What is the best efficiency rating for a PSU?

Although most manufacturers of power supplies tend to have the same PSU efficiency rating system of 80 plus, there are ratings you should look out for. They include Bronze, Silver, Gold, Titanium, and Platinum.

An 80 Plus Titanium efficiency rating tends to be a bit more efficient than Bronze which means the parts will waste less power or heat during the AC to DC conversion. This efficiency is mostly measured using three load levels, including 20%, 50%, and 100%.

While most PSUs tend to have an efficiency rating of 50%, Titanium PSUs tend to perform better even under heavy load and a high-performance computer. Higher efficiency will also mean that the internal components are subjected to less heat and, in turn, have a longer lifespan.

Although such PSUs may cost a bit higher than others, they tend to be more reliable and come with great warranties.

What Do You Consider Before Buying the Best Power Supply for Gaming?

1. Wattage

When choosing a power supply, the first thing you need is to determine the total wattage required for the build. You can use an online wattage calculator, for example, the Extreme Power supply calculator by Outer Vision to determine the total wattage you require for the build.

Once you determine the wattage required, we recommend account for a 20% buffer for safety and future-proofing. This helps you dodge the cost of getting a new PSU if you chose to install Crossfire or SLI GPUs later on.

2. Ratings

It would be better if you always strived to have a good efficiency rating on a PSU. An 80 Plus certification standard guarantees efficiency, accurate wattage, and active PFC. The main purpose of APFC is to make the apparent power equal to true power. Your PSU will have better voltage regulation with all these benefits, allowing your PC to perform as stable as possible.

3. Modularity

When it comes to modularity, there are three main options;

  • Direct Cable- This is a cheap power supply option, but it is not the best for an enthusiast gamer who may need to swap the build from time to time. It is also much harder to deal with since all the PSU cables come directly from the PSU housing.
  • Semi-Modular- With this one, all required cables come from the PSU case, such as the CPU (4+4) connector, PCI-e (6+2) connector, and ATX Power (20+4) connector. Other cables like SATA (15-pin) connectors and Molex (4-pin) will allow you to remove them at will. The semi-modular PSUs have decent cable management and average pricing.
  • Full Modular- These PSUs have removable cables making the installation easy and the cable management extremely easy. Although they are reliable and allows one to change builds frequently, they can be a bit expensive.

4. Design

When it comes to the design, it is important to determine the durability of the PSU. The best power supplies will have a great build quality and an impressive warranty to build the trust of the product. You can check the reviews to determine how durable the power supply will be.

For enthusiasts, the best power supply for gaming should have an impressive design, and the color should match the theme of your room or PC. Although this is not a very important thing to consider, it is important to have it in mind so that you can pick one within your style.

5. Price

Most of the above features will highly depend on your budget. For this reason, you should determine your budget and find a good option within your budget. The prices may fluctuate depending on the brand, modularity, efficiency, as well as other features. Luckily, there is an option for every reasonable budget you have.

Frequently Asked Questions (FAQs) on Power Supplies for Gaming

1. What is a good power supply wattage for gaming?

You don't need to do a lot of mathetics or have a degree in rocket science to know the wattage requirements. This is because you can easily check the recommended system power requirement on the specs list of your current and future graphics cards. You can also use an online power or wattage calculator to get a more accurate figure.

2. Is 750W good for gaming?

Generally, a 750w PSU is good enough for a high-end gaming PC. However, if you're curious about how much wattage the PC will need, then it is better to use a PSU online calculate to give a rough estimate of the wattage you need.

3. Is a higher watt power supply better?

Since the main function of a power supply is to provide power to the device. This means that the more robust the device or application is, the more power it requires, and in turn, the higher the wattage you will need from the power supply. Therefore, depending on your device, it is better to have a higher wattage unit than a lower wattage unit.

4. Can a power supply short circuit?

If the gaming computer is not correctly connected to the power supply, a short circuit may occur. A defective power supply can also cause a power problem or short circuit with your gaming computer.
