Motherboards with steel PCIe slots

Steel PCIe connectors

— presence of reinforced steel PCIe connectors on the motherboard.

Such connectors are mainly found in gaming (see "By Category") and other advanced types of motherboards designed for powerful graphics adapters. PCIe 16x slots, which are specifically intended for such graphics cards, are usually made of steel; in addition to the slot itself, the mounting to the board also has a reinforced construction.

This feature provides two key advantages compared to traditional plastic connectors. Firstly, it allows for the installation of even large and heavy graphics cards with maximum reliability, without the risk of damaging the slot or the board. Secondly, the metal connector acts as a protective shield and reduces the likelihood of interference; this is especially useful when using multiple graphics cards installed side by side, "side-by-side."
