What PCIe-to-NVMe adapter works well with a B550-F and a raised heatsink?
Asked by

I have an ASUS B550-F motherboard and want to add another NVMe drive using a PCIe expansion card. Ideally, the adapter should position the M.2 drive high enough to leave room for an aftermarket heatsink, and it should support a double-sided 2280 SSD if possible. My existing 1TB PCIe 3.0 Kingston drive is nearly full, while my 4TB WD Black SN850X is about half full. I'm considering another SN850X or a newer SN7100, but I'd like to avoid upgrading my AM4 system to AM5 and DDR5. Has anyone used a reliable adapter that offers good cooling clearance?

The motherboard already has two onboard M.2 slots, so the expansion card should go in the lower full-length PCIe slot. The shorter slots only provide PCIe 3.0 x1, which would severely limit an NVMe drive’s performance.

Most basic PCIe-to-NVMe cards are just passive adapters that route the PCIe lanes through, so there isn’t much electronics to fail. Look for one with a proper M.2 mounting screw and enough clearance for your drive. The SN7100 and SN850X generally don’t require a huge heatsink as long as the case has reasonable airflow.

I used a JEYI M.2 PCIe adapter with an aluminum heatsink and had a good experience testing it. It supports PCIe 4.0 x4 and common M-key drive lengths, including 2280. A similar raised adapter with a clip-on heatsink should meet your requirements.

MellowQuartz47: The main thing I’m still trying to confirm is whether the adapter and heatsink leave enough clearance for a double-sided SSD. I’ll check the card’s spacing and the drive thickness before ordering.
