What is the most common PSU form factor?
ATX PS/2 is by far the most popular form factor, and will fit in the vast majority of cases. ATX PS/3 is a compatible with PS/2, but is slightly shorter in depth. ATX PS/3 PSUs are less common and used more in smaller cases such as mATX cases.
What is meant by at ATX NLX form factor?
NLX (short for New Low Profile eXtended) was a form factor proposed by Intel and developed jointly with IBM, DEC, and other vendors for low profile, low cost, mass-marketed retail PCs. Officially, the NLX form factor was designed to use ATX power supplies and featured the same soft power function.
What does ATX or SFX refer to in a power supply?
An SFX power supply oftentimes is another name for what many manufacturers refer to as uATX or MicroATX. SFX is a reduced size design closely based on the ATX form factor. The power specifications for SFX vs ATX are nearly the same meaning that SFX PSUs have mostly the same cabling and pin outs.
What is form factor?
Form factor for computers refers to the size, shape, and physical specifications of hardware or hardware components. Computer form factor is used to describe any physical aspect of a computer system.
What is the difference between SFX and SFX L?
SFX-L power supplies have a similar width and height as regular SFX power supplies so they can fit the same cases. The only difference is SFX-L power supplies are slightly deeper to accommodate the larger fan. Apart from its high output, the 800W SFX-L has a high effieciency rating.
What is XT form factor?
The XT (an abbreviation for eXtended Technology) was the first form factor introduced in 1983 by the then popular IBM Personal Computer XT, or simply IBM XT. The IBM XT was intended for business users and can cost up $3,000 USD and more at the time, or about $7,800+ USD in 2019 after factoring in inflation.
What is ATX vs microATX?
The Micro-ATX generally measures in at 9.6 inches by 9.6 inches, while the ATX board measures 12 inches by 9.6 inches. The Micro-ATX typically has fewer SATA ports and M. 2 slots than an ATX variant, making it a worse choice for users who need a lot of storage.
What is form factor SFX?
When referring to a power supply, SFX is a form factor similar to the ATX form factor, except it does not include the -5V rail. This rail was used by some ISA expansion cards, but today’s motherboards no longer feature the ISA expansion bus, or slot), so the -5V rail is not needed.
What is power factor and form factor?
Power factor tells us about the phase shifts in sinusoidal waveforms and the reactive current when the load includes a magnetic (i.e. inductive) component. Form factor is a simple way of showing the degree of distortion of the waveform.
What is form factor formula?
Definition: The ratio of the root mean square value to the average value of an alternating quantity (current or voltage) is called Form Factor. The Form Factor for the various sinusoidal waveforms are as follows: For a sine wave, it is π/2√2 = 1.11072073. For a half-wave rectified sine wave, it is π/2 = 1.5707963.
How are form factors different from power supplies?
The backside of every power supply looks essentially the same. Each has a fan for cooling. For an ATX form factor, the fan is always taking the air out of the computer. Conversely, an AT form factor is pulling air into the case. A power switch turns the power supply on and off. An external power connection accommodates the power cord.
Is the motherboard form factor the power supply form factor?
A computer manufacturer can also have a proprietary power supply form factor that is not compatible with different computer models or other vendors’ machines. Laptop power supplies are commonly proprietary. The motherboard form factor and the power supply form factor must fit in the case and work together.
What makes up the form factor of a computer?
There are three main components that must have the same form factor: Case – houses the hardware components of the computer system Motherboard – The main circuit board of the computer system; all system components are plugged into the motherboard Power supply – Provides power to the motherboard and all other installed hardware components
What are the different types of power supplies?
Just as motherboards come in different shapes and sizes, so do power supplies. Today’s power supply form factors are ATX, ATX12V v1.x, ATX12V v2.x, and micro-ATX.
