The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices. Several direct-current voltages are required, and they must be regulated with some accuracy to provide stable operation of the computer.
For example, a 900-watt power supply with the 80 Plus Silver efficiency rating (which means that such a power supply is designed to be at least 85 percent efficient for loads above 180 W) may only be 73% efficient when the load is lower than 100 W, which is a typical idle power for a desktop computer. Thus, for a 100 W load, losses for this ...
FlexATX is a motherboard form factor derived from ATX.The specification was released in 1999 by Intel as an addendum to the microATX specification. It uses a subset of the motherboard mounting holes required for microATX and the same I/O plate system as ATX and microATX.

The internal PSU connector was of the same type used in the AT form factor. One of the more successful features to come out of the LPX specification was its use of more compact power supplies, which later became widely used on Baby AT and even full size AT cases. [ 3 ]
80 Plus (trademarked 80 PLUS) is a voluntary certification program launched in 2004, intended to promote efficient energy use in computer power supply units (PSUs). Certification is acquirable for products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load.
On September 14, 2020, AMD hinted at the physical design of its RX 6000 series through a tweet shared on social messaging service Twitter.At the same time, it launched a virtual island inside the video game Fortnite containing a large-scale rendition of the RX 6000 hardware design, which players could freely explore using the game's Creative mode.
To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. [1] These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended.
