The ROG G20AJ-US023S Gaming Desktop Computer from ASUS is a small form factor system that is designed for those who require reliability and high performance. Optimized for gaming, but also able to handle standard processing and intensive workloads, this system is powered by a 4th generation 3.2 GHz Intel Core i5-4460 Quad-Core (Haswell) processor, allowing you to run multiple applications simultaneously. If you need more power, the processor can be overclocked to 3.4 GHz and the 8GB of 1600 MHz DDR3 RAM can be upgraded to 16GB.

For long term storage of your files, a 1TB 3.5" SATA hard drive provides ample space to hold your data. Additionally, this drive is outfitted with 8GB of SSD cache memory that the system uses to quickly access frequently-used files and programs. The NVIDIA GeForce GTX 750 graphics card is designed to deliver a sharp, clear picture, while allowing for a wide range of monitors to be used via its one HDMI port, one Dual Link DVI-D port, and one VGA port. If you require extra displays, the GTX 750 can support up to three simultaneous monitors. Whether you are listening to music, watching a movie, or playing a game, the integrated SonicMaster audio controller outputs 8-channel audio, which allows for higher fidelity than standard controllers.

If you would like to connect external peripherals to your computer, such as memory card readers or optical drives, the ROG G20AJ has four USB 3.0 ports and four USB 2.0 ports. Internet connectivity may be achieved using either the Gigabit Ethernet or the 802.11a/b/g/n/ac Wi-Fi. Also included with this workstation are a wired USB keyboard and mouse, an AC adapter, and a power cord.
