CrossFire refers to a function in which multiple graphics cards are operated within one computer. The technology comes from AMD and is the equivalent to NVIDIA's SLI technology. Operating two graphics cards in a CrossFire configuration provides greater graphics card performance for the computer. All current dual GPU graphics cards from AMD are based internally on CrossFire.
CPU is a common acronym for "Central Processing Unit". The CPU described a computer's primary processor.
If not all cables are permanently attached to the power supply, then one speaks of a cable management system. Unused cables can be removed from the power supply using the plug/socket principle. The user can also select which cable is connected to the power supply and which are unused and can hence be removed. This keeps things more tidy in the computer casing and promotes improved air circulation.
To lay the cable connected to the power supply cleanly into the casing and prevent a tangle of cables, the cables are often coated within a tight-mesh web. Besides a nicer visual appearance, the coating also provides improved air circulation within the casing.
