ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot.
What is ATX power connection?
An ATX style connector is a replacement for the older P8 and P9 AT style connector. It is one of the largest connectors inside a computer. It connects a power supply to an ATX style motherboard. As shown in the picture, the 20-pin cable is a multi-color cable and may be labeled as P1. Note.
Do I need an ATX PSU?
No, you don’t need an atx power supply for atx motherboard. You do need an atx case to fit a atx motherboard.
What is the main purpose of the power supply?
The purpose of a mains power supply is to convert the power delivered to its input by the sinusoidally alternating mains electricity supply into power available at its output in the form of a smooth and constant direct voltage.
What is the role of the ATX power connector slot in the motherboard?
ATX Optional Connector This connector has two rows of three pins each to provide the signals and voltages. The computer can use these signals to monitor and control the cooling fan, monitor the +3.3v power to the motherboard, and provide power and grounding to IEEE 1394 (FireWire) devices.
What is the difference between AT and ATX power supply?
AT-style computer cases had a power button that is directly connected to the system computer power supply. An ATX power supply is typically controlled by an electronic switch. Instead of a hard switch at the main power input, the power button on an ATX system is a sensor input monitored by the computer.
What is a good wattage for a gaming PC?
A gaming PC should have between 500 and 550 watts, but it will still depend on how you will use your gaming PC. Instead of getting the most power available, it’s better to buy a power supply unit that aligns with your needs to lower overall costs and improve efficiency.

How do I choose the right power supply for my electronics?
Power Supply Voltage If your device needs 9V, you need a 9V power supply. If your device needs 5V, you need a 5V supply. Also, if your device needs a DC voltage (which is the most common), you need a DC output from your power supply. If your device needs AC voltage, you need an AC output.
What are the 4 stages of power supply?
Power Supplies Transformer – steps down high voltage AC mains to low voltage AC. Rectifier – converts AC to DC, but the DC output is varying. Smoothing – smooths the DC from varying greatly to a small ripple. Regulator – eliminates ripple by setting DC output to a fixed voltage.
Why is the power supply important for PC?
The power supply (PSU) is a critical part of any PC. It powers all the components in your PC, and a bad or faulty one can bring everything down.
What are the 3 types of power supply?
There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching.
What is ATX 12V power supply?
An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version.
What is ATX 12V 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.
What is ATX 12V on motherboard?
8PIN ATX 12V. Connects to the motherboard EPS 12V socket. Provides additional power to the CPU. 4+4 Pin ATX/EPS. A hybrid of the 4 PIN ATX12V and EPS 12V connectors that can be split in half or combined to accommodate either the EPS 12V Socket or the ATX 12V socket.
Why do the USB 3.0 ports need a power cable?
Why do the USB 3.0 ports need a power cable? According to USB specification, a host (computer) should be able to deliver some power over USB cable. This decision was made by USB consortium on purpose in order to simplify connecting small devices without a need for additional cable.
Can I plug my PC into an extension cord?
Yes, you can plug a PC into an extension cord because computers do not draw enough current to present a danger. That applies to laptops, desktops, and Mac computers. In fact, computer owners do this so frequently that many people don’t even question the practice.
How do I choose a power supply for my motherboard?
If there is a sudden demand for more power, your PSU should be able to handle the higher output briefly, but should not be expected to run at those higher wattages continuously. Always make sure the PSU you purchase has sufficiently high continuous power output, and don’t choose solely by peak power capabilities.
How is ATX different from AT which now?
Power connectors differ between AT and ATX motherboards. AT motherboards use two 12-pin plugs to power the motherboard, while an ATX motherboard uses one 20-pin plug for the power supply. When using an ATX form factor motherboard, you must use an ATX power supply.
What is ATX mode?
AT and ATX stand for Advanced Technology power supply and Advanced Technology Extended power supply. Both are types of Switch Mode Power Supply (SMPS). Switch mode power supply provides electrical power to an electrical load. SMPS uses a switching regulator for efficient conversion of electrical power.
