A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
80 Plus. Logo. 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.
Corsair Gaming, Inc. (stylized as CORSAIR) is an American computer peripherals and gaming brand headquartered in Milpitas, California. [4] Previously known as Corsair Components and Corsair Memory , [ 5 ] it was incorporated in California in January 1994 originally as Corsair Microsystems and reincorporated in Delaware in 2007.

ATX. An ATX motherboard. Comparison of some common motherboard form factors (pen for scale) ATX (Advanced Technology Extended) is a motherboard and power supply configuration specification, patented by David Dent in 1995 at Intel, [1] to improve on previous de facto standards like the AT design. It was the first major change in desktop computer ...
[7] [8] [9] They may also hold two computers (as is the case with the Corsair 1000D) and dual power supplies (Corsair 900D). [10] [11] Mid-tower cases are smaller, about 46 cm (18 in) high with two to four external bays. They may also hold two computers. [12] A mini-tower case will typically have only one or two external bays. [13]
A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains ...
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
CPU core voltage. Appearance. The CPU core voltage (VCORE) is the power supply voltage supplied to the processing cores of CPU (which is a digital circuit), GPU, or any other device with a processing core. The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws.
