Orange motherboard light turning on during startup, but no other activity?
I have an orange light on my Asus Prime B550M-A WiFi II motherboard. After the orange light, no other activity occurs. I’m not sure if I’ve connected the power connectors properly, so I’ve shared photos below. The RAM is correctly installed, the power supply looks fine, and I’ve connected the CPU fan, but nothing seems to be working. It isn’t booting up, the CPU fan doesn’t spin, and the graphics card fans also aren’t running. Just an orange light.

[Edit]
These are my device specifications:
I verified compatibility with PC Part Picker; all parts are new and brand new.
PSU: Corsair RM850E, fully modular ATX power supply. Only used cables came with the PSU – one 24-pin cable to the motherboard’s 24-pin slot, a PCIe cable from the graphics card to the PSU, and then the CPU cable back to the motherboard and finally to the PSU.
No disk drives are used; I have two 16GB DDR4 3200 RAM sticks, a Force Vulcan Z SSD (Samsung 970 EVO Plus 1 TB PCIe NVMe M.2), and a computer case with a fractal focus design.
Motherboard: I have a guide with step-by-step installation instructions and a DVD disc, but I can’t find the booklet that came with it.
I’m also connecting the PC to a monitor using only HDMI, which means both devices have separate power cables.

I looked at the PSU cabling and tightened it a bit more. Now everything is spinning properly. The main problem is that the case fans aren’t working, because my motherboard only has 4-pin connectors. I’ve installed both fans, but one fan light is on but not spinning, and the other doesn’t light up at all.
Ensure you have identified the right User Guide or manual.
Review the instructions thoroughly, confirming all connections are properly positioned and securely attached.
Check cards, RAM, jumpers, and case links as well.
Chapter 1 contains detailed information about connections and pins; fans are listed on pages 1-2.
Identify the correct 3-pin fan model installed.
Also verify the relevant configuration settings to match your motherboard and components.
Pay close attention to all details and warnings in the manual.
If needed, consult the official Asus website for the latest updates.
It’s easy to make mistakes with cable connections—just because a cable fits somewhere doesn’t guarantee correct pinouts.
Avoid altering connections without confirming they align with the motherboard and component manuals.
Go through the guide carefully, take notes, and report any discrepancies.
