MSI B85M-G43 overview

  • 1Description

The B85M-G43 Micro-ATX Desktop Motherboard from MSI features a Micro-ATX form factor with Military Class 4 components, which provide stability and durability. With an LGA 1150 socket, the B85I supports 4th Gen Intel Core, Pentium, and Celeron processors. It supports DDR3-1600/1333/1066 memory, USB 3.0, and SATA 6 Gb/s. B85M-G43 features Intel Small Business Advantage 2.0, which helps in streamlining PC maintenance and security. The motherboard offers 4K high definition visual experience, AMD CrossFireX Support, and has PCIe Gen 3. It features OC Genie 4 that overclocks in one-second, Click BIOS 4 that fine-tunes your system, and Fast Boot helps to quickly boot up and enter OS in few seconds.

The motherboard supports dual and triple-display function in combination of DisplayPort, HDMI, and DVI outputs.

Military Class Essentials

Humidity Protection
The Gen 4 fabric PCB helps to protect motherboard against moisture caused by humid conditions and environments.
ESD Protection
Anti-ESD ICs and fuses on-board help to protect your motherboard from electrostatic damage.
EMI Protection
The optimized EMI proof design helps to keep you safe during a long time computer operation.
High Temperature Protection
Certificated Military Class 4 components help to work stable under extreme conditions.

Military Class 4

Has 10% higher power efficiency for better overclocking and power stability. It has a traditional choke of 40A and a dark choke of a max optimized current of 60A.
Solid CAP
The B85M-G43 has solid capacitors with Low ESR and temperatures, which can provide up to 10+ years under full load. Compared to electrolytic capacitors, solid capacitors have a longer lifespan, and provide a more stable power under high temperatures. More importantly, solid capacitors do not have any liquid materials inside, and thus will not suffer a leak which would infringe upon the product's stability.

Intel Small Business Advantage

It monitors critical software at hardware level. Also Supports schedule backup after hours (even if PC is off*) and blocks unwanted USB devices, file import, or export on company PC's**. 1
Schedule and run maintenance tasks off hours and also reduce boot up wait time, while saving energy and running tasks overnight (even if PC is off*). Connect to your PC's wireless** display to improve in office collaboration. 2
Import/export enhancements with Windows 8 with user-friendly customizations.

Click BIOS 4

Hardware Monitor
Hardware monitor allows you to take control of your system through total fan and check your primary system characteristics in a user-friendly graphical interface.
Board Explorer
Board explorer* gives you detailed info about on-board components on mouse over. Quickly identify connected ports and devices. 3
OC Profile Preview
You can see the differences between your current system settings and any of the eight profiles you can have stored.

Command Center

Fan Curve Tuning
Fan Curve Tuning helps to completely control all your fans to enable you to find the optimal balance of fan performance and silence.
User-friendly configure a RAMDisk to give an optimal speed boost to your system by storing your most used files in it.
Mobile Control
Command Center is user-friendly application that lets you control every aspect of your motherboard with your mobile device. You can remotely monitor your PC wirelessly via your iPhone or Android phone.


OC Genie 4
OC Genie 4 accelerates your entire system and puts it into overdrive. Tuned by the professional over clockers, OC Genie 4 hands you optimal performance on a silver plate.
Fast Boot
Fast Boot helps you to make motherboards boot lightning fast. It also adds the GO2BIOS button within, allowing you to reset your PC and then go straight to the system BIOS.
USB 3.0
Compared to the 480 Mb/s provided by traditional USB 2.0, the USB 3.0's 5 Gb/s offers ten times the transfer bandwidth, which helps transfer a Blu-ray movie in less than one minute. It also boosts transfer rate between your PC and external storage devices.
SATA 6 Gb/s
SATA 6 Gb/s provides double the bandwidth of traditional SATA 3 Gb/s and increases the data transfer rates up to 6 Gb/s between your motherboard and internal storage devices, such as 7200 rpm HDDs, 10000 rpm HDDs, and SSDs.
Super RAID
Super RAID application helps to setup and configure to boost your system performance and stay current with automatic, no-wait updates to your e-mail, social networks, and news via the three Intel key technologies. These technologies include Intel Rapid Start, Intel Smart Response*, and Intel Smart Connect. 4
PCIe Gen 3 motherboard brand
With 32 GB/s transfer bandwidth, PCIe Gen 3 provides a 2x faster transfer rate than the previous generation, this delivers capabilities for extreme gaming and provides optimal performance for current PCIe cards. It offers increased efficiency and compatibility.
4K UHD Support
With an HDMI port, you can enjoy the 4K UHD video playback. It supports 4K UHD (2160p ultra-high definition) signal outputs to provide an optimal visual experience.
AMD CrossFireX
AMD CrossFireX is a multi-GPU performance gaming platform. Enabling gaming power, AMD CrossFireX technology enables two or more discrete graphics processors to work together to improve graphics performance. AMD CrossFireX technology allows you to expand your system's graphics capabilities. It allows you the ability to scale your system's graphics horsepower as you need it, supporting up to four AMD Radeon HD graphics cards. With an AMD CrossFireX gaming technology, the traditional graphics limitations are exceeded, allowing you to enjoy higher performance as well as a high visual experience.
Live Update 5
Live Update 5 is a powerful and useful application for updating the BIOS and drivers, saving your time and lowering the risk of updating. End users can install and run the Live Update 5 software on their computers with the companion CD or downloading the app from the MSI website. It automatically detects the BIOS/Driver/VGA/Utility update and supports Microsoft Windows XP/Vista and 7 (32/64-bit).
MSI's M-Flash has a double advantage which doesn't need extra components and secondly, all your BIOS data will be saved in the USB drive. The stored data have backup and upgrade function and can also be seen as a portable BIOS chip which boot up your PC. It also enables you to earn more BIOS lifespan by reducing unnecessary rewriting process. Avoid unnecessary repair due to accident failures during the upgrading process.
