Q: Is this riser required for adding a low-profile PCIe card to a C220 M8?
A: Yes. It provides the mechanical and electrical interface for a half-height PCIe Gen5 x16 slot at Riser 1A.

Q: Will Gen4 or Gen3 adapters work in this Gen5 riser?
A: Yes. The slot is backward compatible with older PCIe generations as supported by the server platform.

Q: Does it support full-height cards?
A: No, it is designed for half-height (low-profile) adapters.

Q: Do I need additional power cables?
A: Typically no. Most low-profile adapters draw power from the PCIe slot. Some specialty cards may require vendor-provided cables.
