As with its TP45 HP, Biostar’s TPower i45 uses two of the ICH10R’s six PCI Express lanes for onboard controllers and two for PCI Express x1 slots, leaving two pathways unused. But unlike the TP45 HP, the TPower i45’s third-party ATA controller provides eSATA ports on the I/O panel.
Even on this better-featured model, Biostar provides no digital audio connections on the port panel, instead including a break-out cable for internal connections in its installation kit.
Marvell’s 88SE6121 ATA controller sits beside the Ultra ATA connector, supporting two Ultra ATA drives and two eSATA ports.
A Realtek RTL8111C Gigabit Ethernet controller gets all the bandwidth it needs from a PCI Express connection.
Similar to the ACL888 found on Biostar’s less expensive motherboard, the ALC888S provides the same 97db signal-to-noise ratio but with dual, rather than single, digital outputs.
