Minisforum Launches AR900i: A $559 Core i9-13900HX Mini-ITX Platform

Minisforum has launched a new high-performance Mini-ITX motherboard that’s based on Intel’s 13th Generation Core HX mobile parts. The upsized, highly integrated AR900i platform promises to bring together the power efficiency benefits of a mobile platform with desktop-class performance and features – and all at a rather moderate price.

Minisforum itself calls its AR900i platform an ultimate mobile-on-desktop (MoDT) platform and indeed it is quite capable thanks to its 14-core Core i7-13650HX (up to 4.90 GHz, 24 MB LLC) or 24-core Core i9-13900HX (up to 5.40 GHz, 36 MB LLC) processors, which are designed for high-end laptops. These CPUs are configured to dissipate up to 100W of thermal energy (lower than 157W set by Intel), so they are equipped with a rather advanced cooling system with four heat pipes and a 12-cm fan. The CPUs can be mated with two DDR5 memory modules in an SO-DIMM form-factor. 

Being aimed primarily and gamers seeking for both performance and portability, the Minisforum AR900i comes with a PCIe 5.0 x16 slot for graphics cards as well as four M.2-2280 slots for PCIe 4.0 SSDs (two on top of the motherboard and two on the lower side). To ensure consistent performance of high-end drives under high loads, there is an active cooling system for them. Meanwhile, it is unclear how loud this SSD fan is. Speaking of fans, the motherboard has a connector for a system fan, which will certainly come handy for high-end builds.

When it comes to expandability, the Minisforum AR900i platform does not disappoint and resembles other high-end Mini-ITX motherboards with an M.2-2230 slot for a Wi-Fi and Bluetooth adapter, a built-in 2.5 GbE, three display outputs (DisplayPort 1.4, HDMI 2.0, USB4 Type-C), plenty of USB ports (USB4, two USB 3.2 Type-A, two USB 2.0 Type-A), and 5.1-channel audio connectors.

Getting a high-end CPU and a high-end motherboard quite an investment nowadays, so one would expect Minisforum’s AR900i to be quite expensive. Indeed, it is priced at $689, but since the manufacturer sells virtually all of its products with a discount, it can be obtained for $559.
