The primary task of the Power Supply Unit (PSU) is to provide your motherboard with power. This is done via the 20-pins or 24-pins connector. A 24-pins cable is backwards compatible with a 20-pins motherboard, often this cable can be split into 20- and 4-pins (like in the image above).

What is the power connector on a motherboard?
The ATX 24-pin power supply connector is the standard motherboard power connector in computers today. The connector itself is a Molex 39-01-2240 connector, often called a Molex Mini-fit Jr.
Which power cable usually connects the power supply to the motherboard?
The industry standard ATX power-supply–to–motherboard main connector is the Molex 39-29-9202 (or equivalent) 20-pin ATX style connector (see Figure 3.7). First used in the ATX form factor power supply, it also is used in the SFX form factor or any other ATX-based variations.
How do you connect a power supply to a motherboard?
How to Connect PSU Cables
- Connect your power supply cables beginning with the 24-Pin Motherboard connector.
- Next, connect the 8-Pin CPU/ Motherboard cable. …
- Next, connect the 6 or 8-Pin PCI power cable to your video card. …
- Next, connect your storage or disk device such as your HDD, SSD, or DVD Drive.

What two types of connectors are attached to the motherboard?
There are two primary types of connectors found internally: socket connectors and power connectors. Socket connectors are designed for use with flat ribbon cable, and are generally used to transfer data among devices.
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.
Original ATX power supplies connect to the motherboard with a 20-pin connector. Newer ATX 12V 2.0 power supplies connect with a 24-pin connector.
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.
Do all power supplies have the same connectors?
No, they’re not always compatible, not even between models from same company. If you already have cables from another power supply and the connectors seem to fit, best you could do would be to grab a multimeter and check the voltages on each pin to make sure you have the same voltages as the ones on an original cable.
What are the 3 most important parts of a motherboard?
These key components include the CPU itself, the main memory, the secondary cache, and any devices situated on the buses. A chipset also controls data flow to and from hard disks and other devices connected to the IDE channels.
What is GND on motherboard?
The System panel cables, as shown in the picture are two wire cables that are color-coded to help identify where they connect to the motherboard system panel connector. The black or white wire is the GND (ground) wire and the colored wire is the powered wire.
Can CPU work without motherboard?
The answer is neither a definitive yes nor a no. The main thing you need to remember when trying to test your motherboard without a CPU is that it is not going to get beyond POST (power-on self-test) without one (although certain recent motherboards are capable of BIOS updates without being connected to a CPU).
What is a ATX power connector?
ATX power connectors are designed to connect a computer’s power supply to an ATX motherboard. They are constructed of metal pins laid throughout a nylon matrix. … The ATX power connector also offers another benefit. Unlike older power connectors , the ATX power connector is designed to only be plugged in one orientation.
