The MSi H55M-P33 is a mid-range motherboard similar to the MSi H55M-P31. The H55M-P33 sports a number of minor improvements over the H55M-P31, all of which are proprietary MSi technologies.

Otherwise, the H55M-P33 and H55M-P31 sport the same features, including an LGA1156 CPU socket and support for up to 16GB of DDR3 RAM.

The H55M-P33's i-Charger utility allows for charging of any iPod, iPhone or iPad device directly from your computer while its Live Update 4 BIOS updating technology automatically checks for and applies BIOS updates in the background, making BIOS updates safer and easier.
