The Motherboard

So far ECS released three models based on AMD 890GX: A890GXM-A, which is the model we are taking a look; A890GXM-AU, which is identical to A890GXM-A but featuing USB 3.0 ports; and IC890GXM-A.We created a table showing the main differences between these products. As you can see all are ATX-sized motherboards with basically the same features, with A890GXM-A and A890GXM-AU being more complete because they have three PCI Express x16 slots, two Gigabit Ethernet ports and more video connectors. Also A890GXM-A and A890GXM-AU use only solid capacitors, while IC890GXM-A uses solid capacitors only on its voltage regulator circuit, using regular electrolytic capacitors on the rest of the board. A minor difference is on the voltage regulator section, where IC890GXM-A uses a simpler 3+1 phase configuration, while the other two boards use a 6+1 config.
