Asus AT3N7A-I compatibility review

The Asus AT3N7A-I uses the Intel Socket 437 CPU socket. Any compatible Intel CPU will have the same socket entry. It uses the aging DDR2 memory type, with maximum speeds of up to 800 MHz, and 2 DDR2 slots allowing for a maximum total of 4 GB RAM. DDR2 memory is exceptionally out of date, and considering how cheap DDR3 RAM is, using a motherboard with only DDR2 compatibility in a modern system build would be a very bad idea.

Released on 26 Aug 2009, the Asus AT3N7A-I is now over 10 years old, which means it is extremely out of date and is based on very aged technologies. This motherboard will be dwarfed in performance by its modern counterparts, and will likely have very little support from Asus.

The Mini-ITX form factor is common for low-power system builds. Lower power requirements allow for less cooling, which in turn means a quieter PC. As such, the Asus AT3N7A-I may be ideal for activities that require minimal sound excess, such as watching movies. For a gaming PC, a traditional ATX form factor is recommended, which would be more generally compatible and would provide more expansion options than Mini-ITX, but Mini-ITX is still a solid choice.

The Asus AT3N7A-I has 3 SATA 2.0 hard drive slots. These allow for data speeds of up to 3GB/s. SATA 2.0 is a very common standard, and despite the emergence of SATA 3.0 - whose potential is difficult to reach currently - SATA 2.0 remains a viable option.

The Asus AT3N7A-I supports onboard graphics. This allows for integrated graphics when paired with a compatible CPU that supports them. Integrated graphics are a cheap alternative to using a graphics card, but should be avoided when frequently using modern applications or games that require intense graphical processing. There are 0 PCIe x16 slots on this motherboard. The Asus AT3N7A-I does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.

The Asus AT3N7A-I has 8 USB 2.0 slots but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. If planning on building a new system, a motherboard with USB 3.0 is likely to have a longer life cycle, however.
