Not able to use SATA expander chip

Hey everyone

I recently built a custom PC with MSI B560M PRO-E motherboard which has 4 SATA ports and 1 NVME M.2 SSD port.

However, I have 6 hard drives and 1 SATA SSD which had to be attached to this system. So, my build was dependent on a SATA expander chip (Waveshare M.2 NGFF SATA to 5-Ch SATA3 Expander, JMB575 control chip).

The plan was to use 3 SATA ports on the motherboard for the SSD and 2 hard drives. The motherboard disables 4th SATA port when you attach something in the M.2 slot. Then I would attach the SATA expansion chip in the M.2 slot and connect the remaining drives to that chip.

I'm using the Corsair 450w power supply which supports 7 SATA connections and all the drives are plugged in.

Now, the problem I'm facing is that the motherboard data sheet clearly specifies that the motherboard supports SATA on M.2 slot. However, when I plug in the control chip with the hard drives, they are not getting detected. The BIOS clearly says that nothing is attached to the M.2 slot.

So, my question to the readers here is, how can I plug in all 7 drives to my system. Do I need a different M.2 control chip OR is there a way to split SATA connections so that I can plug in all the drives.

Thanking you all in advance

In order to use the adapter you purchased for m.2 your motherboard not only needs to support SATA (which this does) through the m.2 slot, it also needs to support SATA PM (port multiplier). This is a separate standard than just plain SATA. I suspect your board does not. Or if it does, it needs to be enabled in the BIOS.

The other option you can use here is to put a SATA expansion card in one of your two PCIe slots. But perhaps you already have something in those. In which case, the only other option at that point would be to start connecting via USB instead. You can do this internally via an adapter, but you are limited to the speed of whatever USB connector you’re tapping into. Same applies for external.

Otherwise you’ll need a motherboard with more SATA support, or SATA PM.
