Power Supply Units [PSUs] are often overlooked during a PC build despite its crucial part in determining the reliability of the entire system. All your PC components depend on PSU for power. Even if you’re on a tight budget, you don’t want to make any compromises when it comes to the power supply. We’re here to discuss factors you need to consider before purchasing the PSU for your rig.
Factors need to be considered before purchasing a PSU -
There is no point in buying a PSU with way more potential power than you’ll ever use. A PSU calculator web page or software can be handy in finding a rough estimation about the wattage requirement of your build. However, it is not recommended purchasing a PSU just above your system's power needs. A PSU delivers maximum efficiency with 40 to 60 percent load. Besides, the performance of a PSU declines with time. So, you better opt for a PSU capable of taking you through your next few upgrades for multiple years.
You must buy a PSU that fits inside your PC case. Higher-wattage PSUs tend to be a bit longer [compared to typical 5.5 inch PSUs] to house the additional power components they need. This may create issues with cable routing or even with placing other internal components inside the case. So, it is a must to go for a PSU compatible with your PC case.
Different PSUs come with different types of power connectors, including 20/24-pin power, 4-pin ATX12V, 4-pin Molex, floppy, SATA, 6-pin PCI-Express graphics and 8-pin PCI-Express graphics. You must get a power supply with connectors your PC components required. If you don’t find required connectors in a PSU within your budget, check what cable adaptors the PSU includes to extenuate the problem.
If you have limited space in your case, it’s worth paying extra for a modular power supply. A modular PSU let you plug in the power cables you need and leave the extra ones. This facility will help reducing cable clutter that can hinder airflow and heat up the atmosphere inside the case.
