Detailed purchase criteria:
– The physical format: in descending order of the sizes, it is the formats E-ATX, ATX, μATX and MiniITX, the most used being the ATX and the μATX. ATX motherboards offer more PCI-E and PCI ports so you can mount more expansion cards to these formats, such as graphics cards, sound cards, network cards, and TV tuner. However, as motherboards integrate more and more functionalities, opting for a motherboard μATX cheaper than its equivalent ATX is a wise choice in a majority of cases. It should also be noted that the motherboards in the μATX format can be placed in the ATX enclosures. View the top shop for computer repair augusta here.
The Mini ITX format offers reduced connectivity and is specifically dedicated to mini PCs. On the contrary, the E-ATX format, reserved for very rare very high-end models, is a little more bulky than the ATX format.
– The socket: this is physically the support processor on the motherboard which makes it compatible with a family of processors adopting this support.
– The chipset: in order to segment the market, AMD as Intel provide different chipsets for each socket. Other motherboards in the same socket have different chipsets and the more expensive ones provide support for a wider connection (more USB ports, more SATA ports or even more memory slots) as well as some specific features Faster memory support, some video outputs, overclocking, SLI / Crossfire). However, there is no appreciable difference in performance between these chipsets and the midrange models, which incorporate sufficient connectivity for the majority of users. Note that often the reference of the motherboard bears mention of the chipset used by the latter.
– Memory slots: except on high-end Intel platforms where there are 8 of them, the motherboards offer 2 to 4 DIMM slots. The presence of only 2 memory slots is not necessarily inconvenient since you can opt for a single high capacity slot in order to keep a memory slot free for a later upgrade.
– Video outputs: the vast majority of processors offer an integrated graphics card that will allow you to manage your screen provided that the motherboard has appropriate video connections.
– Connections and internal ports: PCI-E, PCI, SATA, M.2, USB internal, internal audio and fans.
The PCI-E ports are mainly available in 16x version (for mounting graphics cards) and in 1x version (for sound cards and Wi-Fi cards, for example). There are different revisions of PCI-E ports but there is compatibility and there is in practice no significant difference in performance. All ATX and μATX motherboards include at least one 16x PCI-E port plus one 1x PCI-E port.
The PCI-E 1x ports tend to replace the PCI ports, so the PCI-E ports will disappear: in the case of a machine upgrade, you will be careful to have PCI slots if you want to re- Extension of this type.
SATA connectors are used to connect hard drives, SSDs and drives / drives. They exist in different revisions but in all cases there is compatibility and there is in practice no significant difference in performance, even for SSDs in system disk. Rarely, an M.2 port will be used to mount an SSD in this format. Here also different versions exist, the most powerful being the ports M.2 PCI-E 3.0 4x with support NVMe.
Internally, USB2 and USB3 exist with separate connectors. They are usually present both and will serve to connect the front panel ports of the case, and / or an internal memory card reader. They can also allow the addition of external ports via the use of a square.
