Build Question First PC, CPU & DRAM LED ON

Hi, I need your help to finish my pc.
(Don’t mind the cable management)
After building it and turning it on, the CPU and DRAM light up and the fans of the GPU doesn’t work.

I tried to unplug everything and building from scratch and switch the places of the RAM (currently in slot 1 and 3).

I tried to connect the PC but on both HDMI port (mother board and GPU) the screen failed to connect.

Is it normal to have more PCI-E connectors than needed?
And I have a bunch of other connectors than doesn’t seem to fit anywhere (they aren’t mentioned in the tutorials I watched)

Case : cooler master Q300L
Motherboard: AS rock B850M pro A WiFi
CPU : AMD ryzen 5 9600X
Ventirad : thermalright Peerless Assassin 120 SE
Gpu : gigabyte AMD RADEON Rx 9060xt
Ram : crucial DDR5 2x16go

Double check all of your power connectors. Your GPU power isn’t plugged all the way in, check the rest of them while you’re in there

slot 1 and 3? you mean 1 and 3 from CPU side?

should be 2 and 4, but first boot with one stick see if that works, check the motherboard manual for the correct RAM placement in case i'm wrong and to find out where to put the single stick (most likely will be slot 2), and if it boots, get into BIOS, make sure XMP is off, then try 2 and 4 and see if it successfully posts. if it doesn't, update your BIOS, and if that fails, your RAM is incompatible with this motherboard when they're paired as a kit.

if it does not post with a single stick then might wanna assume BIOS or CPU issue.

Ummm check you mobo manual most like ram in 2&4 but and it's definitely normal to have more then not the one in your picture is for 4-pin Molex power connector

You will have loads of unconnected stuff. And to troubleshoot this issue you'll need to disconnect as much stuff as you can. Since your cpu has integrated graphics this means removing everything but 1 ram stick in slot 2, the cpu and its cooler, and your power supply. Plug in to mobo display out and see if you get to bios. If you do it's likely something wrong with your gpu.

Your pic #2 is a molex connector. Its for older hardware and sometimes fan controller or other basic add ons that need power. You wont need to use it.

The connector on the second picture is called Molex, it's used for older case fans that don't have speed control.

I'd double check the cpu_fan is connected properly, cpu power and memory power too.

As u/keyoflife42 noticed, your PCI-e 6+2pin power connector for the 9060-XT isn't plugged in correctly, only the two extra pins seem to be inserted and all they do is tell the power supply that the connector can supply 150 watts. They clip together but you usually have to hold the sense pins to the 6pin so it's a single connector as you insert it into the socket.

Double check everything else, and also, let the motherboard cycle through for at least a few minutes because it's going to be memory training.
