Best PSU For RTX 4080 Buying Guide

A gaming PC’s power supply is just as crucial as the other parts that give it the performance needed for demanding video games. As a result, you need to be careful while choosing a power supply for your gaming PC. You may have noticed that gaming PCs have a variety of power supply options.

Even if the power supply is of good quality, if you don’t have the right expertise, you could easily end up with a power supply that is inappropriate for your gaming PC. You must select the ideal power supply from the list of those we have chosen as the greatest. The following purchase guide will help you choose the most appropriate power supply for your needs.


The first thing you notice about a power supply device is its output wattage. Power supply units for gaming PCs come in a variety of sizes and output wattages, including 550W, 750W, and 850W. More power can be delivered to the components by increasing the output wattage. However, you must select a power supply based on the amount of electricity you need. A 550W PSU will be adequate if your gaming PC requires about 400W of power.

As a result, you must be aware of your gaming PC’s power needs based on its components. Ideally, a 550W PSU should be sufficient for a cheap gaming PC. A 750W PSU will be sufficient if you have a powerful gaming computer. You must use an 850W and 1000 Watts power supply if your PC has multiple graphics cards. You can, however, maintain some headroom with a greater power supply than necessary for upcoming component upgrades.

Power Supply Design

There are 3 main power supply designs on the market,  These power supply designs come in non-modular, semi-modular, and complete modular varieties. The cable connectors of a non-modular power supply are fixed and cannot be removed. On the other hand, a modular power supply allows you to remove the cable connections as needed.

When you reach a semi-modular power supply, some cable connections can be removed. Compared to semi-modular and fully-modular PSUs, the non-modular power supply is less expensive. Gamers with transparent glass cabinets use a modular power supply so they may cut out extra cords and organize their cables more effectively.


For gaming PCs, the power supply’s effectiveness is crucial. You don’t want to invest in a power source that wastes energy and produces excessive heat. Power supply units have efficiency ratings to help with understanding. A power supply unit (PSU) with an efficiency of 80% wastes 20% of its output as heat. You should, of course, select a power supply with higher efficiency.

You should be aware that power supplies are given metallic codes to help customers distinguish amongst power supplies with different levels of efficiency. The gold power supplies are more efficient even though they have the same efficiency percentage as the bronze power supplies. Choose a PSU with 80+ certifications in these areas.


To keep your system cool and the temperature under control, you need a fan. The minimum and maximum fan sizes are 90mm and 140mm, respectively. Depending on their size, there may be more than one fan. While other companies need you to purchase the fan separately, certain brands include it with the power supply unit.


Because a power supply unit ensures proper power transmission in the gaming PC’s components, you should search for connections that are practical. The 24 PIN cable, which powers the entire motherboard, is the most crucial connector. There are also cable connectors for the 8 PIN CPU and 6 PIN GPU.

The 24 PIN connector should be plenty in most cases, although some motherboards call for CPU and GPU connectors. Additionally, it is advantageous to have extra connectors on your power supply that you may utilize when you install various expansion cards to your motherboard in the future. This is another reason to use a completely modular power supply, which will allow you to add and remove cables as needed.


When it comes to power supply units, warranty is crucial. A PSU shouldn’t be bought without a warranty. A power supply can be harmed by short circuits, overvoltages, and overpowers. A corporation will offer a sizable warranty if it is confident in its goods. You should look for power supply warranties that are at least three to five years old. Nevertheless, only a few businesses offer a 10-year warranty. The corporation is more confident in its products and the product is probably better when the guarantee duration is longer.


Does gaming power supply matter?

Yes, a power supply is a crucial part of a gaming computer. A power supply must effectively control power distribution while simultaneously meeting the demand of the system’s components. The motherboard and other PC components have a longer lifespan when the power supply is of good quality. Additionally, it provides extra area for overclocking your CPU and GPU for improved and quicker performance.

A 750W PSU is Suitable for Gaming?

For a typical gaming PC, a 550W power supply should be adequate. However, a 750W power supply is required if your computer has two graphics cards installed. Therefore, 750W is sufficient for a smooth gaming experience provided you have a strong gaming PC. Otherwise, a 550W PSU will do.

Which Power Supply is Necessary for a Gaming Computer?

Because it relies on the power rating of the components in your PC, it is challenging to forecast the power supply that your gaming PC will require. The requirement for a power supply will increase as your gaming PC becomes more powerful and high-end. A gaming PC should ideally have a power supply that is between 550W and 750W.

Which PSU is Necessary for My GPU?

Since the GeForce RTX 3090 only uses about 350 watts when your PC is running alone, Nvidia presently advises a 750W power supply for their top-tier graphics cards.

Is a Power Supply of 1000W Suitable for Gaming?

Even a power supply in the 800W–1000W range will be too powerful for 90% of gamers. Again, unless you plan to run a variety of video card configurations now or in the future and engage in excessive system tuning, there really isn’t a need for this much power.
