Does the New Build fail to start when a PCIe card is not connected?
Does the New Build fail to start when a PCIe card is not connected?
Hi everyone,
I've just assembled a new PC and encountered a tricky issue:
After installing my RME MADI FX PCIe card, the system won't boot.
When I press the power button, the PWR-LED lights up briefly, the CPU fan spins for a moment, but then nothing happens.
To get the PC to start again, I have to remove the card, unplug it for a while, reconnect, and then it boots.
I've tried several things:
- Updating the BIOS
- Checking cables
- Reseating memory
- Using a different PCI-e slot
- Testing the card on another computer, which worked fine
My current specs are: AMD Ryzen 5 7600 at 3.8 GHz with a 500-watt PSU.
I suspect the power supply might be insufficient, and adding this PCIe card could overload it.
The RME card itself doesn’t seem to draw excessive power compared to a GPU, but I’m not sure if that’s enough.
Anyone have ideas or suggestions before I completely dismantle the PC and try another model?
Thanks!
My CPU runs an AMD Ryzen 5 7600 at 3.8 ghz, paired with a 500 watt power supply. When sharing troubleshooting threads, it's important to provide complete system details. List your specifications clearly as follows:

CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the PSU age along with its make and model. Also, note the BIOS version for your motherboard at this time.

Which slot is the card being installed in?
Moved thread from Motherboards to Systems.
I think the BIOS isn't recognizing which version of PCI Express the card uses. The RMI WADI EX site mentions: "1-Lane PCI Express Endpoint device (no PCI Express to PCI Bridge), revision 1.1". Verify your BIOS settings and try limiting the PCIe x1 slots to slower speeds. If the default is PCIe Gen 4 but your card only supports Gen 1.1, it could cause a conflict. Adjusting the slot to Gen.2 for the card might resolve the issue.
Thanks, the suggestion was helpful. I configured all four PCI-e ports in the BIOS to Gen 2, but the issue still exists. I thought PCI'e would always be backward compatible, so it should work in theory! My setup includes: Windows 11 Home, AMD Ryzen 5 7600 (3.8 ghz), Asus B650 Plus Wi-Fi, Kingston FURY 32 GB DDR5-6000 Kit, and a SAMSUNG 990 PRO 1 TB SSD, along with a Noctua NH-D15. Any other ideas?
I found the issue: I replaced the 500w PSU with an 850w Be Quiet! one, and then the PC started booting up.
That's strange! I looked it up and others said 500w should be sufficient for this CPU/MOBO setup without a GPU card.
