RX Vega 64 Power Consumption: How Much Power Does The RX Vega 64 Use?

The Radeon RX Vega 64 is the best GPU in the Vega series by AMD, but how does its power consumption match up to its performance and what power supply will you need to support a graphics card like this?

How Many Watts Does The RX Vega 64 Use?

The RX Vega 64 has a TGP or Total Graphics Power of 295 Watts, which is the typical wattage it produces. When gaming you should also hit around 285 Watts. However, when idle the GPU should only produce around 18 Watts of power. (Source.)

The wattage that this card uses can change depending on how powerful your gaming setup is, as well as the types of games and tasks you are doing.

RX Vega 64 GPU with a TGP of 295 and an average of 285 watts when gaming.

For example, if you just use your computer to watch videos and scroll on the internet it will use less power than playing a very graphically intensive game.

Whereas gaming you should experience on average around 285 watts.

Another thing to keep in mind is multi-monitor usage.

If you use more than one monitor expect your graphics card to have a higher idle power consumption.

Typically, with an extra monitor the idle power consumption should increase to more than double that of a single monitor.

In this instance, the Radeon RX Vega 64 graphics card will produce around 25 Watts of power when idle in a dual monitor setup.

This is pretty good.

You know it’s a good idle power consumption when the wattage increases by less than double the original wattage with a single monitor and in this case it increases from 18 watts to 25 watts.

When looking at a GPU’s power consumption, you want to look at the TGP (Total Graphics Power) because this shows the maximum power draw you will usually get when using your GPU for intensive tasks such as gaming.

You might also hear the phrase “TDP” which can be used interchangeably with TGP. The difference is essential in that TDP is the total power consumption of a component, and TGP is the total power consumption of a GPU specifically.

You should also know that the TGP of a GPU is not actually the maximum amount of power a GPU can draw.

The true maximum of the RX Vega 64 is 385 watts. However, this is its peak, and in situations where the power consumption increases by this much it will only hit this peak for a couple of seconds and then come back down to its baseline TGP.

Another way for your GPU to surpass its TGP level is by overclocking your graphics card. When the RX Vega 64 is overclocked it can reach a power consumption level of around 290 watts.

What Power Supply Do I Need to Use For an RX Vega 64?

A 550-watt power supply is a minimum recommendation for the RX Vega 64, but I would recommend you get a 600-650 watt power supply just in case.

When purchasing a power supply for your computer you want to keep in mind that every piece of hardware in your system has a power consumption.

Although not as powerful as a graphics card, all of these little components add up and can exceed the wattage of your PSU very quickly.

That’s why you want to be safe and grab a PSU that has around a 20% increase in extra wattage than you planned for your system.

By doing this you will not only know for sure that your PSU will be able to support powering your whole system but it will also be safe from any power spikes that happen when you are gaming.

If you also want to save on your electricity bill, then you should purchase a power supply that is at least 80 plus Bronze certified, with the best rating being 80 plus Gold certified.

That’s why I would recommend the EVGA SuperNOVA 650 GT, 80 Plus Gold 650W,

EVGA SuperNOVA 650 GT, 80 Plus Gold 650W,

The reason why I would recommend this power supply is that not only is it 80 Plus Gold certified, but it is made by EVGA which is a very trusted and well-known brand when it comes to making reliable PSUs

The first ever power supply I ever bought was made by EVGA and it was very reliable.

Not only that, but you get a 5-year warranty with this PSU so you don’t have to worry about it breaking down on you.

Having a PSU that is 650 watts gives you room to overclock and upgrade any components in the future without the need to upgrade to a new power supply.

Because this power supply is made by EVGA it is very reliable and will last you a long time.

This PSU model specifically, is also fully modular, which means it will create extra space since you only use the cables you need for your computer.

RX Vega 64 Power Consumption Compared to Other GPUs

The GPUs power consumption is compared using TGP. It is essential to know and compare your graphics cards to other similar models because it will help you get a grasp on the amount of power your system is going to use.

Here is a comparison of a few graphics cards that are around the performance range of the RX Vega 64.

GTX 1080150 Watts
RX Vega 64295 Watts
RX 5700185 Watts
RX Vega 56210 Watts

What you can tell from this table is that AMDs Vega GPUs have a very high power draw in their respective performance ranges. Even though these cards especially the RX Vega 64 have the decent performance they consume a lot more power than other GPUs in there same category.

For example, The RX Vega 64 produces around the same performance as the GTX 1080 which used to be one of the best GPUs in the market, but the RX Vega 64 uses more than 100 watts than the GTX 1080.

Then, when we compare the Vega 64 to the RX 5700 we can see that there is a 110-watt difference between these GPUs.

This is a very big difference especially when you consider that the RX 5700 is a slightly more powerful card than the RX Vega 64.

What to take away from this comparison is that the higher a GPUs power consumption doesn’t necessarily mean better the performance.

If you want to compare more graphics cards on their power consumption and TGP I have provided a database where you can look at dozens of different GPUs and their power consumption, that way you don’t have to do the research yourself.

Check out the Database.

I have also provided the average power consumption when gaming, as well as the average power consumption when idle, that way you can get a better understanding.
