750w power supply

Choosing the right power supply is very important when building a gaming PC. It is one of the most important components of your PC, and people usually don’t pay enough attention to it.

You should first find out how much power you actually need for the components inside your PC. After calculating it, get the power supply which supplies more power than your components need.

Because getting an equal or underpowered PSU can result in unexpected shutdowns, and your PC might not perform at its maximum capability.

There are some other factors as well to check before choosing a PSU for your PC. We will discuss all of them one by one later in this article.

Today we will focus on choosing the best 750W power supply for your PC.

What To Look In A Best 750W Power Supply


Before purchasing a power supply, there are multiple factors you should check for. For example, the capacity of the unit, if it was modular or not, and fan noise, etc.

Getting the right power supply is necessary as it is one of the most important parts of your PC and other components of your PC depend on it. If it is of not a good quality, it may cause immediate failure of other components on your PC and may cause unexpected shutdowns.

We will discuss all the factors before getting a power supply in detail one by one.


Fully Modular, Semi-Modular, And Non-Modular


Non-modular PSUs are those in which all the wires are permanently attached to the unit. You cannot add or remove extra wires even if you need to. This leads to clutter in your PC as even those wires stay in your PC, which you don’t need. Those cables also hinder the airflow of your PC, which results in higher temperatures in many cases.

Semi-modular power supplies have the 24 pin motherboard cable, one PCIe cable with 2-3 connectors, and 1 cable with 2-3 SATA connectors attached. These are the necessary cables to boot up the basic components of the system.

Types of Modularities In PSUs

You can always connect more cables if you plan to add more components. Semi-modular power supplies are better than non-modular ones because they relatively cause a lesser mess. But they are still not as good as fully modular ones.

Then come the fully modular power supplies. Such PSUs do not come with even a single cable attached to them. You will only attach the cables you need, and you can remove them when you don’t need them.

Plus, you can upgrade your PSU anytime without removing all the cables from your system. You’ll only need have to remove the cables from the power supply and remove it.

Modular power supply result in the cleanest setup builds as only those cables will be attached to it, which you truly need. This will also improve the airflow, which will result in lower temperatures and better overall performance.

Fully modular power supplies are obviously the best option to consider among these 3. But you have to keep in mind that they are the most expensive ones and the non-modular ones are the cheapest.


How Much Do You Need?


This factor is obviously very important. You must calculate how much power does your PC need then select a power supply according to your requirements.

Image of Highs Tier ASUS PSUs

If you are using up to 3080 GPU, then the 750 watts power supply should be enough for you. But if you are getting an RTX 3090, then you might need to get an 850 watts or more unit.

And not just the GPU; you should also check the power requirements of other components in your PC. If you are using a normal CPU, then you may get up to a 750 W power supply. But if you are planning to upgrade to AMD Ryzen Threadripper in the near future, you should get more than 850 watts PSU.


Continuous Wattage And Peak Wattage


There are 2 ways the capability of PSU can be expressed. One is peak wattage, and the other one is continuous wattage. You should always focus on the continuous wattage rating before getting a power supply.

If the product is not rated in continuous power rating and only rated in peak power rating, you should avoid that product because there is no real standard of what peak means as it might provide peak wattage for a few seconds or minutes only.


Rails (Optional) & Voltage Stability


A multi-rail power supply is one that has 2 different 12-volt rails for 2 different power supplies. There are some other rails as well, which are called minor rails, but they perform little to no role these days.

Image of Asus ROG Thor showing 519 watts

The 5 volt rails os one of the most important ones as they provide power to the USB ports on your device. There are some other rails as well, including a 3-volt rail.

Then there is a standby rail that receives the signal to turn on the PC from stand-by mode. Without this rail, the PC won’t even boot.

The voltage stability is also very important. Whatever voltage your PSU is providing to your components, it should be normal and should not fluctuate as it might harm your PC.


Form Factors


The form factor is also an important thing to consider. You should first select your case then choose the components, including your PSU around it. If your casing is of compact size, you should get a compact power supply.

Image of Form Factors of PSU's

But if your casing is big enough and it can fit a bigger power supply, go for such a power supply by spending some extra money.


Fan Noise & Cable Management


There are some power supplies available in the market which automatically shut down the fan when it is not using enough power. This will ultimately result in silent operation, and you will not be disturbed by noise during light work.

Image of Corsair Power Supply

Cable management is also very important as bad cable management hinders the airflow in the case, which will cause increased temperature and it will cause performance issues.

Modular power supplies play a very important role in this area. In modular power supplies, you’ll only need to connect the cables you really need, and you can detach them at any time. Fewer cables will cause less clutter which will improve airflow and less temperature overall.


Understand The Certifications


Certifications are given to power supplies to have an idea of how efficient the product is. There are 3 scenarios of load on which the product is rating. Those scenarios are 20% of maximum load, 50% of maximum load, and 100% of maximum load.

Power Supply Certification Explained

The original 80 Plus certification was simple. It simply meant that the power supply should be at least 80% efficient at 20, 50, and 100% of the maximum load.

Later on, in around 2008 and 2009, 4 more certifications were introduced, and they were called 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, and 80 Plus Platinum.

The 80 Plus Platinum has a power efficiency of more than 90%, which is amazingly good. The 80 Plus Platinum power supplies are always around 90% power efficient under all load scenarios.


Final Verdict:

All of the power supplies we have recommended above are of very good quality. They all have excellent certifications, and they can handle most of the gaming systems on the market.

Most of them are modular, and we always recommend to must go for a modular one as it reduces the clutter by a lot and causes better airflow overall.
