Gtx 1080 power supply recommendation: Reddit — Dive into anything

What is the Power supply recommended for gtx 1080?

Choosing a power supply from a bunch of brands to your gtx 1080 graphics card can be a tough task especially when you are not a professional in this sector. So you just need to get knowledge about what power supply will be suitable with gtx 1080. Some power supply may providing definite watts but actually it won’t. In most cases, you must choose a power supply with certified stamps.

The Geforce GTX 1080 is one of the most popular and good services providing GPU will give you maximum productive tasks while working. By the way, when you tend to work with your gtx 1080 graphics card, you must consider whether the electric power supply is sufficient or what you provide to your pc to run is any certified power supply or not.

To know what power supply is recommended for Geforce GTX 1080, you must consider other related components usually used with it. Here you will know the basic requirements and subjective way to cover up how many watts you need to run smoothly and safely. We’ll also cover up the efficiency of the power supply which suits the GTX 1080. Let’s get started-

Considering other PC components

While you are operating a PC, the power supply not only powers up the graphics card but also imparts on other pc components. Though the task happened simultaneously so you must keep considering all of the components and finally, you may get to know how many watts the power supply will be suited for your PC.

Nowadays the several brands provide different quality power supplies, most of them come with specification wise or component recommended wise like suited motherboard, processor or graphics card, etc. So if you delicately choose any power supply from the market without researching your PC components, you may fail to select a good one. So what you need to consider is given below-


Generally, the GTX 1080 GPU takes around 180Watt of frequent power supply. While after having this power supply all other components take their energy from the Power supply unit. So you must calculate the whole wattage and will get a decision on what wattage power supply unit you need to insert. 

Processor section

The central brain of a PC as a Processor takes 65 to 130 Watts of electric power supply. So the mainstream processor like Intel, Rygen has to give sufficient power efficiency to operate the PC. But what we calculate the total power supply from the processor section is standard for a wide range of models like core i5 to I 9 and Rygen also. If you have a PC with an 8 core or 6 core unlocked Cpu you may need to increase the wattage.

Other Components

The most power-consuming components are CPU and GPU. After all , you must prove the decent and frequent power to other components like motherboard, Hard drive, Solid State Drive (SSD), RAM, Etc.  These components take around 80 to 90 Watts of power. So considering all the components you can manage the wattage that you need for the insertion of your PC.

What is the recommended wattage for gtx 1080?

What we’ve known from the previous section on how much wattage a CPU, GPU, and other computer components takes, Now you can calculate the power for your graphics. As the GTX 1080 can smoothly run with only 180 Watts of electric connection. As well as considering other components it will be the top pick to go with a minimum of 550 Watts of the power supply unit.

This is because what the company claims of the definite wattage they provide is not always right. It may vary in many cases. Although branded and certified power supply can give you utmost energy to your PC but it may fluctuate, what is standard for your GTX 1080 is to take a minimum 550 Watts power supply. But if you want to run the pc safe and tension free the recommended power efficiency must be 650 Watts.

What should you look for a power supply to run gtx 1080?

While you have a decent power supply to run gtx 1080 Graphics, you will consider the best performance from your pc unit, Right? If you previously choose a recommended 650 Watt of power supply, although having issues with those units, what will it look like, awkward? So to know your power supply, you must understand the usability of it.

High-quality build

What you first look back on your power supply is whether it provides good value or has any issues with general use. To make a high-quality build you must consider the branded power supply which will not relate you to any fixation during the computing job.  So to maintain a high-quality build you must choose a power supply that provides you more than enough energy to run the computer smoothly.

Very versatile

Besides high quality and enough power supply, the product should be versatile to use in any sort of task. Without having any issues, the power supply that you choose may not be sufficient to keep its workflow. A versatile, qualities and suitable power supply give you the best experience while working.

More than enough power

If you take a power supply on recommended wattage, you will get enough power to operate the gtx 1080 graphics as well as it runs smoothly to other components.


Your desired power supply must have to produce less noise. The quiet features are important form factors of a good quality power supply.

Superior durability

What we recommended is that the power supply for your graphics must be durable enough to tackle down any situation while operating the pc.

How do you check the efficiency of a power supply?

First of all, whether choosing a power supply you must look at the wattage the pc needs. If you can give more than the recommended wattage it will be efficient for your pc as well as good performance. So at the end of power efficiency, if you choose a power supply of more than recommended wattage it will progress your productive work.

By the way, when you buy a branded PSU, you must check if it is gold-rated or platinum rated and should check the efficiency. But whatever the condition for gtx 1080 you must pick a power supply of more than 80+ rated.


The power supply is the crucial component of your computer. It divided the power into different components. So it must be well suited for your computer whether having decent power and other form factors. If you want to get the high benefits from any power supply especially when you run a gtx 1080 graphics, it must have been gold-rated or at least 80+ efficiency certified. And as a final thought, always try to choose a durable, superior power supply for better performance.

Do you need a new power supply for Nvidia’s GeForce RTX 3080?


It depends on what you’re concerned about.

Do you need to upgrade your power supply for Nvidia’s GeForce RTX 3080 graphics card? That’s a concern many people have, but it’s actually two concerns clumped into one.

Mentioned in this article

GeForce RTX 3080

First, people fear they’ll need a new PSU to handle the new 12-pin connector on Nvidia’s own RTX 3080 Founders Edition. Second, the RTX 3080 pulls more wattage than even the prior-gen RTX 2080 Ti flagship. That’s why Nvidia bumped the recommend power supply rating up to 750 watts to compensate, up from a 650W maximum last go-round.

One of these questions is simple to answer. The other takes some explaining. Let’s dig in.

Do you need a new power supply for the RTX 3080’s 12-pin power?


Brad Chacos/IDG

Nvidia’s 12-pin power connector

Yes, Nvidia created a proprietary new 12-pin power connectors to fit on the shortened custom PCB inside its GeForce RTX 3080 Founders Edition. But the Founders Edition ships with an adapter that converts a pair of 8-pin power cables to the new 12-pin connector. Plug it in and it just works. Note that Nvidia suggests using separate 8-pin connectors plugged into your power supply, rather than using a single PSU cable with a pair of connections daisy-chained on the business end.

That said, if you have a transparent case window and care about aesthetics, Nvidia’s 12-pin adapter looks janky in your case. It’s too short and chunky, and even somewhat blocks the illuminated white “GeForce RTX” logo on the edge of the card. If you don’t like it, some power supply makers such as Seasonic and EVGA will offer full-length 12-pin to 2x 8-pin cables, which you can buy and slip directly into your existing modular PSU.

The short 12-pin adapter plugs into the center of the Founders Edition, in a connector embedded in the card’s fin stack.

No other RTX 3080 graphics cards announced so far feature Nvidia’s 12-pin connector. Everything but the Founders Edition sticks to standard 8-pin connectors.

Do you need a bigger power supply for RTX 3080?


The GeForce RTX 3080 is rated for 350W of total board power, and Nvidia recommends using a 750W power supply with it. That’s a lot more than prior-gen Founders Edition graphics cards required. The GTX 1080 needed only a 500W power supply, while the RTX 2080 and 2080 Ti required a 650W PSU. If you have a power supply under 750W, you’ll probably want to consider upgrading.

All that said, the GeForce RTX 3080 might work if you have a very efficient 650W power supply. We test whole system power draw for our graphics card tests. In a system with a six-core Core i7-8700K, two SSDs, 32GB of fast memory, a liquid CPU cooler, and RGB lights galore, the RTX 3080 Founders Edition maxed out at 482W of total system power draw.

Brad Chacos/IDG

The Nvidia RTX 3080 in our GPU test system.

That’s not a worst-case scenario though. We test power in a GPU-bound game at a GPU-bound 4K resolution to see what happens when the graphics card specifically is pushed to the max. For our games testing, we overclock the 8700K to 5GHz on all cores, which puts its performance on a par with the stock Core i9-10900K, per TechSpot’s benchmarks. With that overclock applied, we saw the system draw between 500W and 550W of total power in some games that hit the CPU hard too, like GTA V and Total War: Troy. Newer systems with more cores pushed under an aggressive overclock could obviously draw more.

A non-modular 80 Plus Bronze 750W PSU

Thermaltake Smart BX1 RGB 750W power supply

Basic number skills tell you that 550W is still under 650W. Depending on the rest of your setup, and how hot it is in your room, you could probably run the RTX 3080 on a 650W power supply. But PSUs differ in how they deliver the wattage advertised on the box. Less efficient power supplies need to draw more energy from your wall socket to hit their rated maximums. An 80 Plus Bronze-rated power supply will convert at least 82 percent of your wall energy to PSU output, with the rest wasted as heat. A pricey 80 Plus Platinum PSU converts 89 to 92 percent of the power it draws from the wall to actual output into your computer, depending on the load.

So what? The less efficient your PSU is, the less reliable it is, and the harder it has to work to convert wall energy to actual power output. A power supply that needs to work harder tends to offer less reliability and longevity than more efficient models. Being in a hot room can also reduce your power supply’s output.


Asus has built a function into its ROG Strix RTX 30-series cards to sense if the PSU is unable to keep up with loads. The LED lights will blink if there is a power sag.

That could be an issue with the increased power demands of the RTX 30-series. Don’t take our word for it–Asus said exactly that while showing off its ROG Strix RTX 3080, which includes sensors on its trio of 8-pin power connectors to show you if they’re getting the energy they need. From our coverage:

“The company said a modern GPU can go from using nearly no power to suddenly spiking to hundreds of watts. That’s something a borderline PSU, or one that’s been driven hard, might not be up to, Asus said. ‘And even if they have a high-power PSU, if it has been run hard for a number of years, its voltage regulation may no longer be adequate to cope with the fast load changes,’ the company added.”

Your power supply isn’t the only concern if you’re buying a GeForce RTX 3080 with just two 8-pin power connectors, like Nvidia’s Founders Edition. The RTX 3080 is rated for 320W of total board power. Each 8-pin power connector can supply 150W of juice, leaving your motherboard’s PCIe slot to pump out the rest. Now, PCIe slots are rated for 75W of power, but less-complex motherboards may struggle to do so, Asus warns.

“This approach is perfectly within spec, but it may create additional power-delivery and thermal demands that some motherboards might not be built for,” the company said—especially if you want to overclock your graphics card. Asus and many other third-party graphics card suppliers have built their higher-end RTX 3080 offerings with a trio of 8-pin power connectors to alleviate the potential issue.

Brad Chacos/IDG

Those are a lot of words to get back where we started. Do you need a bigger power supply for RTX 3080? Definitely maybe. I’d strongly recommend using at least a 750W PSU like Nvidia recommends, especially if you’re using a system that’s full of budget or mainstream parts that have been ridden hard the last few years.

Will I need a new power supply if I upgrade my GPU?

Graphics cards don’t get any less powerful (or power hungry), so if you’re upgrading from an older GPU to a newer model, you might worry that you’ll need to upgrade your PSU as well.

Might be time for a new PSU anyway

Before we dive into the ins and outs of determining whether a new GPU power load will require a new PSU to keep up, let’s throw out the small PSU PSA.

Programs for Windows, mobile applications, games — EVERYTHING is FREE, in our closed telegram channel — Subscribe 🙂

Power supplies do not last forever, and build quality and efficiency increase over time.

Even if you decide to reuse old hardware and simply replace your old GPU with a new one, seriously consider replacing the PSU with it, whether or not it requires more power.

After all, power supplies are the critical infrastructure of a PC, and it would be a shame to finally get your hands on a new GPU after facing oversupply and speculator prices only to have it go up in smoke.

Determining if more power is needed

The key question is not just does the GPU I installed use more power? Key question: «Does my entire build with the addition of the new GPU exceed the recommended level for my current PSU?»

Because if you have a power supply with a significant amount of power, then there is no reason to replace it (other than replacing a really old power supply just in case).

Calculate the current power load

The key to answering our question is how much power all the equipment needed to supply your power supply. We emphasize the word «everything» because to accurately answer your question, you need to consider every single piece of PSU hardware, including everything from extra drives to case fans, not just flashy things like the CPU and GPU. .

If you like, you can apply the long division method to the problem, independently find the estimated power for each piece of equipment and put it all in a spreadsheet.

But why work so hard when we live in the future and there are many handy tools that will do all the hard work for you?

If you want an easy and reasonable estimate of the power requirements of your build, you can go to and «build» your PC by searching for components in your current build. Compare the calculated load with the rating of your current power supply.

If you would like both basic and detailed information about your power supply needs, you can also use the OuterVision Power Supply Calculator. Not only can you use the same «plug-in parts» approach, you can also really dig into Expert mode and tweak the results based on additional options, like the overclocking settings you’ve applied to your CPU and GPU.

For example, we calculated the build with AMD 5800X CPU, GTX 1080 GPU, 32GB RAM, some SSDs and auxiliaries such as fans and the like, and 750W PSU using calculators and got the estimated load power 445 W.

Recalculate with your new GPU

Once you figure out what the current load is on your computer, you can replace the old GPU with the new GPU in your calculations. By the way, you will not always increase the load.

Your new card may be about the same in terms of power requirements or even slightly lower than your old card. Either way, you’ll have a new value to compare against.

However, if you’re going big, like swapping out an old GTX 1080 for an RTX 3090 Ti, don’t be surprised to see a jump in projected load.

When we replaced the GPU in our calculation with a more powerful model, our load calculation jumped to 675W. The 66% load increase isn’t surprising considering the RTX 3090 Ti is a power-hungry card, drawing around 450W compared to the GTX 1080’s average 180W — a 150% increase.

If you think 675 watts is starting to sound like heater territory, you’re not wrong.

Compare current and future stock

If you’ve followed this course so far and done calculations on your hardware like we did, you have two numbers: the estimated power draw for your old build, and your new build with an upgraded GPU.

Now it’s time to talk about margin of safety and risk tolerance. Headroom is how much extra available power is left in the wattage rating of a particular PSU after you have placed it under load. There are some pretty strong opinions about headroom in the PC builder community, including the argument that you should always have around 50% headroom.

It may have once made sense to use a low quality and inefficient power supply with 50% headroom because you couldn’t trust it to actually work as expected. But with today’s high quality, properly certified efficiency PSUs, this is a bit extreme. Even though some PSUs get a small 2-3% efficiency boost at around 50% load, greatly increasing your PSU size just to get a 2% efficiency return might be too much for your budget and needs.

In our initial calculation, we have a 750W PSU with a 445W load. This load is approximately 59%, which gives us a headroom of 41%. That’s a pretty significant wiggle room. You might even argue that if a build is destined to go without any updates, that might even be excessive.

However, replacing the old PSU with an RTX 3090 Ti increases our estimated load to 675W, reducing our wiggle room from 41% to 10%.

This is not ideal and we may run into problems, especially with the computer under heavy load, instability and even crashes. Of course, you can choose not to, and you can even lower the voltage on your card a bit to fix this problem.

But that’s why the manufacturers say an 850W PSU is the minimum for the RTX 3090 Ti, but recommend a 1000W PSU — if we repeat the calculation with a 1000W PSU, we increase this headroom percentage from 10% to ~ 33%.
