Need help troubleshooting new rig!

When I power on, some lights on the mobo light up. But nothing else. No fans, pump, etc.

I have nothing plugged into the cpu fan spot on the mobo. Is this where I should plug the pump? I assumed I could override this in the BIOS, but I don't get there.

Everything is new, except the gpu.
 
Do they stay lit up, or does it goes off in a few seconds? If you think the issue might be not having anything attached to the CPU fan header, through a misc fan on there and see what happens.
 
My recent sour experience with an AMD Asus board went a little something like this: Plug 80mm fan into chassis (rear side) fan slot and board (appears to have) died. Unplug and it comes to life again, without power cycling. :-/ I barely was able to catch the bios reporting the fan speed somewhere in the millions before it played possum...and that's when I snipped the yellow tach wire on that fan. ;-)

Had me chasing that for a full 14-16 hours over the course of 4 days, because those fancy lights on the MB was telling me I had no boot device.

I doubt that's your issue, as my fans were at least spinning (I think), just wasn't getting into BIOS or getting video when it played possum. But it's something to remember, one of the oddest incompatibilities I've ever seen.

Only took me three of the same motherboard to determine it wasn't the board! (Thank the good Lord Amazon is lenient)

Good Luck!

I have all fans connected to the mobo. The lights (start button, reset button, thumbdrive in usb slot) stay on. I can get a recycle by pressing the BIOS reset button.

It's good to know about the fan incompatibilities.

I'm brewing a large pot of coffee and searching for a paper-clip and my VOM, preparing for a systematic evaluation of the PSU. I will also step through all the fans to see if one (or more) mobo slot is the culprit.

Thanks, guys. Stay tuned.
 
I'm sure it has that new fangled USB BIOS update system, where you plug in the thumb drive, power up and hold down the update switch and things start flashing (both as in BIOS and as in LEDs on the board). As odd as it seems, your brand new board may have an old BIOS that doesn't recognize the top of the line chip.

I don't get any error LEDs. However, I used my Antec PSU tester and it indicated a fault. I will verify this with the VOM.

It looks like the lights that do show are not 12v, so I might have a dead rail. EDIT: or dead cable, so I still need to find a paper-clip.

I believe you need the pump plugged in the cpu fan spot. I was mucking around on a new build some time back and I accidentally unplugged the cpu fan and the rig shut down immediately.

I have found that too. Some BIOSs let you over-ride that. I had the fans to the radiator plugged there initially.

I unplugged everything and tested the PSU and found no 12v, so when I replace the PSU, I will plug the pump into CPU fan.
