Like the Biostar TP45 HP, the ECS P45T-A uses only four of the chipset’s six PCI Express lanes to support two onboard controllers and two x1 slots. ECS chooses the RAID-capable ICH10R however, getting another leg up on at least one competitor.
ECS’s single eSATA port gives it a lead over Biostar and ASRock products, but lacks the IEEE-1394 FireWire controller and digital audio connectors offered by ASRock. The legacy serial communications port of the P45T-A is out-of-place on any modern motherboard, but the six analog audio connections are still viable.
JMicron’s JMB361 controls the Ultra ATA 133 and eSATA ports, using a PCI Express interface to support up to 250MB/s bi-directionally.
The tiny Atheros AR8121 Gigabit Network controller also uses PCI Express for peak performance.
Realtek’s ALC883 is rated at a reasonable 95db signal-to-noise ratio, and we’ll try to confirm that rating in our audio quality tests.
