Introduction of Power supply for pc

The power supply unit (PSU) is an essential component of a personal computer (PC). Its main function is to convert the alternating current (AC) power from the wall outlet into direct current (DC) power that the computer's components can use. The PSU is responsible for providing the appropriate amount of power to each component, ensuring they operate correctly and safely.


There are several types of power supply units available for PCs, with the most common type being the ATX power supply. These power supplies come in different wattage ratings and can be either modular or non-modular. Modular PSUs allow users to only use the cables they need, while non-modular PSUs have all the cables built-in.

The 3 types of power supply for PC

ATX Power Supply: 

The ATX power supply is the most common type of PSU used in desktop PCs. It is designed to be used with ATX form factor motherboards, which are the most popular type of motherboard in desktop PCs. ATX power supplies typically provide several connectors, including a 24-pin main connector for the motherboard, a 4/8-pin CPU connector, and multiple SATA, PCIe, and peripheral connectors for other components. They come in different wattage ratings, ranging from 300W to over 1000W, and can be either modular or non-modular.

SFX Power Supply: 

The SFX power supply is a smaller version of the ATX power supply. It is designed for use in smaller form factor cases, such as Mini-ITX and Micro-ATX. SFX power supplies are usually rated at 300W to 750W and have a smaller physical footprint than ATX power supplies, making them ideal for compact cases where space is at a premium. They usually come with a 24-pin main connector, a 4/8-pin CPU connector, and one or two PCIe connectors for graphics cards, as well as a few SATA and peripheral connectors.

TFX Power Supply: 

The TFX power supply is even smaller than the SFX power supply and is used in ultra-compact desktops and home theater PCs. They are rated between 200W to 400W and have a very small physical footprint. TFX power supplies usually come with a 24-pin main connector, a 4-pin CPU connector, and one or two SATA and peripheral connectors. They are designed to provide enough power for low-power components such as integrated graphics and small hard drives.


When selecting a power supply for PC, it's important to choose a model that can provide enough power for all of your components, taking into account their wattage requirements. It's also important to choose a reputable brand and model that has good reviews and comes with a warranty.

Can I upgrade my power supply to a higher wattage?

Yes, you can upgrade your power supply to a higher wattage. In fact, upgrading your power supply can be necessary if you plan to add more components to your computer, such as a high-end graphics card, or if you want to overclock your CPU or GPU.


When upgrading your power supply, it's important to choose a model that provides enough power for your current and future needs, while also being compatible with your computer's components and form factor. You can use an online power supply calculator to estimate how much wattage your computer will require based on the components you plan to use.


It's also important to choose a reputable brand and model that has good reviews and comes with a warranty. A higher wattage power supply will typically be physically larger than a lower wattage power supply, so you'll need to make sure it will fit in your computer's case. Finally, when installing a new power supply, make sure to follow the manufacturer's instructions carefully and take appropriate safety precautions.
