Best PSU For 3080

The RTX 3080 is a new generation graphics card that is set to become one of the best options in its range, due to its excellent performance ratio. It is confusing and people want to know what power supply we need to move with the  RTX 3080 graphics cards.

Keep in mind is that the RTX 3080 is a very powerful graphics card. It far outstrips the RTX 2080, and also has a huge advantage over the RTX 2080 Ti.

However, most of the current games do not optimally use more than four cores and eight threads, which means that we will not need a processor with a high multithreaded capacity to get a good experience.

With the transition that video game developments will experience after the arrival of the next-generation consoles, there will be a significant leap in terms of the use of multi-threaded CPUs, but the GPU will continue to be the most important component, especially at high resolutions of 1440p and higher.

So for the perfect performance of a system to operate on merit, it always needs an excellent power supply to provide power that should stand cooler and not burst during complex and heavy calculations.

Choosing a suitable power supply for our equipment is a vital issue both when buying a new machine and when trying to update it.

When choosing a power supply, we must also look at its appearance and weight. Although it is not a determining factor, a high weight means that the source incorporates large heatsinks that help to cool it

As you probably guessed from the name, this 1200W PSU is completely overpowered for most people. In fact, this is most likely not the most practical PSU on this list. However, if you really need that kind of power, you can get it. Seriously, the EVGA SuperNova 1200W PSU is absolute power.

EVGA Supernova 1200 P2 has a reliable 1200W output. Its efficiency is 80+ platinum, so you don’t need to worry about reliability. A popular feature in power supplies is the zero-speed mode.

EVGA has this as well, but it is known as ECO mode. Just be aware that the fan curve is a bit limiting. When you need extra juice, the fan will turn on in a minute or two. Fortunately, this is an efficient power source, so you can turn ECO mode off.

This power supply is fully modular. Subsequently, this means that you can remove unnecessary cables. We always value a great fully modular PSU. The fact that the included cables have black braids and are made of high-quality materials makes it even better.

Also worth mentioning is the quiet operation and of course the 100% Japanese capacitors. The standard fan size is 140mm, it uses double ball bearings. The 10-year warranty is undoubtedly the icing on the cake.

4. Corsair SF 750 Watt Power Supply


Brand Corsair
Wattage 750 Watts
Form Factor SFX
Power Supply Design Fully Modular
Item Weight 1.98 Pounds
Fan Size 140 Millimeters

Buy on Amazon

  • Ensures ultra-high efficiency operation for less excess heat and lower operating costs.
  • Delivers powerful cooling with a Low-Noise operation.
  • Allows installation into both small form Factor and ATX cases.

Corsair takes another spot on this list with something slightly different. Each PSU we’ve talked about is a standard ATX size. As the name suggests, the SF750 is an SFX power supply.

Some also refer to it as a small form factor power supply or SFF. In short, this is one of the few small PSUs that we can recommend for the RTX 3080 and 3090.

The SF series turns out to be one of the best choices when it comes to small form factor PSUs. The SF750 is actually an A-level power supply. Rest assured, this is one of the most reliable SFX power supplies ever made.

It is 80+ Platinum certified, which is always great to see. This is especially true for SFX PSUs as you will appreciate all the reliability you can get.

SFX PSUs often suffer from coil whine, but Corsair has managed to fix it. Of course, under full load, this can become noticeable.

However, this is one of the few PSUs that have so much power in it, so we just need to get over it for now. The capacitors are purely Japanese and very reliable.

As usual, there is something to worry about. Putting this PSU in a small case with the 3090 will surely raise the temperature.

The bigger issue is how much premium you usually pay for a high-quality SFX PSU. It’s the same with the SF750.

5. Cooler Master MasterWatt 750 Watt Power Supply

  • Zero RPM fan mode for near-silent operation at low to medium workloads.
  • Fully modular cables, so you can only connect the cables your system needs.

The Corsair RM750X is the perfect PSU. It has all the premium features you’d expect, but the overall value is what earns it a spot on this list.

The CX, CMX, and RMX series power supplies are much better than the VS series. To validate this point, First, this device is 80+ gold certified.

It features low power consumption, better acoustic performance, and lower temperatures. It is tuned for quiet operation at full load. However, it’s still slightly louder than the more expensive PSUs on this list.

As usual, the popular Zero RPM fan mode is built into this PSU. Industrial-grade capacitors are Japanese-made and we trust Corsair for their reliability.

The cables are completely modular, so you can get rid of unnecessary cables. Overall, this is a great power supply.

However, while 750W is sufficient for most people, we recommend going further if you are an enthusiast. As soon as you start adding capture cards, additional solid-state drives, and other components, power consumption can start to rise.

Power Supply Unit


Having a suitable power supply for your PC can both allow and undo its configuration. Without enough power, your PC cannot function at its best. You could waste money on expensive upgrades if your personal computer can’t provide enough power!

However, in the same way, focusing too much on power is just as inefficient. While it shouldn’t affect how your PC runs, you could end up wasting a lot more money than you need. Different PSUs supply different amounts of power, and they also incorporate different features.

While it is difficult to filter the best power supply due to a large number of models, this buying guide will provide as much information as possible for the buyer.


The efficiency rating on your PSU is also something to consider. While non-modular units tend to be less efficient overall, most come with their own efficiency rating.

The most common indicator for this is the 80PLUS indicator, which is present in all units that operate with an energy efficiency greater than 80%.

Most PSUs can’t give you a specific number on how efficiently they operate, but the 80PLUS rating comes in several tiers that give you a better idea of ​​actual efficiency.

Those that are not 80PLUS certified are the lowest level and include all units that do not meet this standard. From there with this certification, white is the lowest level, and then comes Bronze, Silver, Gold, Platinum, and Titanium.

The efficiency of Gold is the sweet spot for most video game players, as Platinum and Titanium can sometimes be excessive for computer applications. However, any feature with the 80PLUS rating is a great option to start with, and the higher the score, the longer the future life it will have.


The modularity of the power supply is an important decision when making the purchase. While the PSU will perform the same basic functions, regardless of how modular it is, it can change in price, cable management, performance, and more.

Modularity in power supplies refers to how customizable the cable outputs are on the unit. They range from fully modular to non-modular. The fully modular ones have ports for all cables that can be removed and swapped at will.

This means that if you are trying to create a specific color scheme with your PC, you can add colored cables in particular shades to match that particular theme. You can also swap out more expensive cables, such as those with nylon sleeves instead of plastic.

On the other hand, because these units are so customizable, they tend to be more expensive. However, they also tend to work better.

Because you only connect the cables you need, therefore, there are no power-wasting cables in the unit. Airflow and performance tend to be better too, as you won’t have extra cables taking up extra space.

At the opposite end of the spectrum are non-modular power supplies. These power supply units come with all the cables you could possibly need permanently connected to the unit.

For someone who plans to make use of all these cables, it serves its purpose without a problem, but for others, it makes cable management a nightmare.

Also, having all these extra cables can negatively affect performance. As we mentioned, too many unused cables can waste power, and if they’re in the ventilation stream, they can also cause the unit to heat up unnecessarily.

In the middle are the semi-modular fonts. These drives have multiple ports with interchangeable cables, but the essential ones, like the power line, remain permanently connected to the drive.

In general, semi-modular units are the best cost-performance ratio, but if for example, the power line goes bad, you cannot repair the unit as easily as you would a fully modular unit.

Stabilization of different lines provided by a power supply

Low-quality power supplies only have a common stabilizer for the three lines 3.3v, 5v, and 12v, which causes an imbalance in the voltages of these lines when pulling only one line.

Ideally, power supplies should incorporate three different stabilizers: one for each line. What this does is make the product more expensive, in addition to the fact that there are not many power supplies on the market that have this independent stabilization.

Residual ripple or fluctuations

In theory, the power supplies should supply a perfectly continuous current; In practice, there is a residual ripple at high frequency, called noise or ripple. This ripple is harmful to electronic equipment, so it must be reduced to the maximum.

This characteristic refers to the noise that is produced in the output direct current when the alternating current is transformed. According to ATX specifications, this value cannot exceed 120mv for the 12v line and 50mv for the 3.3v line.

Even so, it is preferable that this value is smaller than that indicated by ATX since this extends the useful life of our components. For example, the ATX standard foresees 120mV max at full load at + 12V voltage, but in the best sources, this value is 30mV. An oscilloscope is used to measure the fluctuation.

Noise pollution

Some power supplies are silent even when loaded, but others are not.

The best in terms of noise level is to stay below 45dB and sources that exceed 50dB in load should be avoided. We must also bear in mind that a source with an exact power for your equipment will make the fan work at full power to cool it all the time, so noise pollution will be high all the time if we do not monitor with the dB specifications of the power supply.

When choosing a power supply, we must also look at its appearance and weight. Although it is not a determining factor, a high weight means that the source incorporates large heatsinks that help to cool it.

It is important to analyze the label which indicates the current values ​​that the power supply in question is capable of supplying. In reality, these values ​​are usually somewhat lower than those indicated on this label. What matters is not how many watts you put in, but whether these watts are real.


Choosing a suitable power supply for our equipment is a vital issue both when buying a new machine and when trying to update it. It is advisable to resort to recognized brands and choose a PSU that meets the power requirements of our equipment, in addition to the brand, when choosing power supplies the 80 Plus certifications will also help us. Keep in mind all the above factors while selecting one to buy.

It also doesn’t hurt to think of a capacity that is capable of supporting some other additional device. So after this, which font will you choose?
