NFHK 7 Ports PCI-E to USB 3.0 HUB PCI Express Expansion Card Adapter 5Gbps for Motherboard
Quick View

Giving a computer additional capabilities requires fitting the computer with an add-on card, also called an expansion card, interface card or just plain card. Expansion controller cards have sockets that connect to conductors carrying data within the system. The connector you use depends on the card and computer. Cards provide communications interfaces, extra memory, video sound I/O capabilities, system interfaces for discs or tape backup devices and additional processors in general. Controller cards are an excellent example of an add-on card because the card acts as an interface for the motherboard, and other computer components like HDD, optical drives and keyboards. Add-on cards are suitable for use with printers and other devices in office environments.

Add-on Cards Improve Audio for Gaming, Movies and Music

Having a computer with a dynamite sound card or audio system makes gaming, watching movies and listening to music a lot more enjoyable and immersive. The sound card is an add-on card that facilitates each audio component, including multimedia applications such as music composition, presentations, audio editing and entertainment. Most PCs offer a standard sound experience, and improving the audio quality is simple with sound card accessories. Some standard accessories in the collection are USB audio interfaces, high-performance headphone amplifiers and virtual 7.1 channel surround sound systems. You can also add parallel printer cards to increase or upgrade the system.

PC Game Controllers Raise the Full Immersion Experience

Kicking your gaming to a whole new level of experience necessitates selecting a PC game controller that mirrors the gear handled in real-life situations. Some players feel comfortable using straightforward game controllers, like racing wheels or flight joysticks. Those who want the ultimate experience with full immersion in their favorite game need to consider empowering their system's performance. With the introduction of more elaborate controllers, such as VR headsets, rudder pedals, pro racing wheel stands and flight simulation, the upside is the new controllers require no new add-on cards. Plug the game controller USB cable into your system and Windows® 10 will detect it, and you are set up. Being immersed in your gaming scenario means using suitable PC game controllers. The performance will leave you feeling like you just flew a plane or raced a car like a professional, without leaving your house. As you track your statistics and see how much your game scores improve, empowering your system with quality PC controllers will prove worthwhile.

VR Accessories Possibilities Are Endless

Distinguishing the many uses of Virtual Reality (VR) accessories goes beyond gaming. Many fields in the educational and business community utilize VR accessories for vocational training, engineering and designing. The accessories begin with headsets, cables, connectors, 3D glasses, Bluetooth® remote controls and carrying cases. Some accessories come as a bundle, so you have gear and hardware upgrades like controller cards. Once the equipment is in place, you can begin gaming, training or virtual conceptualizing with high efficiency. The possibilities for you to produce and discover using the VR equipment and software are endless.
