Question Can't connect more than 4 sata devices

[msdesignfoto]

Hello!

I have an issue with my computer. Currently, there are 4 sata hard drives installed + 1 M.2 NVMe. The whole set work nice without issues. Now, I added an USB PCIe card and it requires SATA power. I plugged the wires but USB devices plugged in the PCIe card do not work well.

Current motherboard is an Asus Prime H610M-K D4 with an Intel i5 12400F.

But before this set, however, I had a Gigabyte motherboard with an AMD 6350 Six-core CPU and there was also this issue, altough with a different number of sata devices. I installed an expansion bay for sata hard drives and it also doesn't work. If I would unplug one hard drive, whatever it is, the drive bay will work and read the inserted hard drive.

Likewise, if I unplug one hard drive with my current setup and plug an USB device into the PCIe card, or a hard drive into that bay I still have installed, they will work. If I unplug two hard drives, both the sata bay and USB through PCIe devices will work.

Lack of power? My PSU is 850W. My previous PSU was 650W and I upgraded it precisely for this issue, yet it still happens.

Motherboard was changed.
Power cables were changed.
PSU was changed.

Any explanation for this?

I rectified the original post to reflect this.

Current PSU is a Nox Urano TX 850W. But the issue also used to happen with my previous setup, that had a Mars Gaming MPII 650W PSU. So I'm assuming the PSU is not the culprit.
