Fresh build, no power

Hi there, yet another first build struggle.

https://pcpartpicker.com/list/2tyCYT

LED on vid card and one LED on mb turn on, nothing else, no front case indicators, no fans, no signal to monitor.

What I have tried:

Reseated every power connection, all RAM, vid card, and cpu.

Cursing.

Thanks in advance for thoughts, headed back into the checking and rechecking.

So, by "no power," do you mean there is absolutely no activity on the computer? Try these three things:

1) I see in your list that your PSU is modular. Double-check that the ends of the cables are connected to its correct side.

2) Unplug/ take out the wi-fi adapter from the motherboard and try to power it up. Just in case. Those adapters could sometimes go haywire.

3) Try a different power supply. I know this one MAY NOT be possible if you don't have a spare.

The only indicators of life are the 2 LEDs, one on the vid card and one on the mb.

Power cables have all been checked.

WiFi adapter did not affect anything connected or disconnected.

I tested the psu with the basic fan check as described by the mfg, seems to be operating at a basic level at least.

I think I now need to find a way to test the mb/cpu?

It does seem to come down to either the CPU/MB, but I would still find a way to test the PSU. Even if lights do go on and the fan spins, it may not have a pleasant time trying to take a load, e.g. trying to turn on the computer.

If you can, temporarily short the power switch pins, could be a bad case power switch. You are already double checking the connections, re-check all case connections too (it's easy to get the power, reset, and LED connections messed up). if nothing else works, I'd say that the motherboard is the top suspect; the PSU seems to be working at least minimally but it would be suspect #2.

You did connect the separate CPU power cable, right?

Well, as sure as I was about the front panel connections, something must have been off... I started fresh and redid the whole panel and viola! We are installing software.

Thank you both so much for the time, I expect a lot of people find their solutions to infuriating problems here.
