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!

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

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.

It might be a 4+4 cable one end that goes to the motherboard with 8 pins that plugs into your PSU, older motherboards only used 4 pins instead of 8, so those connectors came in two halves that you just put together if you need 8 pins.
