[SOLVED] PC turning on, but no output on monitor

[Memeboibeep]

I have recently built my first PC, all lights and fans are on, but the monitor only displays: "No HDMI signal detected", but it does detect the computer

The CPU (AMD 2600x) is in correctly.
The RAM is in as well.
I think the graphics card (Radeon RX 580) is in correctly, though there is a white LED on.
All PSU (Corsair RM650i) cables are connected.
The HDMI is plugged into the correct slot on the graphics card.
My motherboard is ASUS Rog strix B450-f, if that is useful.

Any help is welcome!

Can you take a picture of the inside of the pc so we can take a look and make sure everything is in place?

Top left of the motherboard, you're missing the 8pin EPS 12v power cable

Oh thanks let me try

 

[Memeboibeep]

This is what powers the cpu. Everything else from what I can see does look correct. So it should fire up once you plug that in

Ah that would make sense. Trying to find the cable now!

Edit: I cant find it what does it look like?

Can you send me an image pls I cant find it

 

[Memeboibeep]

This.

Make sure it's the CPU and not PCI-E cable you plug into it.

I meant the cable, sorry I wasnt very clear.

It'll probably have "CPU" written on the side of the connector.

Ok I've found it. The end labelled "Type-4" fits in that slot, but the "CPU" end doesn't seem to fit in anywhere.

 

[Memeboibeep]

Any joy?

Found cpu cable but it doesnt fit in psu. The end labelled type 4 fits in the motherboard though.

Have you tried the other end into the PSU? I think one end should have 2x 4 pin blocks together and the other end should be a solid 8 pins, the solid end should go into the PSU.

Wait no it does

It works. Thanks so much!
