What is a 4 pin power connector?
The ATX 4 pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.
the PCI Express power connectors on the graphics card. There are two types of power connectors: 6-pin: this power connector can provide up to 75 watts. 8-pin: this power connector can provide up to 150 watts.
- PC cases themselves are often referred to by these three form factors, but the terms more accurately refer to the size of the motherboards they can host. ATX boards measure 12 by 9.6 inches, MicroATX up to 9.6 by 9.6 inches (they're sometimes smaller), and Mini-ITX 6.7 inches square.
- Any standard ATX case will fit any standard ATX motherboard but dosn't necessarily support Micro ATX or Mini ATX. It depends on the mid tower. I have a full tower and even though it's easily big enough to fit them it dosn't support Mini ATX, Flex ATX or EmbATX.
- Both mini-ITX and micro-ATX are small form factor motherboards used in small computers. As motherboards, both ATX and ITX provide the basic features that can run a computer. “Small form factor motherboard” is the common term for any motherboard below a certain size.
