amperage.

Just tested the fan - nothing. I’m assuming that means my motherboard is bad. Running out to the Microcenter to grab a replacement now.

Yes, it seems so. Try RMA-ing it. Test the new board withe the new power supply.

I’ll try with my older power supply first. I wasn’t able to find anything permanent at Best Buy, so unless there is potential for damaging the board if that psu is dead, I’ll just stick to that in hopes of not having to order another gold certified psu. That seem safe/logical to you?

 

[alexoiu]

Not sure what to say. It's an option.

Got the new motherboard installed, and everything is working great! Sending the old one back tomorrow, guess it was the problem after all. Thanks for all your help.

For nothing. Thank you for the update.
