Where to buy

The AXAGON PCEM2-1U internal adapter allows connecting an M.2 SSD disk to a desktop computer using a PCI-Express bus.

The well thought-out design and ultra compact size of the adapter allow using it easily in a desktop computer not equipped with an M.2 slot. The card is also ideal for a rack 1U server and low profile cases. Its unique design allows using it not only in x16 slots, but also in x4 and x8 slots.

The adapter supports the use of NVMe (PCI-Express) M.2 SSD disks, both one-sided and double-sided ones. The reduction does not have a limit of SSD disk capacities and M.2 cards with a size of up to 22x80 mm can be used. Due to the PCI-Express 3.0 4-lane interface rates of up to 8 GBps can be achieved.

The thermally conductive pads and coppered vents help to remove better heat generated during the operation of M.2 SSD disks. The LED indication indicates connection and data transfer.

• Bandwidth of the 4-Lane PCI-Express 3.0 bus of up to 8 GB/s (two-way).

• NGFF 75-pin M-key slot to install the NVMe (PCI-Express) M.2 SSDs.

Other features:
• Full Plug and Play support.
• Support of M.2 disks of size - 2230, 2242, 2260, 2280 mm.
• Support of M key or B+M key NVMe (PCI-Express) M.2 SSD disks without a maximum capacity limit.
• Support of both one-sided and double-sided M.2 disks.
• A better dissipation of heat due to coppered vents and thermally conductive pad.
• Support of booting from SSD card.
• Possibility of using in 1U rack servers.
• Dimensions: 90 x 22 x 5 mm, weight: 10 g.  
• No drivers need to be installed.

Power supply:

AXAGON M.2 SSD disk adapter is let say only HW connector change from M.2 into PCI-Express or SATA. Adapter itself do not have controller electronics and need no drivers. It is necessary to check M.2 disk driver availability for older OS like Windows 7.

Proper M.2 adapter function requires:
- computer mainboard support M.2 disks – SATA disks are more often supported than NVMe disks,
- computer mainboard support booting from PCI-Express bus – in case of OS installation to M.2 NVMe disk,  
- driver availability for M.2 SSD disk – apply especially for NVMe disks on Windows 7 OS.

Please contact the motherboard manufacturer's technical support to determine support for motherboard M.2 drives. In some cases updating the BIOS/UEFI is sufficient.
Check the M.2 SSD driver availability on the manufacturer's website or contact the disk manufacturer's technical support.

The disks connected to the SATA motherboard controller are usually displayed In BIOS/UEFI. The NVMe disk is usually displayed in the "Disk Boot Order" menu.
This applies when the requirements of "Prerequisites for proper M.2 function" are met.

A): If the PC does not run with the card or the card is mistakenly detected in “Device Manager”, or if there is a yellow exclamation mark on the driver, or if “Device Manager” reports an error code “Code 10 - The device cannot start”, the card is in conflict with another device in your computer.

B): In most cases, this conflict can be solved by moving the card to another PCI (PCIe) slot, with the BIOS assigning other free resources to the card. If the move does not help, try the card separately, with no additional cards inserted. If the card cannot be moved to another slot, you can reset the BIOS of the computer (by jumper on the board or pulling out the backup battery, we recommend that you note all the original settings and reset everything to the required values). This will cause the IRQ, DMA, and I/O resources to be redistributed.

A): By initializing the disk, you can set the mode in which the hard disk will work

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

A): The newly purchased disk must be initialized before first use.

B): If the new disk is not initialized automatically, open "Disk Management", right-click on the desired disk and initialize it.
