Power Supply Bronze Vs Gold

Power Supply Bronze Vs Gold: What You Need to Know

When it comes to building a PC, choosing the right power supply is just as important as the other components. And when it comes to power supplies, the efficiency rating can be a deciding factor. The two most commonly compared efficiency ratings are Bronze and Gold. In this article, we’ll take a look at what Bronze and Gold efficiency ratings mean and how they compare.

What is Power Supply Efficiency?

Power supply efficiency is the ratio of DC output power to AC input power. In simpler terms, it’s how much of the power your PSU is drawing from your wall outlet actually makes it to your computer. This is measured in a percentage, with the rest of the power being converted into heat.

For example, if you have a 500-watt power supply and it’s rated at 80% efficiency, it will consume 625 watts from the wall outlet (500 / .8). In this case, the rest of the power (125 watts) is lost as heat.

When it comes to efficiency ratings, there are several levels. These levels are defined by the 80 Plus program, which is a certification program designed to promote efficient power supply units. The levels are as follows:

– 80 Plus: 80% efficiency at 20%, 50%, and 100% load.
– 80 Plus Bronze: 82% efficiency at 20%, 85% efficiency at 50%, and 82% efficiency at 100% load.
– 80 Plus Silver: 85% efficiency at 20%, 88% efficiency at 50%, and 85% efficiency at 100% load.
– 80 Plus Gold: 87% efficiency at 20%, 90% efficiency at 50%, and 87% efficiency at 100% load.
– 80 Plus Platinum: 90% efficiency at 20%, 92% efficiency at 50%, and 89% efficiency at 100% load.
– 80 Plus Titanium: 90% efficiency at 10%, 92% efficiency at 20%, 94% efficiency at 50%, and 90% efficiency at 100% load.

So, as you can see, Gold efficiency is a step up from Bronze, but how much of a difference does this make in the real world?

Bronze Vs Gold Efficiency: What’s the Difference?

The difference in efficiency between Bronze and Gold power supplies may not seem significant, but it can add up over time. A Gold PSU will be more efficient than a Bronze PSU, which means it draws less power from the wall outlet, and as a result, will produce less heat.

Lower heat production means a longer lifespan for your power supply, as heat is one of the largest contributors to component failure. Additionally, less heat generation also means less noise, as your fans won’t have to work as hard to keep your PC cool.

Another significant difference between Bronze and Gold power supplies is the cost. Gold units are typically more expensive than Bronze units, which can be a deal-breaker for some users.


Q: Is it worth it to get a Gold PSU over a Bronze one?

A: If you have the budget for it, a Gold PSU is worth the investment. The increased efficiency will save you money in the long run, and the reduced heat and noise are also a plus.

Q: How much can I save with a Gold PSU compared to a Bronze one?

A: On average, a Gold PSU will save you around 5-10% on your electricity bill compared to a Bronze PSU.

Q: Will a Gold PSU work with my PC?

A: Yes, Gold PSUs are compatible with all modern PCs, and they are available in a wide range of wattages to suit your needs.

Q: Do I need a Gold PSU for gaming?

A: While a Gold PSU isn’t necessary for gaming, it’s a good investment if you want your PC to be as efficient as possible. Additionally, if you’re running a high-end gaming PC, a Gold PSU will be able to handle the power demands more efficiently.

Q: Can a Gold PSU be overclocked?

A: Yes, a Gold PSU can be overclocked. However, it’s important to make sure that you don’t exceed the maximum wattage output of your PSU, as this can cause damage to your components.

In conclusion, while the difference between Bronze and Gold power supplies may seem small, it can make a big difference in the long run. If you have the budget for it, a Gold PSU is a wise investment that will save you money on your electricity bill and extend the lifespan of your power supply.
