Frequently Asked Questions
Q: Is this M.2 to SFF8643 adapter compatible with both PCIe 3.0 and PCIe 4.0 M.2 SSDs?
A: Yes! The PH49-M2 adapter card supports both PCIe Gen 3.0 and Gen 4.0 M.2 NGFF M-Key slots running at X4, X8, or X16 lane configurations, making it compatible with a wide range of modern NVMe SSDs and motherboards.
Q: What size M.2 SSD does this adapter support?
A: This adapter is designed for the standard 2280 M.2 form factor (22mm wide × 80mm long), which is the most common M.2 SSD size on the market.
Q: Does this card require additional power or drivers?
A: No external power connector is required — the card draws power through the PCIe slot. It functions as a passive convert adapter, so no additional drivers are needed; your operating system will recognize the connected SSD as usual.
Q: Can I use this adapter to connect a U.2 SSD to my M.2 slot?
A: Yes. The SFF-8639 output port on this card is the standard U.2 interface, so you can use a U.2 SSD in systems that only have an M.2 PCIe slot available, effectively bridging the two interface standards.
