It varies by motherboard design. Which one do you own? The 90 series were among the first mainstream boards with M.2 support, meaning a Z97 with an M.2 slot works fine. If you're thinking about attaching an M.2 drive via PCIe to a system lacking an M.2 port, the short answer is likely "no," though the key factor is the motherboard itself, not the processor.
It varies by motherboard. Which one do you own and does it include an M.2 port? Keep in mind that older LGA 1150 boards might only offer M.2 SATA support, while M.2 NVMe options were less reliable back then. Confirm your board’s capabilities before purchasing an SSD.
Is this the board you're referring to? (Image below) It seems unlikely it will work—especially without an M2 slot. Back then, it was a big selling point, but mostly for high-end models. I’ve got an Asus Z97 to confirm that support, so probably not a match.
