Power Supply Form Factors: ATX, TFX, SFX PSUs
Powers supply unit arrives in various form factors to accommodate different computer case sizes and designs , form factor refers to different physical dimensions and specifications of PSU’s below is the description about three power supply form factors: ATX, TFX, SFX PSUs one by one-
1. Advanced Technology extended(ATX)
Advanced Technology extended(ATX) is a power supply form factor which are designed for desktop computers so there dimension is 150 x 86 x 140 mm which make it compatible in normal desktop cases. they are widely adopted and easily available and are also suitable for a wide range of desktop systems but it’s large size make it unusable in compact cases.
2. Thin Form Extended (TFX)
Thin Form Extended(TFX) is a Power supply form factors designed for slim desktops and compact systems so small dimension is kept in mind so it has dimension of 85 x 65 x 175 mm , they are compact and thinner then ATX which make them Suitable for slim or low-profile desktop systems . they are available in limited quantity and hence they are generally slightly more expensive than ATX PSUs.
3. Small Form Factor Extended (SFX)
Small Form Factor Extended (SFX) is a Power Supply Form Factors designed for gaming consoles and mini-ITX gaming computers and are even more compact than TFX and ATX has dimension of 125 x 100 x 63.5 mm . they are Ideal for small form factor (SFF) and mini-ITX cases and also provides power for compact gaming systems but they are generally more expensive due to specialized design and also have Limited power output when compared to larger form factors.
What is Power Supply Unit (PSU)?
A PSU is a type of internal hardware used in information technology systems. Power Supply Units (PSUs), despite their name, transform power rather than providing it to systems. In particular, a power supply regulates the DC output voltage to the precise tolerances needed for contemporary computing components in addition to converting the alternating high voltage current (AC) into direct current (DC).
