Intel Deep Power Down
Intel's Deep Power Down mode refers to an energy saving mode on current Intel processors. The deep power down command is used to switch off all unused processor cores in their entirety. The power control unit integrated into the process controls the core activities. The power gate integrated into the mainboard then switches off the individual cores as required (see C6 as well).
Multi-GPU (see GPU)
A multi-GPU is comprised of several individual GPUs. This technology can be used through interconnection to one graphics card or distributed to several graphics cards. In either case the individual GPUs communicate with one other to process and depict image data as quickly as possible.
When an external power supply such as be quiet! NOTEBOOK POWER is used, the output voltage for the power supply can be manually adjusted to the laptop's voltage. The user of a unit like the 65W model has six preset output voltages available: 12V, 15V, 16V, 18V, 19V and 20V.
Mini ATX (µATX, ITX, Flex ATX)
The Mini-ATX form factor represents a miniaturisation of the ATX form factor. ATX mainboards are dimensioned to roughly 300 x 250 mm, while Mini ATX mainboards are only around 280 x 210 mm. The current smallest mainboard features the Pico ITX form factor and measures just 100x70mm. To fit these smaller designs, power supplies are also offered in small designs. Examples of this include SFX and TFX power supplies.
The Overclocking Key is a concept developed by be quiet! to connect several 12V rails. The key is used in the DARK POWER PROP8 series of power supplies. Several 12V rails can be connected into a high-powered 12V rail. This is particularly beneficial for high-performance computer systems that work at the edge of their performance envelope (overclocking) and for which standard power supply via divided 12V rails is insufficient.
Over Voltage Protection protects the PC against overly high voltages. To prevent damages to the PC, the power supply turns off when an over voltage is present.
This important protective circuit stands for Over Temperature Protection. Heat is created within the power supply during control actions. It the interior of the power supply becomes overheated, the OTP protects the electronics against damages.
Similar to the OCP, the OPP is one of the protective circuits built into the power supply. OPP stands for Over Power Protection. If a power supply is operated at an excessive power level, the OPP protects the power supply against a technical breakdown.
The OCP is one of the power supply's protective functions. It stands for Over Current Protection. If a voltage rail draws more current from a power supply than the power supply specification permits, then the OCP intervenes and switches off the power supply.
Pulse Width Modulation (PWM) is a modulation of the duty cycle. The duty cycle reflects the switch between two fixed values, such as 0V and 5V. The frequency of the signal never changes in the process. The only factor that varies is the rhythm of "on time" and "off time". For example: a 50% PMW would set a fan – such a CPU or casing fan – running at approximately half of its maximum RPM.
