No device or equipment can function without the proper power supply, making this one of the most important investments in your project, product development, or operation.
It’s easy to get caught off guard by the power supply price, though. We get asked all the time - why are power supplies so expensive? Simply put, you get what you pay for. Although a low-cost power supply is appealing, it may come with reliability or efficiency problems.
So, how much does a power supply cost? It depends! You’ll find power supplies ranging in price from under $10 to thousands of dollars, which only adds to the confusion and uncertainty.
We’ve put together this pricing guide to help you set your expectations. Just know that the best deals are here at Bravo Electro thanks to our long-standing, close-working relationships with leading power supply manufacturers.

When you need to connect multiple power supplies together to reach your desired power output, you'll have two approaches you can take: connecting power supplies in parallel or connecting power supplies in series.
Each method has its pros and cons, which is why we’re going to break down the nuances between connecting power supply in series vs parallel to leave you feeling confident in your next steps.
Connecting power supplies in series will increase the output voltage, whereas connecting those same power supplies in parallel would raise the output current. So which approach makes the most sense for your application?
Power Supply in Series Power Supply in Parallel Voltage increases – The total output voltage is the sum of all power supplies in series, but the current remains the same as the lowest-rated unit. Current increases – The total current output is the sum of all power supplies in parallel, while voltage remains the same as the lowest-rated unit.

Your power supply unit (PSU) keeps your operation running, whether it’s powering life-critical medical devices or supporting manufacturing robot operations. Downtime can be costly, so how long do power supplies last?
Power supply lifespan is impacted by quality of the unit, usage, environment, and more. Some of the high-quality AC-DC power supply and DC converter units we sell at Bravo Electro can last 5 years or more.
We'll take a closer look at the PSU lifespan and what affects it along with what to do if you notice the bad power supply symptoms and need to get a replacement fast - for that, look no further than Bravo Electro.

Choosing the right power supply types is not something that can be taken lightly no matter the application. We see our customers struggle with picking between an isolated vs non-isolated power supply time and time again. So, we’ll break down the differences below to leave you with complete clarity.
Isolated power supplies are safer, quieter, and capable of providing multiple output voltages since they provide electrical separation between input and output. On the other hand, non-isolated power supplies are smaller, more affordable, and great when electrical isolation isn’t essential.
Here’s a chart showing which makes sense for you between an isolated and non-isolated PSU:
Factor Isolated Power Supply Non-Isolated Power Supply Applications Medical devices, industrial automation, avionics, high-voltage power conversion, sensitive measurement equipment. Consumer electronics, automotive applications, battery-powered devices, embedded systems. Safety & Compliance Required for high-risk - March 05, 2025 36
Starting March 4, 2025, new U.S. tariffs are raising costs for power supplies, especially those from China, where rates now combine a 10% base tariff with existing 35% Section 301 tariffs—potentially totaling up to 45% for electronics like AC/DC power supplies. For businesses and consumers relying on Bravo Electro's power supplies, these changes mean higher prices and supply chain challenges. But there are legal ways to minimize tariff impacts. This 2025 guide explores solutions using Taiwan, Philippines, and U.S. manufacturers, plus a free resource coming soon. Let's save on tariffs with Bravo Electro now!
1. Understanding U.S. Tariffs on Power Supplies in 2025
The U.S. has escalated tariffs on imports to bolster domestic manufacturing, impacting power supplies classified under Harmonized Tariff Schedule (HTS) codes like 8504.40 (electrical transformers, static converters). As of March 4, 2025:
- China: A new 10% tariff on all Chinese goods (per President Trump's announcement) stacks with

The battery you use for your system influences everything from performance and efficiency to long-term reliability and operational costs. It’s not a decision you can take lightly.
But with so many options on the market it’s easy to find yourself stuck in analysis paralysis. We’ll help you narrow it down to one of two options: a LiFePO4 vs lead acid battery. These are among the most common styles you’ll have at your disposal today.
Each has its place, with LiFePO4 batteries providing high-efficiency, lightweight performance that lasts. They’re the gold standard in modern power storage solutions.
On the other hand, lead acid batteries have been the trusted, cost-effective choice for industrial and commercial settings for decades - but their performance, reliability, and efficiency all fall short of the LiFePO4 design. So is it worth paying a premium for this battery?
Let’s find out. We’ll compare and contrast the LiFePO4 battery vs lead acid battery below to leave you with a crystal clear

When searching for the ideal energy source for any system you need to power, you have two main options: linear vs switching power supply.
So what’s the difference between a linear and switching power supply, and which is right for your unique needs? Each has its own unique advantages and disadvantages that are important to consider when choosing the best power supply.
But, this decision can get overwhelming - particularly for those who aren’t power supply savvy. Fortunately, we are - and we’re here to unpack everything you need to know. Here are the key takeaways on this switching power supply vs linear power supply comparison:
- Switching power supplies are more efficient and compact. This comes at the cost of more noise. You’ll find these in manufacturing, aviation, and other industries.
- Linear power supplies have a quicker response to fluctuations in load. They’re quieter, but less efficient and a bit larger. Common in communications, medical equipment, and laboratory devices.
