When setting up a computer, most people think about the monitor, keyboard, or mouse first. But none of these devices can even work without one basic part—the power cable. If you have ever looked at the back of your desktop PC, you’ll see a thick black cable going into the power supply unit. That’s the lifeline of your computer. But what is this standard PC power cable actually called?
Why knowing the correct cable name matters
Many people don’t know the proper name of their PC power cable. They just call it the “computer cord” or “the plug.” While that works in daily conversation, it can be confusing when buying a replacement. Calling it by its proper name makes it easier to search, shop, and ensure you get the right cable that fits your system safely.
Exact Answer: What is a standard PC power cable called?
The standard PC power cable is called a C13 AC power cord. This is the universal cable used to connect a desktop computer or monitor to a wall socket. On one side, it has a connector shaped with three small square holes in a row that plug into the back of the power supply. On the other side, it has the plug that matches your country’s wall outlet. This type of cord is common worldwide and is the safe choice for most PCs.
What does a C13 AC power cord look like?
The C13 AC power cord has a flat rectangular end with three slots. That connects to your PC’s power supply unit, also known as the PSU. The other side changes based on the country you live in. For example, in the US, it has flat blades. In the UK, it has a large three-pin style. But no matter where you are, the device side remains the same C13 connector.
Why is it so common?
The C13 power cord became a standard because it is safe, durable, and works for many devices beyond PCs. It’s also widely recognized, which makes replacement easy. Monitors, servers, and even printers often use the same type of cord. Instead of companies designing multiple cords, the C13 standard works almost everywhere.
The role of the power supply unit
Your power supply takes the electricity from your wall outlet and converts it into energy your computer can use. The job of the C13 AC power cord is simply to carry that energy safely from the wall to the power supply. Without it, the PSU doesn’t get power, and your system won’t turn on. A good quality cord ensures smooth, safe delivery without overheating.
Do all PCs use the same C13 cord?
For most desktop towers, yes—it’s the same C13 connector. However, laptops usually use smaller power adapters with different shapes. Some tiny mini-PCs may use figure-eight style or an external brick. But if you have a standard desktop, the answer is almost always the C13 AC power cord.
When to use a 90 degree plug adapter
Sometimes your computer case sits close to a wall, and a normal straight cord sticks out too much. This bends the cord over time, which can wear it down. A 90 degree plug adapter fixes this problem easily. It bends the cord at a neat right angle, so it runs down or sideways instead of sticking out. This is especially useful for desk areas with little space.
Things to look for in a good power cord
Not all cords are the same. Even if they look similar, quality matters. A good cord should feel thick, with strong insulation. It should list its voltage and amperage rating to show it can handle the power load. Pairing your PSU with a solid C13 AC power cord ensures safety and longer life. Avoid flimsy no-name cords that may overheat.
Cable length considerations
Cords come in different lengths. Short ones keep cables tidy in small desk setups, while longer cords are useful if your PC sits far from the outlet. Don’t go too long, though, as extra length can create clutter. If your outlet is close, stick with a shorter C13 cable for a clean setup.
Do gaming PCs need special cords?
Not really. Even powerful gaming computers use the same C13 AC power cord. What matters more is the power supply inside your PC and its wattage rating. The cord itself remains the same. However, in gaming setups where the back of the desk is tight, a 90 degree plug adapter can make cable management easier and safer.
Safety habits when using power cords
Follow these easy safety tips: Always plug and unplug your power cord by the connector, not by pulling the wire. Don’t run the cable under rugs or furniture where it can get crushed. Never use a damaged cord; replace it at once with a proper C13 cable. If your setup presses too tightly against a wall, use a 90 degree plug adapter for safer cable positioning.
Signs it’s time to replace your cord
You should replace your cord if you notice cracks, burn marks, or a loose connection. Also replace it if your PC loses power when the cord moves, as this means the internal wires may be broken. Since cords are inexpensive, replacing them quickly is always safer than waiting for an accident.
Common mistakes to avoid
Many users make the mistake of using any cord that fits, but not all cords have the right ratings. Others forget to check cord quality, assuming all look the same. Some push desks too close to walls, bending the cord sharply instead of using a 90 degree plug adapter. Avoiding these mistakes keeps your PC safe and powered reliably.
Final thoughts
So, what is a standard PC power cable called? The clear answer is the C13 AC power cord. It’s the trusted, common choice for most desktop computers worldwide. Whether you’re replacing a lost cable or just want to be sure about its name, now you know what to ask for. If you face space problems at the back of your setup, add a 90 degree plug adapter to keep things tidy and stress-free. The right cord may look like a small detail, but it ensures your PC runs safely and smoothly every day.
