750W PSUs

Ideal for running at maximum capacity, 750W PSUs are a great choice for a power supply which operates at a higher capacity than your PCs requirements. They're also ideal for providing extra space for when you want to upgrade your system.

Vital PSUs

Firstly, your computer will not word without a power supply distributing electric to all of the components in your PC. Yes surprisingly, they are often overlooked. The Power Supply Unit (PSU) gives power to your complete system, and if you do not use the correct one, it could prove costly. And, as usual, the cheapest option is rarely the best solution. Remember that Ebuyer has a specialist team of advisors who can help you select the correct PSU for your computer, and there is live chat on our website.

Connectivity

Not only do you need the right PSU, you also need the right cable to link everything up. When you buy a PSU it should really come with the appropriate cables, but it is always useful to know what the connections look like. The type of cable will vary, depending on your build, but the following are the most popular types.

24-pin Motherboard

Power in your computer is not always distributed in the same way. It varies depending on what type of motherboard you have. However, the 24-pin connector/cable is regularly used to power important features such as the chipset and PCIe.

4/8-pin CPU

This connector provides power to your CPU: Modern CPUs draw more power than the 24-pin motherboard configuration can provide, which is why the additional 4/8 pin cable came into use. Depending on the manufacturer, the CPU cable generally plugs in to the motherboard at the top left side, near the I/O on a standard layout. Lots of PSUs have multiple SATA connections on one cable, which has been designed to reduce the number of cables required.

How Many Watts is enough?

This is usually one of the first questions that people ask when they are looking to buy a new PSU. So, exactly how many watts do you need? As you would expect, this really depends on the unique needs of your computer. As a general rule, you need more power if your system is more complex. For example, if you want to run a desktop with high-end motherboard and dual GPUs, then you will need more power supply than if you had a simpler system.

Higher wattage

Generally, it is better to go for a higher wattage than you need, as more power is always better than not enough. If you have estimated that your system needs 500 watts, which is a standard wattage for a straightforward build, then choosing a PSU with 600 or 650 watt output is preferable as it give you more power to work with.

If there is a sudden demand for more power, your PSU should be able to tackle the higher output for a short while, but should not be expected to run at those higher wattages for a sustained period of time. Always make sure the PSU you purchase has sufficiently high continuous power output, and do not choose solely by peak power capabilities or you could run into trouble.
