A PSU is a critical component of your computer system. The electricity from your home or office outlet typically uses an alternating current (AC) and comes in at a high voltage. Your PSU converts this to the lower-voltage direct current (DC) that your computer's components require. A PSU distributes the converted power to various parts of your ...
Jun 9, 2012 · Power supply vendors all spec their PSUs differently, but we have two thumbs, and so I offer a second rule of thumb: Power supplies are generally the most efficient when at 60-80% load (at the low ...
Jun 9, 2023 · While a higher wattage PSU does not directly improve gaming performance, the wattage of your PSU is going to determine what your gaming PC can do in terms of maximum performance. The wattage of a ...

A computer's power supply is essentially the heart of the system. It pumps electricity to all the components, enabling them to function properly. If the heart is weak (in this case, has too-low wattage), it might fail to provide sufficient power, leading to performance issues or stability problems. Conversely, a PSU with excess wattage wastes (a ti...
To figure out how much wattage you need, start by listing all the components of your system. This includes everything from your CPU and GPU to your storage drives, RAM, fans, and even the number of USB devices you plan on using. Anything that needs power to operate should be on the list. If you leave out a bunch of small components, they can add up...
Different components have different power requirements. High-end GPUs, such as the latest Nvidia and AMD models, can demand 300 watts or more, while high-performance CPUs can use over 100 watts. In contrast, components like SSDs, HDDs, and RAM modules typically require less than 10 watts each. Therefore, a system with multiple GPUs or an overclocke...
The efficiency rating of a PSU is the difference between the power it draws from the wall and the power it provides to your system. For instance, a PSU with an 80 PlusGold rating is at least 87% efficient at 20-100% load, meaning that 13% of power is wasted as heat. Higher efficiency ratings, like 80 Plus Platinum or Titanium, have less waste and a...
When choosing a PSU, it's wise to account for future upgrades. If you plan on adding another hard drive, upgrading your GPU, or expanding your RAM in the future, consider a PSU that exceeds your current wattage needs by (for example) 20-30%.
