Morning all. Its been a long day. Started my first build today to find it looks like I have no power on my MB. I can press the power button and fans kick in but nothing from the MB. I removed everything and tried a bios update following the instructions from the Asus Website. However its doesn't seem to want to run from the USB. I checked the wiring loom from the PSU to the MB to find a cable was connected PSU end, but the cable was missing from the MB. It looks like its never been terminated, there just isn't a cable there. Do you think this is the problem or is it something else? The cable that is missing is pin 20.
Asus TUF Gaming 650M Plus Issues
- Thread starter Abacus614
- Start date
So to up date, as I didn't mention this last night. With everything plugged in the power button does nothing. It's only when I remove the 8 pin ATX, the power button will power up fans and GPU. If that helps

Edit: sorry, just noticed this is a first build, so I assume it never worked?
What happens with it plugged in, is not expected behaviour.
It could mean that there's a problem in the VRM/CPU area, since I assume that's primarily what it supplies, but that's just an uninformed assumption about how these things work.
You could check the cooler mount and look for damage around the VRM/mosfets.
That's unlikely to be an issue, since missing wires is not uncommon and I expect it worked previously without it. That said, I don't have access to Gigabyte's pinout, so I can't say for certain. You could check in reviews, though you'd need high resolution photos of the cables to notice that.

So i cleared the CMOS
I appear to have sorted the power issue. And I now have power on the MB, however the ram led is lit. I've trouble shooted following the instructions on the Asus website to no avail.
I've removed the ram and I still can't get onto the splash screen. I've cleared the CMOS and tired to do a bios flash. But it just doesn't seems to want to read the usb. I've tried a few and still no joy.
Thanks for your reply.

So an update on this.
I cleared the cmos again and found that removing a stick of ram I final got it to post. For some reason it won't post with a stick in A2. I now have both sticks in B1 and B2. It posts and I can see both sticks in the bios. Which I finally managed to update by the way.
Any ideas why it won't ost when the ram is in the correct configuration of A2 and B2?

I'd say the most common reasons are:
1. Stick is not seated correctly.
2. Cooler mount is uneven/too tight/too loose.
3. Bent pin in socket.
If it is uneven it can change contact pressure between the CPU and the socket, with losing a memory channel one outcome of that.
Ahh, i see. Yes that makes sense. I'll have a look at that.
