What Type of Power Supply Do I Need For GTX 1080 Ti?

When it comes to choosing a power supply, it is crucial to make the right decision, especially for a graphics card like the GTX 1080 Ti. An incompatible power supply can cause many problems and result in wasting your money. To use your system to its maximum efficiency and in a trouble-free manner, here are certain features you should pay attention to when getting power supply for your GTX 1080 Ti.  

Type of Power Supply

A GTX 1080 Ti is one of the best graphic cards and therefore requires a great power supply as well. Non-modular power supplies are hence not recommended for this graphic card. And a highly efficient and Gold certified power supply would help you use your graphic card to the best of its ability.


It is stated that a minimum of 600W or greater power supply is required for the GTX 1080 Ti. A six-pin and an eight-pin PCI Express supplementary power connector is also essential. The compatibility of the graphic card with the power supply is of utmost priority.


The efficiency of a power supply is rated and ranked through a particular method. The higher the efficiency, the greater the rating. An 80+ Gold, Platinum, or Titanium rating is usually preferred for the GTX 1080 Ti. 

What Are the GTX 1080 Ti Power Requirements?

When you have narrowed down the type of power you need, it is important to look at other factors that suit your requirements. Usually, the GTX 1080 Ti graphic card requires a power supply of about 500- 600W or higher as well as a six-pin and an eight-pin PCI Express supplementary power connector. Apart from that, make sure the power supply is compatible with your system.

Are Power Supplies Universal?

There isn’t any power supply that is made for universal use. However, the quality can be figured out through some guidelines.

Power supplies differ in their quality; their capacitor sizes can be variant, and chokes and other internal components may also vary. The heat sink can also dissipate heat at different levels, and the larger they are, the heavier the power supply weighs. 

One of the most important features to note in a power supply is that the connector is compatible with the device or system you want to connect it to. Some examples include the 20+4 pin and the 6+2 pin connectors. 

It is important to purchase good-quality power supplies from reputable manufacturers; be sure to note the efficiency, power output, and rails. 

When is it Time to Replace My GTX 1080 Ti Power Supply? 

How often or when to replace your power supply depends on how often you use the system. For a home PC, which is being used occasionally for gaming, you could change it every five to eight years. 

On other occasions, for example, if the existing power supply is faulty, or when you are upgrading to a new graphics card (meaning a more powerful power supply is needed), changing the power supply is recommended. 

How Do I Know if My Power Supply is Going Bad?

When your power supply is going bad, you may notice your computer crashes too often, there are noises coming from the PCU case, or a random blue screen appears occasionally. 

How to Test a Power Supply

To test a power supply, first ensure the switch for the power supply is turned on, and the power cable is secure. Try another power cable to eliminate the possibility of a faulty cable. Check internal PC connections. Remove any external connections to your computer, apart from the graphics card and boot drive.

How to Choose a Power Supply For a GTX 1080 Ti

There are several different kinds of power supplies, with differing features and qualities. Let’s go over some of these to help you make your choice. 

Types of Power Supplies

Power supplies can either be non-modular, semi-modular, or fully modular. The names speak for themselves. 

Non-modular power supplies are quite inexpensive as they do not offer many flexible options to the customer. The cables are attached to the power supply and cannot be detached. Therefore, you cannot add or remove cables according to your choice. Cable management is also a tedious task. They are not recommended for high-end graphics cards like the GTX 1080 Ti.

Semi-modular power supplies have cables for both the motherboard and any graphics card. It also has optional cables, three peripheral slots, and a PCIe power connector slot if the graphic card needs more than an eight-pin power. 

Semi-modular power supplies are compatible with most systems since they aren’t too expensive and are easy to use.

Fully modular power supplies are made for users who need to customize their cables completely. Therefore, this type is the most expensive. 

Corsair CX Series CP-9020103-NA


Power supplies are ranked based on their efficiency, as listed below:

  • 80% efficiency: 80+ White

  • 85% efficiency: 80+ Bronze

  • 88% efficiency: 80+ Silver

  • 90% efficiency: 80+ Gold

  • 92% efficiency: 80+ Platinum

  • 94% efficiency: 80+ Titanium

The higher the efficiency, the more the rating, but you need not go for the power supply ranked highest. You can have perfectly great power with any of these; it just depends on your requirements.
