The MSI H81M-P33 uses the Intel LGA 1150 CPU socket. Any compatible Intel CPU will have the same socket entry. It uses the DDR3 memory type, with maximum speeds of up to 1600 MHz, and 2 DDR3 slots allowing for a maximum total of 16 GB RAM.
Released on 20 Jun 2013, the MSI H81M-P33 is now over 5 years old, which means it is extremely out of date and is based on very aged technologies.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 MSI.
The Micro-ATX MSI H81M-P33 should fit into all ATX cases, but its smaller size allows you to downsize your system build as a whole. Its size comes at the cost of features, so there are likely to be far fewer connections and expansion options available than in a larger motherboard.
The MSI H81M-P33 has 2 SATA 3.0 hard drive slots. These allow for theoretical data transfer speeds of up to 6GB/s, as opposed to the 3GB/s of SATA 2.0. Generally speaking, only high performance hard drives, specifically solid-state drives, will be able to take advantage of the bandwidth potential of SATA 3.0 ports, though it is backwards compatible, so you do not have to take advantage. This motherboard also has 2 SATA 2.0 slots, so numerous SATA hard drives can be connected if desired.
The MSI H81M-P33 does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 1 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of PCIe v2.x, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the MSI H81M-P33's PCIe v2.x. The MSI H81M-P33 does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.
The MSI H81M-P33 has 6 USB 2.0 slots and 2 USB 3.0 slots. USB 3.0 slots are theoretically capable of data transfer speeds of up to 5 Gbit/s, which is over 10 times faster than the USB 2.0 top speed of 480 Mbit/s. Although USB 2.0 slots alone currently serve as well as ever, an upgrade would better future-proof your system as more USB 3.0 compatible peripherals emerge.
