Very good product but incompatible with my Dell case
This product is very well finished and offers an interesting solution to keep an old asus xonar essence pci sound card going! (excellent audiophile sound card) but I turned the sound card and the pcie to pci adapter every which way in my dell pro max t2 case, impossible to fit all that in without having to cut the case panel. So I’m giving up and trying to find an external audiophile usb sound card!

At last, an adapter that works
This is the third PCIE>PCI adapter I've tested, and on my configuration (AMD, X670E chipset), this is the only one that works perfectly. I plugged in an old sound card and had no problems whatsoever: playback, recording, RÀS, everything was in place. Based on a Pericom PI7C9X118SL bridge, it gives better results for me than other models based on a PI7C9X111SL (no detection on AM5) or a PLX PEX8112 (detection but erratic behaviour of the sound card).
Of course, this raises the card's profile in your case. To get round this problem, I opted for a PCIE 1x riser and attached the card and adapter to a vertical slot, which is included in some cases.
Also, be careful: as the PCI and PCIE voltages are different, the adapter supplies your PCI cards via a Molex connector. Make sure that your power supply has such a cable (this is no longer systematic).
