To output video signals to a monitor, modern PCs use a graphics processing unit, or GPU. Unlike the CPU, which is a general-purpose processor that can perform most any kind of mathematical operation, the GPU greatly speeds up certain types of calculations that are necessary for basic display output and video playback. More powerful GPUs can perform those calculations quickly enough to run the 3D simulations necessary for gaming in real time.

Closed-loop liquid cooler or all-in-one liquid cooler, circulates water-based coolant through hoses that run between a pump head and a radiator like the one you'd find in your car. The pump head has a copper plate on its base that contacts the metal cover of the processor and transfers heat into the liquid sealed into the system that's circulating on the other side. Fans mounted to the radiator then transfer heat from the liquid to the surrounding air.

Power supplies come in fully modular, semi-modular, and non-modular varieties, each of which refer to a type of cabling system. Fully modular units don't have any fixed cables running out of their enclosures. Instead, you install only the cabling you need using sockets on the front of the unit. Semi-modular units might have fixed cables for the highest-current wiring, but let you customize the remainder of the cables for storage devices and peripherals. Non-modular PSUs come with all of their cabling hard-wired.

The number of wireless devices in our lives is multiplying at a torrid pace. Tech-savvy households can easily include over a dozen devices between smartphones, tablets, PCs, game consoles, smart TVs, digital assistants, and an expanding array of IoT gear. That’s a lot to manage under one roof, especially during prime time, when concurrent streaming, surfing, and gaming sessions all want their share of available bandwidth. With this in mind, we’ve deployed it across a family of new routers capable of keeping up with your appetite for digital devices.
