How Many Amps Does a Gaming PC Use?

Do you know how many amps does a gaming PC use? You may be surprised to learn that it can draw quite a bit of power, depending on the make and model. So, what’s the big deal?

Well, if your PC is drawing too much power for the size of your electrical panel or circuit breaker, you could end up with blown fuses or a tripped breaker.

Not only is this an inconvenience, but it could also be dangerous. Read on to learn more about how to calculate the amps your gaming PC draws and how to protect your home from potential harm.

How Many Amps Does a Gaming PC Use?

A typical gaming PC uses between 300 and 600 watts. That’s between 2.5 and 5 amps at 120 volts. A lot of that power goes into the graphics card, which can use 150 watts or more.

The processor also uses a lot of power, and gaming laptops tend to have high-powered processors that use even more power. So if you’re playing games on a laptop, it’s not uncommon to see it drawing 5 or 6 amps.

The bottom line is that gaming PCs use a lot of power, and if you’re not careful, they can easily trip a circuit breaker.

That’s why it’s important to make sure your gaming PC is plugged into a surge protector. And if you’re ever in doubt, it’s always better to err on the side of caution and unplug your PC before you start playing games.

How many amps does a PC power supply put out?

A power supply is responsible for supplying power to all the different parts of your computer. Specifically, it provides power to the motherboard, which then distributes power to all the other components.

The amount of power a power supply can provide is measured in amps. Most modern power supplies must output at least 18 amps on the +12V rail in order to work with a mainstream computer.

If you have a system with a single enthusiast-class graphics card, you’ll need a power supply that can output at least 24 amps. And if you have a high-end SLI/CrossFire system, you’ll need a power supply that can output at least 34 amps.

So, when choosing a power supply for your computer, be sure to check how many amps it can provide on the +12V rail.

How much power does a gaming PC require?

A gaming pc requires a lot of power to run efficiently. The average gaming pc consumes 250-400W/hour. However, with every hardware installed, the configuration can change, altering the power usage capacity of a gaming PC.
