The Bracket PCI To PCI-E 1x Riser Card Extender utilizes a PLX
Technology PEX 8111 or PEX 8112 PCI to PCI Express bridge chip. It will accept
standard or low profile PCI cards. As a generic PCI to PCI Express adapter it
should work well with most PCI cards.
This adapter allows you to use your existing PCI cards in the PCI Express slot
of your mother board. It can accept one of the half height cards designed for 2U
server chassis environments, such as a Firewire or Lan card. The 32bit 33MHz
adapter’s 4 pin connector is connected directly to the power supply of your PC.
The heat generated by the card is very low. The adapter has a bracket with a
large gap to allow you to plug things into the card.
