Buying Guide for Best PC Power Supplies


Choosing between two power supplies can be mind hectic for some. Several factors should be considered before opting for one option. We shall analyze some of these factors and how they impact our purchasing sense when buying the best power supply for our PC. The first thing that can’t ever be neglected while purchasing is wattage. Your PC always has some wattage requirements which have to be addressed by your power supply. If your power supply cannot support the wattage requirements of your system, then it’s obviously of no use for your PC, your PC will heat up, and you’ll be going back and forth to your local computer repair shop. The (CPU) and (GPU) are two of the primary sources of power consumption in your system. Your PSU should be able to support these two components in your PC, along with other more minor details that help make up your entire PC. To know how much power your PC consumes, you could either ask your manufacturer or search about it on the internet. You will find various PSU calculators to help you understand how much power supply you will require to run your system.


The other factor that has to be considered is the rating system. We all buy things online, and the first thing we look at is the rating and reviews of the component we are buying. However, the rating system is entirely different when it comes to PSUs. It generally means how efficiently a PSU can convert power from the socket of your wall to the lower voltage, which is required by your PC’s components. The name 80 plus rating system indicates that those power supplies are assured not to waste more than 20% of the total consumption. This should be an essential buying factor if we want to go green and save electricity as much as possible. There even are five further sub-categories to help you choose from, i.e., titanium, platinum, white, gold, and bronze. White is the lowest-end in the five, while titanium is the most premium. It is still better to buy the white-rated PSU than buy an un-rated one as it will still be more electricity efficient than the latter.


The next thing to be considered is rails, and no, I am not talking about your actual metro rails. Rails are a little more intricate subject to talk about as there’s always this certain ambiguity about them. Rails mean the number of paths through which power can be supplied to multiple PC components. Rail is an engraved circuit tract via which a unit extracts energy. A single PSU of rail only contains a single route. A single rail power lures the unit’s power and supplies it to all the parts connected to its ends. This helps ensure that all the PC components have adequate ability to operate. However, this elephant in the room comes with single-unit rails free of cost. A power surge would put your hard drive at glaring peril. This problem could be counter-feted by using multi-rail PSU’s, which will help ensure data safety on your hard drive during a power surge. They do so with every rail’s innate over current and short current impediment system. One should always consider multi-rail PSUs over single ones as they would be helpful in power surges.


The next thing that should always be considered is pin connectors. While choosing the PSU, you must contemplate that it contains all the necessary connectors. There are three available connectors out of which each power supply comes with one, i.e., 6-pin cable, 8-pin cable, and a 6+2 cable. For instance, GPU usually requires a 6-pin or an 8-pin connector. It should also consider how efficient your PC’s cooling systems are and what type of connectors your motherboard uses. 


Last but not least, modularity is also often taken into account while choosing a suitable PSU to buy. It merely means the power connector cables can be affixed or detached from the PSU. It reduces entanglement and complexity in wires by efficiently removing useless wires from the cable clutter. This not only makes your system looks neater and more relaxed, but it also provides it with more space for airflow. Although modularity is an essential factor that should always be considered while choosing a PSU, it shouldn’t be considered without running a cost-benefit analysis on your own, as even with a non-modular power connector, the performance of your system would not be much affected. In summary, you have to consider all of the above factors to make an efficient buy. If you don’t want to go into so many details and only want to feel a thing or two, you just have to check out the wattage requirements of your system with the PSU and ensure that your PSU contains all the necessary connectors as per your PC’s requirements.
