What two types of connectors are attached to the motherboard?

Central processor is one of the main components and the “heart” of any computer. If it is not connected, the system unit will not start, and it’s very important to install it correctly. When choosing a processor, you need to focus on what kind of motherboard is used, or vice versa. The fact is that there are 9 modern standards of processor connectors, having different pinouts or not compatible with each other for other reasons.

Please note Most often the space around processor connector on the motherboard is quite “deserted”. The thing is that there has to be installed a cooler on top of the processor to cool the “stone”, which can be quite impressive in size. Video card connector on a motherboard The next connector on the motherboard, which for sure will be required when building a computer, is a video card connector. Some time ago there were two types of connectors used to connect video card to the motherboard – AGP and PCI Express. Nowadays all video cards are connected to the PCI Express connector only. Most often, the PCI Express connector is located in the lower left corner of the motherboard. It can serve not only for connecting a video card, but also other devices. Please note The PCI Express connector can be presented in several types: PCI Express x1, PCI Express x4, PCI Express x16. To connect the standard video card you will need the last one of the listed connectors. Other connectors may not always be present on modern motherboards. The PCI Express X16 connector for video card connection can be of different versions. As of 2017 there are 4 types of PCI Express connectors:
These connectors differ from each other only by their throughput. In the same time they are inversely compatible. If you are connecting a device made for PCI Express 2.0 to the PCI Express 3.0 slot, it will most likely work without any problems. But if done vice versa, a device designed for a higher type of connector may not have enough bandwidth to fully or partially perform it’s functions. Please note On some motherboards, you can find a PCI slot located beside the PCI Express. This connector is now almost not used, but if necessary, you may install some additional elements in it. Memory (RAM) connector on the motherboardConnectors for RAM are most often located to the right from the processor (sometimes they can be located on two sides). Modern motherboards have at least 4 connectors. Currently, slots for RAM connection belong to the DDR3 protocol. Before there were used DDR1 and DDR2, which are no longer corresponding to the current bandwidth standard. DDR1, DDR2 and DDR 3 connectors and devices are not compatible. Which means that you will not be able to install the DDR1 device into the DDR3 connector. It should be noted that on the modern motherboards, you can see that several RAM connectors are made in one color, and several in the other. This is due to the fact that different channels are marked with different colors. If you have several memory slots, it’s best to plug them into connectors of the same color. Hard disk connector on the motherboardOn the motherboard (most often in the lower right part of it) there are several connectors for the hard drive. These connectors are called SATA, and they come in three versions: SATA 1.0, SATA 2.0, SATA 3.0. Most often these connectors are color-marked, differing from all other connectors on the motherboard. All versions of SATA connectors are backward compatible, and they only differ by speed. SATA 3.0 connector is the fastest at the moment, therefore it is used in all modern motherboards. Power connector on the motherboardOn the right side of the motherboard there is another important connector, which serves to power the motherboard. It usually consists of 20 or 24 contacts and serves to connect wires from the power supply. Motherboard can not work without getting power through this connector. Above we have examined all most important motherboard connectors that are used to plug the main components of any system unit. In fact, the amount of connectors is much larger, some of them serve to connect buttons from the computer case, others to plug the case connectors or additional power and so on. Which connectors are used in motherboard?Motherboard Diagram. What are the two types of motherboard?The most common motherboard form factor is ATX. The different types of ATX are known as micro-ATX (sometimes shown as µATX, mini-ATX, FlexATX, EATX, WATX, nano-ATX, pico-ATX, and mobileATX). A smaller form factor is ITX, which comes in mini-ITX, nano-ITX, and pico-ITX sizes.
What two connectors are needed to supply power to the motherboard?On modern power supplies this will either be a straight 24 pin connector, or a 20+4 pin connector. Some motherboards only require a 20 pin motherboard power connection, in which case you would only plug in the 20 pins (and not plug in the 4 pins). But modern motherboards will require a 24 pin power connection.
