Wall mount power supplies can be either AC or DC. They come in a range of configurations, depending on the scenario that they’re designed for.
Regulated – Regulated wall mount power supplies feature voltage regulators that ensure the output voltage remains consistent, never deviating from the rated value of the power supply.
Unregulated – Unregulated wall mount power supplies differ in that their output voltage will decrease as the output current increases and vice versa. This means that the power supply must be matched as closely as possible to the voltage and current requirements of the device in question.
Linear – Linear wall mount power supplies convert high-voltage AC into low voltage, which is then converted into DC voltage. Whilst these tend to have low efficiency, they are also more reliable and faster than switching mode power supplies.
Switching mode power supplies – Wall mount switching mode power supplies convert the input signal into DC before stepping down or up the voltage to the required level. These power supplies have high efficiency and are less bulky than their linear counterparts.

Depending on its configuration, a wall-mount power supply will typically consist of a transformer, a rectifier, smoothing, a regulator, and a load. The input transformer steps down the AC power, and a rectifier circuit converts the AC components present into DC components. The signal is then smoothed out by a filtering circuit. A regulator controls the voltage to the desired level, before leading to the load which uses the pure DC output from the regulated output.

Wall mount power supplies are used in a wide range of industries and applications. They can be designed for use with a full range of input voltages and can output to a similarly wide range of wattages. Linear wall mount power supplies are typically used in audio frequency applications due to their immunity to RFI. Meanwhile, wall mount switch mode power supplies are used in phone chargers and DC motors.

In order to choose the right wall mount power supply for your requirements, you need to first find out where your device needs AC or DC. You’ll usually find the power requirement on the device itself, look for the voltage requirements so that you can ensure you are providing the correct amount of power. Too much or too little power may lead to your device being damaged.

Basically, if it's just a cable (no power adapter) and it physically fits your computer, it'll be just fine. Desktop computers (and many monitors) all use the same connector (IEC). Of course, different plugs are used in different countries, but electrically they are all the same.
-
It's tempting to buy just any power supply to run your PC, but that's not a wise choice. A power supply that doesn't provide reliable or clean power can cause any number of problems, including instability that can be hard to pin down.
-
AC adapter, also called a power adapter or laptop charger, is used to provide sufficient power to operate the laptop for extended periods and to recharge the laptop battery.
-
Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
-
The right AC adapter for your device is one with matching electrical ratings. The device's input voltage and current must match the adapter's output voltage and current. Check the device's product label or user manual to see its rated voltage and current.
-
Using the wrong power adapter can lead to various issues such as voltage and current mismatches, overheating, and potential short circuits. This can result in damage to the device, the adapter, or even pose safety hazards like fires. It's crucial to use the correct adapter specified by the device manufacturer to ensure safe and proper operation.
-
Power adapters can fail due to overloading, voltage spikes, physical damage, poor quality components, heat buildup, manufacturing defects, and age/wear. To extend their lifespan, use them within specified limits, protect them from damage, and opt for quality products from reputable manufacturers.
-
Power adapters can cost hundreds of dollars to replace, but they can often be repaired for free if you already have the necessary materials. The same thing can happen to the plug on any kind of power adapter, but it happens most frequently with notebook computer power supplies, especially ones with coaxial cords.
-
Replace your desktop power supply if it shows signs of failure like frequent crashes or overheating, when upgrading components, with age, for unreliable performance, if it's making unusual noises, or if there's physical damage. Regular maintenance helps catch issues early.
-
To test your desktop power supply, you can use a power supply tester, a multimeter, or perform a paperclip test. These methods help determine if the power supply is functioning correctly.

A USB-C power adapter is a type of power adapter that utilizes the USB Type-C connector to provide power to various devices. It delivers power to devices such as smartphones, tablets, laptops, and other electronics that support USB-C charging. These adapters typically offer faster charging speeds and higher power output compared to older USB-A adapters. They are versatile and widely used due to the USB-C connector's reversible design and ability to carry both power and data signals.
-
A USB-C power adapter is used to provide power to various devices, such as smartphones, tablets, laptops, and other electronics that support USB-C charging. It enables users to charge their devices quickly and efficiently by delivering power through the USB Type-C connector. Additionally, USB-C power adapters are versatile and can charge multiple types of devices, making them a popular choice for modern electronics.
-
A 20W USB-C power adapter delivers power at a rate of 20 watts. The charging speed provided by a 20W adapter can vary depending on the device being charged. Generally, it can charge smartphones and smaller devices relatively quickly, especially those that support fast charging protocols. However, for larger devices like tablets or laptops, the charging speed may be slower compared to higher-wattage adapters.
-
No, not all USB-C power adapters are the same. While they all use the USB-C connector to deliver power, they can vary in terms of power output, charging speed, compatibility with different devices, and additional features like fast charging protocols. Some USB-C power adapters may support higher wattages for faster charging, while others may have specific compatibility with certain devices or charging standards. It's essential to choose a USB-C power adapter that meets the power requirements and charging specifications of your device to ensure optimal performance and compatibility.
-
USB Type-C itself doesn't inherently charge faster than other types of USB connectors like USB Type-A. However, USB-C enables faster charging when paired with power delivery (PD) technology and higher-wattage power adapters. USB-C with Power Delivery can support higher power levels, allowing for faster charging of compatible devices such as smartphones, tablets, and laptops. Additionally, USB-C's reversible design and versatility make it more convenient for users, but its charging speed ultimately depends on the power delivery capability of the charger and the device being charged.
-
The main difference between a 20W and a 30W USB-C power adapter is the amount of power they can deliver. A 20W adapter can provide up to 20 watts of power, while a 30W adapter can deliver up to 30 watts. This means that the 30W adapter has a higher power output capability, allowing it to charge devices at a faster rate compared to the 20W adapter. As a result, devices charged with a 30W adapter may recharge more quickly, especially if they support fast charging protocols and can handle higher power input.
