How we picked
If the power supply is too low, it will begin to overdraw, and it will eventually damage not only the power supply itself but also the GTX, rendering it unusable in some cases. And if the power supply is too high, sure it will work fine, but you’re essentially wasting power that could be going to another component. Not to mention it will cost you extra money unnecessarily!
Instead, you should be using a power supply with the wattage that is recommended for the GTX 1080 ti specifically. It should be of at least 600W, so a bit over that is usually the ideal option. We’ve compiled a list with our top five power supplies for the GTX 1080 ti, so you can choose the one most suited to you while resting assured that it’s compatible! We have prioritized high quality materials and a range of budgets.

Things To Consider
The GTX 1080 ti is one of the best graphic cards in today’s market that you can possibly use in your gaming setup. It is an essential component for serious gaming, and it provides users with an incredible overall gaming experience. But like all other components in a gaming setup, the GTX 1080 ti needs a suitable source of power, to keep it running smoothly for the best performance possible.
When it comes to finding a suitable power supply, you can’t just go for any. It’s important that the power supply has the right amount of wattage needed for the graphics card, so that you aren’t wasting electricity, and so that you aren’t possibly damaging the components by not having a high enough wattage. For the GTX 1080 ti, it is recommended that you use a power supply with a minimum of 600 watts, so anything above that should be fine. However, going too high above that will just lead to waste, so the ideal is around 650 to 700 watts, or so.
There are plenty of suitable power supplies available, so choosing the best possible one might be tricky, especially considering that they all very much look the same! So let’s look at the main factors that you can take into consideration. And remember that the power supply needs to suit your needs and preferences, and not the other way around!
Wattage
As we’ve mentioned, the GTX 1080 ti requires a minimum of 600 watts, in order for it to perform safely and with a good performance. Going too high above that will just cause you to overpay for electricity, which is less than ideal. So the recommended range of wattage would be somewhere between 600 and 800 watts of power!
Efficiency
When it comes to a power supply, efficiency is key. The higher the efficiency, the better the performance and the smoother and more stable the supply of power will be. Usually, this efficiency will be rated and ranked accordingly, so that you can quickly see how good it is.
For the GTX 1080 ti, you should aim for a power supply that has a rating of 80+ Gold, 80+ Platinum, or 80+ Titanium. Any lower ranking will likely be unable to keep up with the graphics card, and will therefore not be functioning at the best possible capacity.
Fan Cooling System
One of the biggest issues in gaming setups is overheating. With so many components, working at a demanding pace, and at such a high capacity, it is no wonder that the power supplies in use are going at full speed, with the risk of overheating and malfunctioning.
That is why the fan cooling system is one of the most important factors to consider, as it is what will keep the power supply running smoothly and without interruption, and what will protect it from becoming damaged and worn too soon.
Whether it uses intelligent thermal technology or has an auto-adjustable fan speed, it’s important that the fan system is able to detect and accurately prevent overheating.
Design
Although most power supplies pretty much look the same, it’s still important to pay attention to the design, and the different features that it presents. A more compact design is usually better, not only because it will be better to fit into your setup, but also because it will be a lot less prone to overheating. There are also some designs that purposefully situate extra components at the top of the power supply, leaving the bottom less clustered, for an improved airflow that once again helps prevent overheating.
Something we recommend is that you look out for modular or semi-modular designs. With these, you have the ability to only use the cables that are needed, allowing you to store away all other cables, as they can be removed from the power supply. This helps reduce clutter, improves the airflow, and it also saves you space, and makes the setup look a lot better!
Energy-Saving Operation
If you’re in doubt between a certain amount of wattage and another, it is usually best to go for more, rather than less. As it is better to ensure you have enough power than to force the components to struggle and possibly become damaged.
If this is the case, then you should 100% look out for power supplies that have eco-friendly and energy-saving operations, as they will not waste unnecessary electricity, and will therefore reduce operating costs. In fact, this is something to look out for regardless, as it’s always good to save as much money as possible.
NOTE: As the RTX 1080 ti is now an older GPU its price has drastically dropped making it a great budget graphics card choice that still packs a significant punch.
What kind of power supply do I need for a GTX 1080 Ti?
For a GTX 1080 Ti graphics card, you need a power supply of a minimum of 600 watts, preferably a little more than that. Other than that, you should simply ensure that it is fully compatible with your setup and that it has all the necessary features for an efficient and smooth performance.
Are power supplies universal?
No. Although some power supplies are incredibly compatible, there is no singular power supply that is completely universal. This is because different components and setups will require different levels of wattage and different features for their efficient operation. The factors to look out for and consider can be universal, but ultimately, each power supply has to work with each specific component.
When is it time to replace my GTX 1080 Ti power supply?
On average, a power supply for an at-home gaming setup should last you between five to eight years. However, the amount of time a power supply lasts depends on the use that you give it, and on the care you give it.
Ultimately, you should replace the power supply whenever it starts to become faulty, or if it begins to malfunction on a regular basis. You should also replace it if you switch from the GTX 1080 Ti to a different graphics card, as it will then require a different amount of power.
How do I know if my power supply is going bad?
A clear sign of your power supply malfunctioning and going bad is the computer and game crashing often. A random blue screen can also be a sign of this. And of course, if the power supply is operating too loudly, or is causing weird noises, it is almost certainly a sign that it isn’t operating properly, and that something is wrong.
