The PSUs (power supply units) are often overlooked, but they are one of the vital components of a desktop PC. Many mid-range PC builds work great with a 750W power supply unit (PSU) since they do not draw more than 650W. The PSUs are commonly used in various electronic systems, such as servers, gaming consoles, desktop computers, etc.
In this article, we will reveal what a 750W power supply unit is, what it can charge, and the best Jackery Explorer Portable Power Stations that can power a wide range of appliances. For example, the Jackery Explorer 600 Plus Portable Power Station and Jackery Explorer 1000 Plus Portable Power Station are two popular charging solutions with 632Wh and 1264Wh, respectively.
What Is 750W Power Supply?
A 750W power supply unit (PSU) is one of the critical PC components and can supply up to 750W of power. In other words, the term "750" signifies the maximum amount of power that the power supply unit can deliver to all the components. However, a 750W PSU does not always consume 750W. One important thing to note is that the system draws 400W, and the PSU will deliver 400W — regardless of the maximum capable output.
If an electronic device is marked as 750W/240V, it means the device draws 750 watts and operates at a voltage of 240V. Having this information handy ensures the device is used with the correct power supply to prevent malfunction or damage. Jackery Explorer Portable Power Stations are well-designed to supply continuous electricity to essential appliances like PCs, laptops, WiFi, etc.
What Can A 750W Power Supply Power?
A 750W power supply is generally enough for most single GPU configurations with a decent CPU and multiple hard drives. If you have two high-end graphic cards, you need a power supply of at least 750W. On the other hand, for multi-GPU systems, you'll need at least 1000W or more. Here's a table revealing different computer graphic cards that a 750W power supply can charge:

Jackery Explorer Portable Power Stations are compact, robust, and sturdy charging solutions that can charge most computers and PCs. For example, the Jackery Explorer 1000 Plus Portable Power Station with a battery capacity of 1264Wh can charge a gaming computer (300W) for 3.3 hours.
How Does A 750W Power Supply Work?
A 750W power supply works by taking the AC electricity from the wall outlet and converting it into unregulated DC electricity. The input power transformer reduces the voltage, typically stepping it down to the voltage that's required by the load. The filtering part in the power supply reduces the distinct waves that remain after the AC power converts to DC. The regulator then smooths out the waves by voltage regulation.


How Many Watts Does A Computer Use?
On average, a computer or a laptop draws nearly 30-70W of electricity. Some large desktops and gaming computers require more energy between 200-500W. Here's how many watts a computer uses:

How to Choose The 750W Power Supply?
A power supply is one of the crucial components in the desktop PC and plays a vital role in supplying power to the system. The proper PSU will help you keep the system protected and efficient. Here are a few things to remember when choosing a 750W power supply unit:
Connector
The PSU you purchase comes with all the necessary cables. The 24-pin motherboard powers the chipset and PCIe, whereas the 4/8-pin CPU provides stable power to the CPU. Cables can be used in various combinations, such as 6, 8, 6+6, 8+6, and 8+8 pin connectors. As the name suggests, the SATA power connector is designed to power SATA storage devices.
Wattage
When choosing a power supply, the first question is: How much wattage is enough? The correct answer depends on how much power your system draws. For example, if you've calculated that your system uses 600W, choosing a PSU with 750W output could be a good option. You'll also need to consider the continuous power and peak power capabilities of a new PSU.
Protection
Many advanced power supplies come with a built-in failsafe. These safety mechanisms can protect the PSU and keep the system safe from unexpected power surges. Always look for built-in protection like OVP (over-voltage protection), which can shut down the PSU if the system detects excessive voltage.
Efficiency
Wattage and protection are important considerations when choosing a desktop power supply, but so is efficiency. As a general rule of thumb, the 750W power supply should be at least 80% efficient, meaning only 20% of power should be lost as heat. The efficiency of the PSU is determined by its performance in a 115V system. The more efficient the PSU, the less power it will use and the less heat it will generate.
750W Power Supply FAQs
What size of power station do I need for a PC?
The size of the power station required to charge a PC will depend on the appliance's wattage consumption. As a general rule of thumb, it is essential to choose a power station that can supply more electricity than is required for the appliance being charged.
Calculating the runtime of your Jackery Solar Generator when it powers any household or outdoor appliance is straightforward. Go to the product page for the Jackery Solar Generator you are interested in, find the Running Time Simulator/Calculator, and input your appliance’s wattage. In a second, you’ll receive an estimated duration. For example, the Jackery Solar Generator 600 Plus can run a 500W coffee maker for approximately 1.0 hours. Kindly note that the actual results may vary slightly.
Is 750 watts good for a power supply?
Yes, a 750W power supply is good for most people, depending on the CPU and other components of the system you're running.
How much electricity does 750 watts use?
A 750W appliance used for one hour will consume around 0.75kWh of electricity per hour.
If you want to calculate the amount of electricity, here's the formula:
Electricity = 750Wh ÷ 1000 = 0.75kWh.
Does a gaming PC use a lot of electricity?
The average mid-range gaming PC consumes 300-500W of electricity, which is equivalent to 1400kWh used annually. Many high-end gaming consoles use up to 1000W per hour under full load.
Final Thoughts
A 750W power supply unit is a good choice for building a custom workstation or gaming PC. With this PSU, you can efficiently run two graphics cards. But before you choose the best PSU wattage and brand, it is essential to check the motherboard manual to ensure you get a power supply that includes all the necessary cables.
If you're looking for a reliable and portable power station that can charge most computers and PCs, the Jackery Explorer Portable Power Stations act like a great choice. They are available in different sizes, so you can choose the power station that's ideal for many appliances. These power stations are compatible with solar panels to charge devices off-grid.
