Adds four M.2 NVMe slots via a PCIe 3.0 x8 link with a PEX8724 switch, heatsink and active fan cooling
This expansion card uses a PLX PEX8724 switch to present four M.2 NVMe slots through a single PCIe 3.0 x8 connection. It accepts 2230, 2242, 2260, 2280 and 22110 form factors. The board targets servers, workstations and high-capacity storage builds that need more NVMe endpoints than the platform provides natively.
A full-profile bracket comes pre-installed alongside a heatsink-and-fan assembly that covers all four drives. The package also supplies four SSD mounting screws with nuts and four heatsink screws. These parts let the installer secure drives and cooling without sourcing extra fasteners or brackets.
The upstream x8 Gen 3 link caps aggregate throughput at the bus level, so four simultaneous drives share that pool. The card operates from 5 °C to 50 °C and stores from -25 °C to 70 °C. It does not add NVMe support to systems that lack PCIe 3.0 or an x8 electrical slot.

The card ships with a heatsink and fan cooling system; the fan is a moving part that typically requires replacement first under continuous operation.
The PCIe 3.0 x8 host link caps aggregate bandwidth at 6.0 Gbps, so that bus limit is reached before individual SSD limits.
Active fan cooling keeps the PEX8724 switch within the 5 °C to 50 °C operating range; fan noise is present whenever the card is powered.
