PCI Express (PCIe) slots are replacing PCI slots within desktop PCs and servers. PCIe cards have a similar form factor and user experience as the older PCI cards, however they are both faster and require less power and are becoming the card type of choice. Brainboxes PCI Express cards will fit in any PCI Express slot - x1, x4, x8 & x16.

Brainboxes manufacture an extensive range of PCI Express cards with 1 to 8 ports, RS232 or RS422/485, low profile or standard height, and with or without cables.
