Before You Decide
Check that your motherboard has a free PCIe x4, x8 or x16 slot, and confirm that your case suits the included low-profile bracket if needed. Also make sure you want dual USB-A ports rather than another connector format. If your build uses an x1 slot, this card is not the right fit.
