A power-saving mode for monitors is usually part of the power management options supported in modern operating systems, though it must also be supported by the computer hardware and monitor itself. Using a screensaver with a flat panel or TFT LCD screen not powering down the screen can actually decrease the lifetime of the display, since the ...
By the late 1990s, most new monitors implemented at least one DPMS level. [citation needed]DPMS does not define implementation details of its various power levels; [3] while in a CRT-based display the three steps could logically be mapped to three blocks to be shut down in order of increasing savings, thermal stress, and warm-up time (video amplifier, deflection, filaments) not all designs ...
A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.

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.
