I just finished my new build but it is not powering up. The lights are on on the motherboard showing power to the on button and the reset button is green. There is no error messages or codes. When I press the on button, nothing happens. The fans do no spin and the LEDs do not switch on either for the fans. I have checked the sockets and they appear to be fully wired up correctly. The PSU has the pin inserted to turn it into one rail as the MB require it to be run off one rail. I have only inserted one stick of RAM into the slot. Surely the fans would switch on and lights would power up too?
Asus WRX90e Sage Motherboard
AMD Threadripper pro 7975wx
Corsair I170I Elite

I flashed the bios and no luck. I even removed the cpu and hit the on button but it still doesn’t turn on. I am so confused. I have tried this with two different boards and I can’t believe they are both broken. I have used the PSU in another computer and it worked.
Any suggestions would well received. I have no idea what is not working.
What I would do, based on getting mine to work.
Tr6 has to be tighter than tr4 so the old torx wrench might not get it secure.
Install a cooler and two sticks of ram in the correct first two slots and push both sides really hard. They are too slim and it’s really difficult to get them seated properly.
Install a gpu with one monitor on the hdmi port only
Disable the on board vga switch.
Check all switches are on the default position
Try a proper single rail psu. These motherboard are very temperamental to power, blew my 1600w superflower.
Been fine since i replaced the psu.
My guess is the psu.
I have an extremely similar setup (same: mobo, CPU, PSU; different RAM, AIO cooler). Your description matches the same config that worked fine for me, including the PSU jumper to single rail and the locations of the PSU cables to CPU_12V(1)_1 and CPU_12V(2)_1. I agree that your system should work based on what you describe, but I want to avoid making assumptions about the unmentioned items:
You do not mention GPUs or NVMe and no GPU is pictured:
If you have no GPU, then install one, use HDMI (not DisplayPort) into the GPU, and let us know if you can get to BIOS. The CPU does not have an iGPU, so the display ports on the mobo will not work without a dedicated GPU.
If you have multiple GPUs, the mobo may need more power (PCIE_CPU_12V_1 and PCIE_CPU_12V_2). In my similar build, I needed to use the cross-over cables that came with the mobo. Attached below is a page from the manual + annotations with more info.
Also, just in case: Here is a link to more details about my installation – although the post is mostly about getting 5 GPUs to work on that mobo+CPU setup
I don’t have a gpu installed. I have a Corsair RMX 850 psu which should be a single rail psu . It should be enough to power Motherboard and CPU.
No nvme installed. 1 ram from the qvl list in slot A.
Connected the psu in 5 places 24 pin atx 2 8 pin cpu and 2 8 pin pcie. Only the connectors; that were covered and are intended for dual psu, are not connected.
When I turn on the psu the power button lights up red and the reset button green.
When I push the power button nothing happens no fans spin the q code display remains dark. No other leds are on.
I would think even without ram and cpu I should be able to get a q code or q led.
Is there any difference in behavior if you immediate try to boot the motherboard after flipping the PSU switch to on?
Doing this might rule out the 5vsb rail becoming overloaded.
Do you know what the minimum requirement is to get a code?
I want to rule out a faulty cpu. I am thinking if the cpu was faulty or not seated right I would still get a q code or at least a q led.
I built my system recently with the exact same motherboard, though my system POSTed on first try.
My system has these following critical components:
AMD Ryzen Threadripper PRO 7965WX
Silverstone XE360-TR5
Kingston FURY Renegade Pro KF556R28RBE2K8-256
ASUS ROG Thor 1600W Titanium
Nvidia GeForce RTX 4090
Nvidia GeForce GTX 1080
I mention the graphics cards because they were installed at the time of boot, and I’m wondering if installing any GPU into the first slot for display-out would help with the POST, just to see if it behaves differently. If not, it could be that your motherboard is broken or your PSU cables on either end are not fully seated as they should be. If either of those don’t resolve your issue, then it could be that your CPU is dead or you didn’t install it properly.
I would check the CPU installation first. Uninstall it, and inspect the socket for any bent or broken pins. Make sure you use the Threadripper screwdriver that is included with the CPU, and not any older Threadripper screwdriver.
If it looks okay (and you will unfortunately have to reapply the thermal paste on the CPU and wipe off any that was on your cooler), I would check the power connections. Either something is missing, not seated properly, or connected to the wrong thing. Your motherboard is certainly receiving power if the power button and reset button are on, but perhaps it’s just not receiving enough power to actually boot? Check all your power connections, including your fans to the headers.
Worst case scenario, I would buy another motherboard (the same model or some other one) and try the same thing in that board just to confirm your CPU isn’t dead and your RAM and PSU works fine. If it works then, it is likely that your current motherboard is dead. I would return it if I were you since you would a. already have a working motherboard and b. not worth the RMA hassle.
I think the CPU not being seated properly would cause the system to not boot at all, yes. If you have checked everything else, then it must come down to either the CPU being installed improperly (or being dead), or something is wrong with the motherboard (which I doubt since it appears to receive power).
Thank you so much. Looking into the cpu a bit more I realized I got scammed. The cpu I bought is a 59xx or 39xx model with a 7975 heat spreader. Really messed up situation.
It actually bent the pins on the socket a little but it should be ok still. Getting a new CPU.
That’s outrageous, and I’m sorry you got scammed. Though it certainly would explain your computer not booting at all.
What to Expect When You Press the Power Button
When you press the power button, the following should happen all at the same time (I paid attention to my PC when I booted it up today):
The case fans start spinning and ramping up.
The GPU fans start spinning and ramping up. (If your GPU has any LEDs or lighting elements, it might take a few seconds for them to turn on.)
The Q-Code panel should turn on immediately.
I also think the debug LEDs should turn on but I don’t remember. However, they will be activated as your PC goes through POST, so if that happens that’s expected behavior. You should expect them to turn on and then off in sequence as your CPU checks each component. If they turn all off, that’s good, and you should just let it continue.
Sorry you were scammed; hopefully you can get Ebay to refund you the money and buy it somewhere else, like Microcenter if you have one nearby or Amazon.
For anyone else looking, my wrx90 often won’t post until I press escape and enter.
I think it’s booting into bios but not displaying it.
I need to switch the on board vga on to test, or learn how to use the ipmi…
Sometimes f1 works, because there is an f1 wait in the bios somewhere as well.
Sometimes it boots just to hdmi or just Displayport.
It is currently AA on the error code but no display anywhere.
Worst motherboard I’ve ever had
