There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
Such systems may constitute personal computers (including desktop computers, portable computers, laptops, all-in-ones, and more), mainframe computers, minicomputers, servers, and workstations, among other classes of computing. The following is a list of notable manufacturers and

The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.
