I assembled a new PC with these specifications:
Motherboard: B650E Steel Legend
CPU: R5 7600
RAM: 2x16GB F5-6000J3040F16GX2-RS5K
PSU: RM850e
GPU: 6700XT
Upon powering it on, there was no display and the CPU & DRAM LEDs were solid red with blinking red lights. I left the system idle for 15 minutes without any changes.
Please note that I'm not using the PSU power cable that came with the RM850e because it doesn't fit into any of my wall sockets. Instead, I'm using an older PSU's (VS450) power cable. I hope this isn't the cause of these problems.
I've tried the following steps so far:
- Reseated CPU and RAM
- Booted with only one RAM stick in all slots, then repeated with the other stick
- Disconnected GPU and connected HDMI to the iGPU
- Reset BIOS by removing CMOS battery and reinserting it 5 minutes later
Could this be due to faulty RAM, a bad CPU, or could the motherboard be defective?
I'm completely stuck at the moment, so any advice on how to proceed would be greatly appreciated. Thank you.

Ensure rams are in slots A2 and B2. Check the CP{U} socket for any bent or broken pins. What method are you using to cool the processor?

did you ensure all power cables are connected to both the PSU and the motherboard? there should be at least three for the motherboard and CPU to be plugged in. main 1 upper left 8pin connector, the large one with 18pins on the right, and the CPU 8pin connector. https://assets.corsair.com/image/up...-r...0e-03.webp update to the newest BIOS using flashback feature

The RAMs were located in the A2 and B2 slots. Once it didn't POST with that setup, I tested each slot one by one using all the sticks. Nothing changed.

I'm running the Stock cooler that comes with the 7600.

I don't have access to another case.

This RAM package was shown on the motherboard's Memory QVL.

Unfortunately, I don't have it.

Consider leaving the CMOS battery disconnected for at least two hours or overnight. This method successfully reset the CMOS on my setup. Unless you’re familiar with shorting the CMOS jumper pins, refer to your motherboard manual for guidance.

Switch the CMOS battery out.
Update your BIOS—this might fix the CPU and RAM not being recognized by the board, which causes the red blinking lights. Many manufacturers advise updating the BIOS before adding hardware to ensure proper recognition. Once updated, continue with the rest of your installation.

Reset the CMOS using the jumper pins or remove the battery, then take out your RX 6700XT card and plug in the video cable to the onboard video port (IGPU). Launch the computer and check if the boot splash screen appears with BIOS options.

You may need another machine to obtain the latest BIOS for your motherboard. If unsure about updating the BIOS, ask for help here—experienced users can assist with your setup. Good luck resolving this issue, and thank you for your patience.

Yes, I've linked the 24-pin motherboard with the two 8-pin CPU power cables to both the PSU and the motherboard. I'll test it out.

There's a jumper at the bottom of the board in the center for resetting CMOS just use that rather than messing around with the battery.
The manual for the motherboard just seems to indicate that red lights indicate failure and says nothing about blinking. Generally speaking with lights like that it's whatever the last thing that comes on which is the issue. Of course the problem is that this doesn't rule out the motherboard or CPU being the issue when it comes to DRAM since the slots could be the issue or the CPU memory controller. Unfortunately things like this really do require swapping parts.

After several attempts, it appears to start now. The confusion comes from not making any other changes ('except attaching the chassis speaker header this time to hear the beeps) and it booted after two minutes. Thank you everyone for sharing your troubleshooting tips!

Thank you for the instructions regarding the jumper pins. It seems the individual encountered issues with their computer not starting, but their tips helped them personally with past gaming setups. Cheers.
