Also, it is manufactured around an innovative internal design that offers high-end performance, extremely stable voltages, ultra-low electrical noise. It has a 92mm fan that plays a vital role in improved performance and reduced noise. 

It has the ZERO RPM FAN MODE, which means that the cooling fan won’t spin at low to medium loads until you need it to give extremely silent operation. 

What’s next is that it comes with individually sleeved modular cables.

What we didn’t like

As compared to other 600W Power supplies, the Corsair SF600 Platinum is expensive, but it shouldn’t be an issue if you’re a fan of top performance and money isn’t an issue for you. Another thing is that it doesn’t come with the SFX-to-ATX adapter, although it has the bracket for it.

Buyer’s Guide

In order to get the best PSU for your GPU, you’d need to look for a couple of things in it and take multiple things into considerations that are mentioned below.

Ignoring these things will lead to a PSU that wouldn’t work up to what you’ll expect. Also, it will create problems in the future for you and can, severely, damage your GPU as well.


Quality is something that should never be overlooked as ignoring it can lead you to counter a ton of problems in your life. 

If you opt to save money and go for a cheap PSU then it might save you some bucks in short term, but it can cost you a lot in the long run by damaging your PC’s component and making you invest a lot more than what you were supposed to if you had picked a top-quality PSU. 

A quality PSU can give a long-lasting life to your computer, so we recommend you to do your homework before going to buy one. 


Another important thing that should be taken into consideration is the wattage of the PSU that your system requires. It is really necessary to look at the wattage of the power supply as not every wattage of PSU can fit your PC’s requirement. 

This is kind of a situation where more is always not the best. However, a PSU is able to provide enough power under heavy load to all of the components.

Furthermore, the majority of the PSUs hit their peak efficiency from 40% to 80% of the power supply’s max capacity. And we recommend building to about 60% of a PSU’s capacity to be in the sweet spot for efficiency and leaving enough room for future upgrades.


The efficiency of a power supply is very important because a higher-efficiency one tends to give better performance, generating less heat, and wasting less power; making the PSU make less fan noise. 

A PSU that has an efficiency rating of 80% gives 80 percent of its rated watt in the form of power to the system and loses the other 20 percent as heat. Furthermore, there are several tiers of 80+ ratings that include bronze, silver, gold, and platinum; and the PSUs have been divided into these tiers due to their performance and other aspects. 

Cable Management

If you’re a fan of aesthetics then you won’t be pleased to see your PSU carry the huge stack of unused cables and struggling to hide them inside the case, which later on can be interfering with the airflow in smaller cases. 

We would recommend the modular PSU for GTX 1080 because they are the popular ones in the market; allowing you to effortlessly organize your power connections, and have many pros as compared to the standard ones. 

Trusted Brands

A PSU from a trusted and widely known brand can give you a lot more great performance than the local and cheap quality ones. It is not always good to save money when you’re prone to get something fishy that drives you to damage yourself in the future. 

We suggest going for a branded power supply as they are more trusted and offer the performance that you expect. 

Also, trusted brands give a warranty so if you run into any issue, they will help you out with that. 


After going through this guide, you’ll be able to make proper decisions before buying a power supply for your GTX 1080 to enhance the performance and experience. 

It’s really important to look for a powerful PSU that really delivers what it promises because it plays a huge role in your PC. Not every power supply matches your system; neither a random picked one can fit and deliver as you expect. 

If you’ve found what you were looking for, do let us know about your input in the comment section as well.


To be more precise, a PSU with at least 550w would work fine. However, a 500w one works too, but to make your GPU worthwhile and to save it from being damaged, 550w, or above is always recommended.

We wouldn’t recommend going for 450w PSU for GTX 1080 as the GPU requires more energy to properly work and execute. However, a 500w would be pretty enough for it, but for safety precautions, a PSU with at least 550w would be an ideal candidate for the GTX 1080.

To be honest, we cannot say that it is the ultimate KING as it was back in 2016, but it is still a better competitor and a great option for 1080p 144Hz or 1440p 60Hz for new games and runs smoothly the older games at up to 4K resolution.

It all comes down to your budget, but if you’re building a gaming pc then you wouldn’t want it to be destroyed or damaged in a couple of days right after building. A cheap PSU can damage the GPU and other components in your system, so it is NOT recommended to opt for a cheap PSU. You can wait till you can afford to buy a decent one.

There are a few brands that make the best PSUs in the market. Opting for a well-known brand would really be an appreciated decision as widely known brands won’t take a single step to ruin their reputation; so a branded PSU will give you a huge performance difference if compared to a local one.
