The Killer Wireless-AC 1550 can be used in some M.2 to PCI-E converters, allowing desktop machines with open PCI-E slots to use the adapter, provided the following conditions are met.
- The Killer Wireless-AC 1550 can only be used in PCI-E 1x or PCI-E 4x slots. It cannot be used in the longer PCI-E 8x or PCI-E 16x slots. Using an incorrect PCI-E slot can cause the 1550 to either not appear in Device Manager, or to appear in Device Manager with an error, or a bang symbol.
- In our testing, we have noted that converters often do not produce working results when the converter is plugged into a northbridge slot. We advise that you use your converter in a southbridge slot. Although you will need to reference the technical specifications for your motherboard to know which slot corresponds with which bridge, southbridge slots are generally those beneath the dedicated graphics slot on a desktop motherboard when the motherboard is installed in a tower case.
- For Bluetooth, a USB cable must be run between a USB 2.0 header on the motherboard and the USB header on the converter. If this is not connected, Bluetooth will not appear in Device Manager at all, and will not be usable.
- We cannot recommend any specific PCI-E converters. These are usually available from various vendors on Amazon, and most of them seem to work well, but they are typically unbranded, so buy at your own risk.
- Please note that the Killer Wireless-AC 1550 is only compatible with Windows 10.
