need help with a Maximus Z790 Hero

Level 7

Just got a ROG MAXIMUS Z790 HERO and was blown away by the level of wires and connectors and such. Problom is I finally got it all set up and well... looks like the powers on but no ones home?

The RGB lights on the MB and the RAM start but nothing else starts, not even any of the fans. No picture or anything from the monitor ether, monitor acts like nothings even trying to reach it.

Here is pictures of the set up and its my first time dealing with this level of
wires and connectors. From what I can tell everything should be hooked up right. Read the booklet to make sure I connected everything right. All the power plugs however are VGA (To the three ATX power slots on the MB) but the booklet never said any of them used the CPU power connector.


The GPU also doesn't light up nor get power.

Sounds like a power issue, so double check all leads at the motherboard and PSU. If your PSU is modular, some connectors could have got pulled out slightly when setting up. 

The 24 pin motherboard connector can be really difficult to get fully seated, so support the motherboard from underneath when you push it in.  You should also have connected both 8 pin power connectors to the motherboard (top left), those are for CPU power and are usually labelled as such. Usually the labelling will be something like CPU1 and CPU2 on the power supply. Make sure there are no gaps between any of the the power plugs and sockets when seated. DO NOT connect the PCIe (VGA) leads to the motherboard. They must be the CPU ones. From what you say, I wonder if you've not done that correctly. 

The PCIe power leads (might be labelled as VGA) will go to the GPU - not sure how many you need for your GPU, but can be up to three. These are often 6+2 pin power connectors. How you connect those will depend on your GPU.

Dear JohnAb!
the owner of such a config is called a professional barbarian.
I don't want to hurt anyone, but to be honest, I have never seen such a valuable configuration, put together in such a way.

cable management is a big zero

Certainly some opportunity for tidying up... 😀

To be honest , i can't see anything from the picture , but careful to fully plug as mentionned , the 24Pin AND Cpu cable both on motherboard + PSU.

I've changed for custom cable 3 days ago , and got this surprise too.

This is what it looks like for me now :
